Raw Normal View History

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 v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v102r22 release. byuu says: Changelog: - higan: Emulator::Interface::videoSize() renamed to videoResolution() - higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize() - higan: added video display rotation support to Video - GBA: substantially improved audio mixing - fixed bug with FIFO 50%/100% volume setting - now properly using SOUNDBIAS amplitude to control output frequencies - reduced quantization noise - corrected relative volumes between PSG and FIFO channels - both PSG and FIFO values cached based on amplitude; resulting in cleaner PCM samples - treating PSG volume=3 as 200% volume instead of 0% volume now (unverified: to match mGBA) - GBA: properly initialize ALL CPU state; including the vital prefetch.wait=1 (fixes Classic NES series games) - GBA: added video rotation with automatic key translation support - PCE: reduced output resolution scalar from 285x242 to 285x240 - the extra two scanlines won't be visible on most TVs; and they make all other cores look worse - this is because all other cores output at 240p or less; so they were all receiving black bars in windowed mode - tomoko: added "Rotate Display" hotkey setting - tomoko: changed hotkey multi-key logic to OR instead of AND - left support for flipping it back inside the core; for those so inclined; by uncommenting one line in input.hpp - tomoko: when choosing Settings→Configuration, it will automatically select the currently loaded system - for instance, if you're playing a Game Gear game, it'll take you to the Game Gear input settings - if no games are loaded, it will take you to the hotkeys panel instead - WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls into combined "Hardware" - WS(C): converted rotation support from being inside the core to using Emulator::Video - this lets WS(C) video content scale larger now that it's not bounded by a 224x224 square box - WS(C): added automatic key rotation support - WS(C): removed emulator "Rotate" key (use the general hotkey instead; I recommend F8 for this) - nall: added serializer support for nall::Boolean (boolean) types - although I will probably prefer the usage of uint1 in most cases

If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot.

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 v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.
