goyuken ed2b690f75 add memory domains to gambatte
appears to work, but i don't really have much of anything to test on it
ramwatch is horribly slow

beirich bf504d1220 gen: work on sprite masking/overflow code. substantially improved. Fixes Sonic 1 title screen, Galaxy Force 2 level select, Landstalker sprite masking, and improved nemesis' test rom. Still something amiss in Sonic 2 title screen. 2012-09-11 05:00:45 +00:00
goyuken d84f13275e add IsLagFrame, LagCount, Frame to Snes savestates 2012-09-11 01:50:55 +00:00

goyuken 578e247524 add lag counter to LibsnesCore
per ilari, this should work correctly on certain games that poll the input in a particular way.  however, it is completely non-functional on many other games.  core digging is required for anything better.

zeromus ad6910fd74 snes-some beginning steps on graphics debugging tools. nothing to see yet, move along 2012-09-06 08:32:25 +00:00
brandman211 fd1560177e -Implemented Colored Squares mode. It looks sensible in one of the improperly loaded ROMs that triggers it.
-Masked the Color Stack registers. This prevents the previously mentioned ROM from throwing an ArgumentException in ColorToRGBA.
2012-09-06 08:02:49 +00:00
brandman211 a6f11a7ade -The STIC now displays the encoded background color when one is provided.
--The only time I've seen this was in a game that used FGBG mode, and it looked messed up.
-Implemented the parsing of the background for Color Stack mode.
--Because the STIC Registers aren't populated, this doesn't do anything. I'm not sure when this is supposed to occur.
-Determined when Colored Squares mode is active. I'll try to implement this mode shortly.

-Corrected the maskings. The top tiles look perfect now, but the text isn't showing up yet.
2012-09-06 06:20:50 +00:00
brandman211 06022c9076 -Added Read/WriteMemory to the STIC so that it can access the RAM it needs to draw the screen.
--Did the same for the PSG because why not.
-Discovered that the Commando HLT happens after the CPU goes idle, so there's no point in further investigating the issue until I emulate that.
-Parsed the BACKTAB cards for the STIC's Draw().
-Attempted to draw the screen using the aforementioned cards.
--I'm only trying to apply color to the foreground.
---Instead of converting the FG color to RGBA, I'm making it all white for now.
--There's clearly some sanity to what's being drawn, so I think each 8x8 card is being drawn in the right place.
--I think the next step is trying to make each individual card draw properly.
--I believe the algorithm for populating the FrameBuffer is VERY inefficient in the way it accesses memory. Will need some suggestions as to how I can rewrite this.

goyuken a85dadcf7d did a bunch of listening tests with libsnes and metaspu. switched to vecna metaspu
it seems to be the most stable when the system is fast enough to maintain approximately 100% speed.

also fixed up metaspu in dumping and switched it to vecna.  i can now have clean audio while running libsnes with lua script and ffmpeg dumping.

goyuken b0e3a332d8 abstract resampling functionality into IStereoResampler for testing purposes
add two example resamplers that implement this: LinearResampler and CubicResampler.  both are very basic and sound like shit compared to libresample4j
ultimately, a single good resampler with a better license than libresample4j should be selected and used
2012-09-05 21:21:35 +00:00
goyuken 0430ec91c8 add resampler based on libresample4j (LGPL)
hook that up to libsnes, so libsnes audio now goes through libresample4j and then metaspu
it sounds ok

brandman211 1a760096bc -Laid out the groundwork for the video provider.
--VirtualHeight / Width will be useful due to how the scanlines are doubled on TVs, but for now, I will just be drawing to scale.
-Enabled XOR@, SAR, and COMR. Advanced Dungeons & Dragons provided more test cases.
-Noticed that Commando, as well as some other games, triggers a HLT. This should be looked into later.

brandman211 44e03b1923 -Changed the amount of pending cycles to add when the STIC sets SR1.
--This number is fairly arbitrary, and I don't know why it works, but for now, it does.
--The values of INTRM don't match up exactly, but I think this is mostly a logging issue, though I still need to look into this.
-Fixed the Overflow Flag calculation.
--My original formula didn't compare the signs of the operands.
--It always needs to use the original operands, not the 2s complement one.
--As such, a result parameter has been added.
-Fixed the detection of a double swap, shift, and rotate in the related instructions. Ironically, I shifted one too many bits in my detection.
-Masked the result of left shifts and rotates to 0xFFFF so that the flags are calculated properly.
-Made RSWD (un)set the right flags.
-Enabled GSWD, MVI, SARC, CMP@, ADD, SUB@, INCR, RRC, SLR, SLL, RLC, ADDR, SUBR, SLLC, CMPR, and RSWD.
-COMR, NEGR, ADCR, SAR, ANDR, SUB, AND, XOR, and XOR@ remain disabled as I have yet to hit any test cases for them.

At this point, IntelliHawk is executing instructions indefinitely with what seems to be perfect results! I think I'm ready to hook up the screen.

brandman211 ca8b778a52 -Noted interrupts in the log.
-Added and Interrupted flag to make it so that interrupts only trigger once per falling edge.
-For now, interrupts take 28 cycles.
-Made it so that the STIC tracks Pending / Total Executed Cycles just like the CPU.
-Forwarded the cycles executed in the CPU to the STIC's Execute.
-SR1 is now inverted when there are no pending cycles.
--If SR1 is high, 14394 cycles are added to the pending cycles.
--If SR1 is low, 3791 cycles are added to the pending cycles.

brandman211 26b1d06b7a -Simplified the CPU / STIC connection.
-Made FrameAdvance handle the pending cycle loop. During each iteration, it runs one instruction and ticks the STIC accordingly.
2012-08-14 03:58:11 +00:00
brandman211 9100232547 -Made connections between the signal pins on the CP1610 and the STIC.
--Not sure why the STIC has any connection to the SST, but the docs on the SST are virtually non-existent from what I could find.
--I took advantage of Func and Action instead of passing bool references to both devices. I think this makes sense.
-Added reset functions for both devices.

My comparison log for INTRM is still weird because it says it is true initially (Expected) and remains as such after the first instruction (A bit odd). I think this happens because the STIC is supposed to "tick" and shift SR1 to false immediately, but the STIC tick happens after the CPU tick, and the CPU tick is where the logging happens. I need to find a better place to put this logging, and I need to implement the STIC ticking for IntelliHawk. I'm not positive how to approach the latter issue as I assume a tick means one instruction execution, and my executions happen in a loop on the CPU, which has no reference to the STIC, so I'm not sure where this fits into the equation.

brandman211 5239b4f55b -Separated the STIC and PSG memory map logic into new objects.
-Foreground / Background | Color Stack Mode
--Actually made a boolean for it (FGBG).
--Reading from a write-only STIC alias of $21 does change the STIC into Color Stack mode, but it doesn't actually read.
--Color stack mode is enabled when $21 or its alias is read and it is disabled (FGBG) when written its written, both having to occur during VBlank Period 1.
---This is what I gathered from the wiki, but I'm confused as to why it says that "The STIC stays in this mode until the program accesses location $21 again." I'm assuming this doesn't mean the mode changes on every access because then I don't understand why a read would change to a different mode than a write.
--FGBG is disabled by default. I don't think it matters.

-Made the logging separator generate before an instruction instead of after the register states. This is quite petty, but I don't like the separator at the end of the file.

I hit an infinite loop, and I'm very very certain it's happening because I don't have an interrupt system yet. Time to stop avoiding that!

-Several instructions are now executed in succession until it hits the unimplemented "XORR R5, R5".

I should probably refactor Disassemble and Execute to label registers as source / destination to avoid further confusion at some point. My disassembly might have the source / destination registers flipped as well.

I didn't get around to implementing bank-switched ranges, but I don't think it's worth worrying about that right now considering that the Intellicart is not marked as readable at the initial PC, so something is either wrong or I need to implement more things before this will work. I think I'll put Intellicarts on hold and try to get a .int / .bin to run in the meantime.

brandman211 2553ac50bb -As I'm not going to know what I'm doing if I keep hacking away at zeromus' old core blindly, I'm writing a new one.
--It's going to be based heavily based on Imran Nazar's "GameBoy Emulation in Javascript" series. I figure it's better that I learn by emulation (Har har) instead of spending more time reading references than programming.
--Finished the memory management (Part 2).
--adelikat:
---Do I implement the required functions for IEmulator and IVideoProvider now, do it later, or is this something you or zeromus would do (Like for the API)?
---At what point should we have the emulator actually use this core instead of zeromus'? As terrible as he says his is, this one doesn't do anything yet. Still, I need some mechanism of testing it.

beirich df59686cbb Fix crash in PCE Coryoon when attempting to access disabled TurboCD ports 2012-05-26 20:21:00 +00:00
brandman211 b29c9835ff -Separated the logging from the save state function.
-Made it so that the log only opens when logging is true and that the file closes upon destruction.
--Still, BizHawk says that it can't open the file again when I load a game again. This is because the emulator class gets recreated without deleting the original one every time you load a game.
---adelikat convinced me not to care about this.
-Fixed the initial state of the GB CPU:
--It was setting AF to 0x01, not A. This is effectively setting F to 0x01, which gets overwritten later anyway.
--Two BIOS flags were used in different places; merging them gets the PC to start in the right place.
-By fixing the initial state, most of the log now matches up.
--The only differences are the VBA has some repeated records (Where all of the registers, including PC, are the same as the previous record) whereas BizHawk doesn't.
--This very well might be an issue with how I'm logging it
--Alternatively, it could be some kind of lagging mechanism.
--I'm not sure which version is even correct...VBA is far from accruate.
--All in all, considering that the vast majority of the diff comes out as the same, I think I fixed the biggest CPU related bug. Will investigate more later.

brandman211 9f8144ec58 -Set the number of cycles per frame to 70224.
-Inverted the colors; according to http://imrannazar.com/GameBoy-Emulation-in-JavaScript:-Graphics, 0 is white, 1 is light gray, 2 is dark gray, and 3 is black, which is the opposite of the norm.

brandman211 cd0016343f Done trying to optimize the PPU's FrameAdvance. We may have saved some processing time, but it's not very consistent. 2012-05-06 06:04:00 +00:00
brandman211 05157997f1 -Added a very basic fix to the graphics scaling issue per adelikat's advice.
--Gets worse as the scale increases.
--For x3, the box doesn't increase size, but the box still changes position. I think there might be a difference between the TargetZoomFactor and the actual screen size, so perhaps we should tie this to something else.
-Working on very small optimizations to the NES PPU with CorruptedSyntax...this is more fun, so we'll do this first.
--Eliminated an entire loop.
--Branched to two loops instead of branching for every iteration in one loop.
--Got rid of some redundant instructions using temporary variables.
--This may be completely premature, but I seem to have gained a few FPS from doing this. For me, I get 38-39 FPS where I'd previously get 33-34.
