Update to v087r04 release. byuu says: GBA stuff re-added. Only thing missing that was there before is the ARM branch opcode. Since we're going to be staring at it for a very long time, I added a more interesting test video pattern. Went from 6fps to 912fps. Amazing what being able to divide can do for a frame rate.

Update to v088r01 release. byuu says: - GB::CPU::Core -> Processor::LR35902 - Processor::LR35902 -> jump table to switch table - GB::LCD -> GB::PPU - static frequency for DMG (no multiplication on clock ticks) - GB::PPU::interface->videoRefresh() moved outside scheduler (use host thread) - namespace NES -> Famicom - namespace SNES -> SuperFamicom - namespace GB -> GameBoy - namespace GBA -> GameBoyAdvance - removed boot.rom writeout in GB::System

Update to v094r32 release. byuu says: Lots more timing improvements to GBA emulation. We're now ahead of everything but mGBA. Mario & Luigi is still hanging in battles, so I guess my prefetch simulation isn't as good as Cydrak's previous attempt, no surprise.

#include "prefetch.cpp"
Update to v094r35 release. byuu says: GBA timings are *almost* perfect now. Off by 1-3 cycles on each test, sans a few DMA ones that seem to not run at all according to the numbers (crazy.)

#include "bus.cpp"
Update to v099r13 release. byuu says: Changelog: - GB core code cleanup completed - GBA core code cleanup completed - some more cleanup on missed processor/arm functions/variables - fixed FC loading icarus bug - "Load ROM File" icarus functionality restored - minor code unification efforts all around (not perfect yet) - MMIO->IO - mmio.cpp->io.cpp - read,write->readIO,writeIO It's been a very long work in progress ... starting all the way back with v094r09, but the major part of the higan code cleanup is now completed! Of course, it's very important to note that this is only for the basic style: - under_score functions and variables are now camelCase - return-type function-name() are now auto function-name() -> return-type - Natural<T>/Integer<T> replace (u)intT_n types where possible - signed/unsigned are now int/uint - most of the x==true,x==false tests changed to x,!x A lot of spot improvements to consistency, simplicity and quality have gone in along the way, of course. But we'll probably never fully finishing beautifying every last line of code in the entire codebase. Still, this is a really great start. Going forward, WIP diffs should start being smaller and of higher quality once again. I know the joke is, "until my coding style changes again", but ... this was way too stressful, way too time consuming, and way too risky. I'm too old and tired now for extreme upheavel like this again. The only major change I'm slowly mulling over would be renaming the using Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as easily confused with the (u)int_t types ... but we'll see. I'll definitely continue to change small things all the time, but for the larger picture, I need to just accept the style I have and live with it.

#include "io.cpp"
Update to v087r26 release. byuu says: Changelog: - fixed FIFO[1] reset behavior (fixes audio in Sword of Mana) - added FlashROM emulation (both sizes) - GBA parses RAM settings from manifest.xml now - save RAM is written to disk now - added save state support (it's currently broken, though) - fixed ROM/RAM access timings - open bus should mostly work (we don't do the PC+12 stuff yet) - emulated the undocumented memory control register (mirror IWRAM, disable I+EWRAM, EWRAM wait state count) - emulated keypad interrupts - emulated STOP (freezes video, audio, DMA and timers; only breaks on keypad IRQs) - probably a lot more, it was a long night ... Show stoppers, missing things, broken things, etc: - ST018 is still completely broken - GBC audio sequencer apparently needs work - GBA audio FIFO buffer seems too quiet - PHI / ROM prefetch needs to be emulated (no idea on how to do this, especially PHI) - SOUNDBIAS 64/128/256khz modes should output at that resolution (really, we need to simulate PWM properly, no idea on how to do this) - object mosaic top-left coordinates are wrong (minor, fixing will actually make the effect look worse) - need to emulate PPU greenswap and color palette distortion (no idea on how do this) - need GBA save type database (I would also LIKE to blacklist / patch-out trainers, but that's a discussion for another day.) - some ARM ops advance the prefetch buffer, so you can read PC+12 in some cases

#include "memory.cpp"
Update to v087r16 release. byuu says: Fixed the r15 mask per Cydrak. Added DMA support (immediate + Vblank + Hblank + HDMA) with IRQ support. Basically only missing FIFO reload mode for the APU on channel 2. Added background linear renderer (tilemap mode.) Added really inefficient pixel priority selector, so that all BGs+OBJ could be visible onscreen at the same time. As a result of the above: * Mr. Driller is our first fully playable game * Bakunetsu Dodge Ball Fighters is also fully playable * Pinobee no Daibouken is also fully playable Most games (15 of 16 tested) are now showing *something*, many things look really really good in fact. Absolutely essential missing components: - APU - CPU timers and their interrupts - DMA FIFO mode - OBJ affine mode - BG affine mode - BG bitmap mode - PPU windows (BG and OBJ) - PPU mosaic - PPU blending modes - SRAM / EEPROM (going to rely on a database, not heuristics. Homebrew will require a manifest file.)

#include "dma.cpp"
Update to v087r18 release. byuu says: Merged Cydrak's r17c changes: - BG affine mode added - BG bitmap mode added - OBJ affine mode added - fixed IRQ bug in THUMB mode (fixed almost every game) - timers added (broke almost every game, whee.) Cydrak is absolutely amazingly awesome and patient. This really wouldn't be happening without him. Also fixed some things from my end, including greatly improved sprite priorities, and a much better priority sorter. Mr. Driller looks a lot better now.

Update to v095r07 release. byuu says: Changelog: - entire GBA core ported to auto function() -> return; syntax - fixed GBA BLDY bug that was causing flickering in a few games - replaced nall/config usage with nall/string/markup/node - this merges all configuration files to a unified settings.bml file - added "Ignore Manifests" option to the advanced setting tab - this lets you keep a manifest.bml for an older version of higan; if you want to do regression testing Be sure to remap your controller/hotkey inputs, and for SNES, choose "Gamepad" from "Controller Port 1" in the system menu. Otherwise you won't get any input. No need to blow away your old config files, unless you want to.

Update to v094r31 release. byuu says: This WIP scores 448/920 tests passed. Gave a shot at ROM prefetch that failed miserably (ranged from 409 to 494 tests passed. Nowhere near where it would be if it were implemented correctly.) Three remaining issues: - ROM prefetch - DMA timing - timers (I suspect it's a 3-clock delay in starting, not a 3-clock into the future affair) Probably only going to be able to get the timers working without heroic amounts of effort. MUL timing is fixed to use idle cycles. STMIA is fixed to set sequential at the right moments. DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer. In other news ... I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those Window_configure issues go away. I realize I was leaking Display* handles in the X-video driver while I was looking at it, so I fixed those. I added DT_NOPREFIX so the Windows ListView will show & characters correctly now.

auto CPU::Enter() -> void {
Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

This is about five hours worth of extremely delicate work. Any slight errors could break emulation in extremely bad ways. Let's hold off on extensive testing until the next WIP, after I do the same to the PPU. So far ... endrift's SOUNDCNT_X I/O test is failing, although that code didn't change, so clearly I messed up SOUNDCNT_H somehow ... To compile on Windows: 1. change nall/string/platform.hpp line 47 to return slice(result, 0, 3); 2. change ruby/video.wgl.cpp line 72 to auto lock(uint32_t*& data, uint& pitch, uint width, uint height) -> bool { 3. add this line to the very top of hiro/windows/header.cpp: #define boolean FuckYouMicrosoft

Update to v087r07 release. There was a "v087r07pre" release that I unfortunately missed. byuu says (about v087r07pre): Creates the bsnes/processor folder. This has a shared ARM core there which both the GBA and ST018 inherit. There are going to be separate decoders, and revision-specific checks, to support the differences between v3+. In the future, I also want to move the other processor cores here: - GBZ80 (GB, GBC) - 65816 (SNES CPU, SA-1) - NEC uPD (7725, 96050, maybe 7720 just for fun) - Hitachi HG51B169 - SuperFX - SPC700 - 65(C?)02 Basically, the GBA/ST018 forces my hand to start coding a bit more like a multi-system emulator. Right now, the ST018 is broken. Hence the pre. Apparently the GBA core being used now has some bugs. So this'll be a nice way to stress-test the GBA core a bit before we make it to ARMwrestler. byuu says (about v087r07): Both snes/chip/armdsp and gba/cpu use processor/arm now. Fixed THUMB to execute the BL prefix and suffix separately. I can now get the GBA BIOS stuck in some kind of infinite loop. Hooray ... I guess?

Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Update to v094r31 release. byuu says: This WIP scores 448/920 tests passed. Gave a shot at ROM prefetch that failed miserably (ranged from 409 to 494 tests passed. Nowhere near where it would be if it were implemented correctly.) Three remaining issues: - ROM prefetch - DMA timing - timers (I suspect it's a 3-clock delay in starting, not a 3-clock into the future affair) Probably only going to be able to get the timers working without heroic amounts of effort. MUL timing is fixed to use idle cycles. STMIA is fixed to set sequential at the right moments. DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer. In other news ... I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those Window_configure issues go away. I realize I was leaking Display* handles in the X-video driver while I was looking at it, so I fixed those. I added DT_NOPREFIX so the Windows ListView will show & characters correctly now.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Show stoppers, missing things, broken things, etc: - ST018 is still completely broken - GBC audio sequencer apparently needs work - GBA audio FIFO buffer seems too quiet - PHI / ROM prefetch needs to be emulated (no idea on how to do this, especially PHI) - SOUNDBIAS 64/128/256khz modes should output at that resolution (really, we need to simulate PWM properly, no idea on how to do this) - object mosaic top-left coordinates are wrong (minor, fixing will actually make the effect look worse) - need to emulate PPU greenswap and color palette distortion (no idea on how do this) - need GBA save type database (I would also LIKE to blacklist / patch-out trainers, but that's a discussion for another day.) - some ARM ops advance the prefetch buffer, so you can read PC+12 in some cases

Update to v094r31 release. byuu says: This WIP scores 448/920 tests passed. Gave a shot at ROM prefetch that failed miserably (ranged from 409 to 494 tests passed. Nowhere near where it would be if it were implemented correctly.) Three remaining issues: - ROM prefetch - DMA timing - timers (I suspect it's a 3-clock delay in starting, not a 3-clock into the future affair) Probably only going to be able to get the timers working without heroic amounts of effort. MUL timing is fixed to use idle cycles. STMIA is fixed to set sequential at the right moments. DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer. In other news ... I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those Window_configure issues go away. I realize I was leaking Display* handles in the X-video driver while I was looking at it, so I fixed those. I added DT_NOPREFIX so the Windows ListView will show & characters correctly now.

Update to v087r04 release. byuu says: GBA stuff re-added. Only thing missing that was there before is the ARM branch opcode. Since we're going to be staring at it for a very long time, I added a more interesting test video pattern. Went from 6fps to 912fps. Amazing what being able to divide can do for a frame rate.

Update to v087r08 release. byuu says: Added some more ARM opcodes, hooked up MMIO. Bind it with mmio[(addr 000-3ff)] = this; inside CPU/PPU/APU, goes to read(), write(). Also moved the Hitachi HG51B core to processor/, and split it apart from the snes/chip/hitachidsp implementation. This one actually worked really well. Very clean split between MMIO/DMA and the processor core. I may move a more generic DMA function inside the core, not sure yet. I still believe the HG51B169 to be a variant of the HG51BS family, but given they're meant to be incredibly flexible microcontrollers, it's possible that each variant gets its own instruction set. So, who knows. We'll worry about it if we ever find another HG51B DSP, I guess. GBA BIOS is constantly reading from 04000300, but it never writes. If I return prng()&1, I can get it to proceed until it hits a bad opcode (stc opcode, which the GBA lacks a coprocessor so ... bad codepath.) Without it, it just reads that register forever and keeps resetting the system, or something ... I guess we're going to have to try and get ARMwrestler working, because the BIOS seems to need too much emulation code to do anything at all.

Update to v092r09 release. byuu says: This will be another massive diff from the previous version. All of higan was updated to use the new foo& bar syntax, and I also updated switch statements to be consistent as well (but not in the disassemblers, was starting to get an RSI just from what I already did.) phoenix/{windows, cocoa, qt} need to be updated to use "string foo" instead of "const string& foo", and after that, the major diffs should be finished. This archive is the first time I'm posting my copy-on-write, size+capacity nall::string class, so any feedback on that is welcome as well.

Update to v095r03 release and icarus 20151107. byuu says: Note: you will need the new icarus (and please use the "no manifest" system) to run GBA games with this WIP. Changelog: - fixed caching of r(d) to pass armwrestler tests [Jonas Quinn] - DMA to/from GBA BIOS should fail [Cydrak] - fixed sign-extend and rotate on ldrs instructions [Cydrak] - fixed 8-bit SRAM reading/writing [byuu] - refactored GBA/cartridge - cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash - things won't crash horribly if you specify a RAM size larger than the largest legal size in the manifest - specialized MROM / SRAM classes replace all the shared read/write functions that didn't work right anyway - there's a new ruby/video.glx2 driver, which is not enabled by default - use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet - I'm not going to support OpenGL2 on Windows/OS X, because these OSes don't ship ancient video card drivers - probably more. What am I, clairvoyant? :P For endrift's tests, this gets us to 1348/1552 memory and 1016/1260 timing. Overall, this puts us back in second place. Only no$ is ahead on memory, but bgba is even more ahead on timing.

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)

Mosaic is what concerns me the most, I've no idea if I'm doing it correctly. But anything is probably better than nothing, so there's that. I don't really notice the effect in Metroid Fusion.

[A lot of individual fixes for the ARM core from Cydrak - Ed.] Also new is pipeline_decode() to fetch data, and IME/IE/IF support, and an ARM::processor.irqline flag that triggers IRQs at 0x18. Only Vblank is hooked up, which is what SWI 4 was waiting on previously. I'm sure my interrupt support is horribly broken and wrong. I was never able to really figure out IE/IF on the Game Boy, so there's no question this is even worse. It's now going crazy and writing 0 to IE forever now after the Vblank IRQ triggers.

SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P I recall from the GB APU that you can't just assign values for the APU MMIO regs. They do odd reload things as well. Also, was using MMIO read code like this: return ( (flaga << 0) || (flagb << 1) || (flagc << 2) ); Logical or doesn't work so well with building flags :P Bad habit from how I split multiple conditionals across several lines. So ... r14 is basically what r13 should have been yesterday, delaying my schedule by yet another day :(

Update to v097r17 release. byuu says: Changelog: - ruby: if DirectSoundCreate fails (no sound device present), return false from init instead of crashing - nall: improved edge case return values for (basename,pathname,dirname,...) - nall: renamed file_system_object class to inode - nall: varuint_t replaced with VariadicNatural; which contains .bit,.bits,.byte ala Natural/Integer - nall: fixed boolean compilation error on Windows - WS: popa should not restore SP - GBA: rewrote the CPU/APU cores to use the .bit,.bits functions; removed registers.cpp from each Note that the GBA changes are extremely major. This is about five hours worth of extremely delicate work. Any slight errors could break emulation in extremely bad ways. Let's hold off on extensive testing until the next WIP, after I do the same to the PPU. So far ... endrift's SOUNDCNT_X I/O test is failing, although that code didn't change, so clearly I messed up SOUNDCNT_H somehow ... To compile on Windows: 1. change nall/string/platform.hpp line 47 to return slice(result, 0, 3); 2. change ruby/video.wgl.cpp line 72 to auto lock(uint32_t*& data, uint& pitch, uint width, uint height) -> bool { 3. add this line to the very top of hiro/windows/header.cpp: #define boolean FuckYouMicrosoft

Update to v087r14 release. byuu says: Fixed aforementioned issues. [From a previous post: - mul was using r(d) instead of r(n) for accumulate. - mull didn't remove c/v clear. - APU register mask was broken, so SOUNDBIAS was reading out wrong. - APU was only mapping 0x088 and not 0x089 as well. - Halfword reads in CPU+PPU+APU were all reading from the low address each time.] All CPU+PPU registers are now hooked up (not that they do anything.) SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P I recall from the GB APU that you can't just assign values for the APU MMIO regs. They do odd reload things as well. Also, was using MMIO read code like this: return ( (flaga << 0) || (flagb << 1) || (flagc << 2) ); Logical or doesn't work so well with building flags :P Bad habit from how I split multiple conditionals across several lines. So ... r14 is basically what r13 should have been yesterday, delaying my schedule by yet another day :(

Update to v087r16 release. byuu says: Fixed the r15 mask per Cydrak. Added DMA support (immediate + Vblank + Hblank + HDMA) with IRQ support. Basically only missing FIFO reload mode for the APU on channel 2. Added background linear renderer (tilemap mode.) Added really inefficient pixel priority selector, so that all BGs+OBJ could be visible onscreen at the same time. As a result of the above: * Mr. Driller is our first fully playable game * Bakunetsu Dodge Ball Fighters is also fully playable * Pinobee no Daibouken is also fully playable Most games (15 of 16 tested) are now showing *something*, many things look really really good in fact. Absolutely essential missing components: - APU - CPU timers and their interrupts - DMA FIFO mode - OBJ affine mode - BG affine mode - BG bitmap mode - PPU windows (BG and OBJ) - PPU mosaic - PPU blending modes - SRAM / EEPROM (going to rely on a database, not heuristics. Homebrew will require a manifest file.)

Update to v094r35 release. byuu says: GBA timings are *almost* perfect now. Off by 1-3 cycles on each test, sans a few DMA ones that seem to not run at all according to the numbers (crazy.)

Update to v099r13 release. byuu says: Changelog: - GB core code cleanup completed - GBA core code cleanup completed - some more cleanup on missed processor/arm functions/variables - fixed FC loading icarus bug - "Load ROM File" icarus functionality restored - minor code unification efforts all around (not perfect yet) - MMIO->IO - mmio.cpp->io.cpp - read,write->readIO,writeIO It's been a very long work in progress ... starting all the way back with v094r09, but the major part of the higan code cleanup is now completed! Of course, it's very important to note that this is only for the basic style: - under_score functions and variables are now camelCase - return-type function-name() are now auto function-name() -> return-type - Natural<T>/Integer<T> replace (u)intT_n types where possible - signed/unsigned are now int/uint - most of the x==true,x==false tests changed to x,!x A lot of spot improvements to consistency, simplicity and quality have gone in along the way, of course. But we'll probably never fully finishing beautifying every last line of code in the entire codebase. Still, this is a really great start. Going forward, WIP diffs should start being smaller and of higher quality once again. I know the joke is, "until my coding style changes again", but ... this was way too stressful, way too time consuming, and way too risky. I'm too old and tired now for extreme upheavel like this again. The only major change I'm slowly mulling over would be renaming the using Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as easily confused with the (u)int_t types ... but we'll see. I'll definitely continue to change small things all the time, but for the larger picture, I need to just accept the style I have and live with it.

Update to v095r07 release. byuu says: Changelog: - entire GBA core ported to auto function() -> return; syntax - fixed GBA BLDY bug that was causing flickering in a few games - replaced nall/config usage with nall/string/markup/node - this merges all configuration files to a unified settings.bml file - added "Ignore Manifests" option to the advanced setting tab - this lets you keep a manifest.bml for an older version of higan; if you want to do regression testing Be sure to remap your controller/hotkey inputs, and for SNES, choose "Gamepad" from "Controller Port 1" in the system menu. Otherwise you won't get any input. No need to blow away your old config files, unless you want to.

Update to v087r04 release. byuu says: GBA stuff re-added. Only thing missing that was there before is the ARM branch opcode. Since we're going to be staring at it for a very long time, I added a more interesting test video pattern. Went from 6fps to 912fps. Amazing what being able to divide can do for a frame rate.
