Update to v095r08 release. byuu says: Changelog: - added preliminary WASAPI driver (it's really terrible, though. Patches most welcome.) - all of processor/ updated to auto fn() -> ret syntax - all of gb/ updated to auto fn() -> ret syntax If you want to test the WASAPI driver, then edit ui-tomoko/GNUmakefile, and replace audio.xaudio2 with audio.wasapi Note that the two drivers are incompatible and cannot co-exist (yet. We can probably make it work in the future.) All that's left for the auto fn() -> ret syntax is the NES core and the balanced/performance SNES components. This is kind of a big deal because this syntax change causes diffs between WIPs to go crazy. So the sooner we get this done and out of the way, the better. It's also nice from a consistency standpoint, of course.

Update to v087r09 release. byuu says: Split apart necdsp: core is now in processor/upd96050 (wish I had a better name for it, but there's no family name that is maskable.) I would like to support the uPD7720 in the core as well, just for completeness' sake, but I'll have to modify the decoder to drop one bit from each mode. So ... I'll do that later. Worst part is even if I do, I won't be able to test it :( Added all of Cydrak's changes. I also simplified LDMIA/STMIA and PUSH/POP by merging the outer loops. Probably infinitesimally slower, but less code is nicer. Maybe GCC optimization will expand it, who knows.

Update to v104r10 release. byuu says: Changelog: - processor/upd96050: per manual errata note, SGN always uses SA1; never SB1 [fixes v104r09 regression] - processor/upd96050: new OV1/S1 calculation that doesn't require OV0 history buffer [AWJ] - processor/upd96050: do not update DP in OP if DST=4 [Jonas Quinn] - processor/upd96050: do not update RP in OP if DST=5 [Jonas Quinn] - resource: recreated higan+icarus icons, higan logo as 32-bit PNGs So higan v104r08 and earlier were 930KiB for the source tarball. After creating new higan and icarus icons, the size jumped to 1090KiB, which was insane for only adding one additional icon. After digging into why, I discovered that ImageMagick defaults to 64-bit!! (16-bits per channel) PNG images when converting from SVG. You know, for all those 16-bit per channel monitors that don't exist. Sigh. Amazingly, nobody ever noticed this. The logo went from 78.8KiB to 24.5KiB, which in turn also means the generated resource.cpp shrank dramatically. The old higan icon was 32-bit PNG, because it was created before I installed FreeBSD and switched to ImageMagick. But the new higan icon, plus the new icarus icon, were both 64-bit as well. And they're now 32-bit. So the new tarball size, thanks to the logo optimization, dropped to 830KiB. Cydrak had some really interesting results in converting higan's resources to 8-bit palletized PNGs with the tRNS extension for alpha transparency. It reduces the file sizes even more without much visual fidelity loss. Eg the higan logo uses 778 colors currently, and 256 represents nearly all of it very well to the human eye. It's based off of only two colors, the rest are all anti-aliasing. Unfortunately, nall/image doesn't support this yet, and I didn't want to flatten the higan logo to not have transparency, in case I ever want to change the about screen background color.

Update to v104r08 release. byuu says: Changelog: - processor/upd96050: code cleanups - processor/upd96050: improved emulation of S1/OV1 flags [thanks to Cydrak, Lord Nightmare] - tomoko/settings/audio: reduced the size of the frequency/latency combo boxes to show longer device driver names Errata: I need to clear regs.sr in uPD96050::power() Note: the S1/OV1 emulation is likely not 100% correct yet, but it's a step in the right direction. No SNES games actually use S1/OV1, so this shouldn't result in any issues, I'd just like to have this part of the chip emulated correctly.

Update to v087r09 release. byuu says: Split apart necdsp: core is now in processor/upd96050 (wish I had a better name for it, but there's no family name that is maskable.) I would like to support the uPD7720 in the core as well, just for completeness' sake, but I'll have to modify the decoder to drop one bit from each mode. So ... I'll do that later. Worst part is even if I do, I won't be able to test it :( Added all of Cydrak's changes. I also simplified LDMIA/STMIA and PUSH/POP by merging the outer loops. Probably infinitesimally slower, but less code is nicer. Maybe GCC optimization will expand it, who knows.

After creating new higan and icarus icons, the size jumped to 1090KiB, which was insane for only adding one additional icon. After digging into why, I discovered that ImageMagick defaults to 64-bit!! (16-bits per channel) PNG images when converting from SVG. You know, for all those 16-bit per channel monitors that don't exist. Sigh. Amazingly, nobody ever noticed this. The logo went from 78.8KiB to 24.5KiB, which in turn also means the generated resource.cpp shrank dramatically. The old higan icon was 32-bit PNG, because it was created before I installed FreeBSD and switched to ImageMagick. But the new higan icon, plus the new icarus icon, were both 64-bit as well. And they're now 32-bit. So the new tarball size, thanks to the logo optimization, dropped to 830KiB. Cydrak had some really interesting results in converting higan's resources to 8-bit palletized PNGs with the tRNS extension for alpha transparency. It reduces the file sizes even more without much visual fidelity loss. Eg the higan logo uses 778 colors currently, and 256 represents nearly all of it very well to the human eye. It's based off of only two colors, the rest are all anti-aliasing. Unfortunately, nall/image doesn't support this yet, and I didn't want to flatten the higan logo to not have transparency, in case I ever want to change the about screen background color.

And they're now 32-bit. So the new tarball size, thanks to the logo optimization, dropped to 830KiB. Cydrak had some really interesting results in converting higan's resources to 8-bit palletized PNGs with the tRNS extension for alpha transparency. It reduces the file sizes even more without much visual fidelity loss. Eg the higan logo uses 778 colors currently, and 256 represents nearly all of it very well to the human eye. It's based off of only two colors, the rest are all anti-aliasing. Unfortunately, nall/image doesn't support this yet, and I didn't want to flatten the higan logo to not have transparency, in case I ever want to change the about screen background color.

Update to v087r09 release. byuu says: Split apart necdsp: core is now in processor/upd96050 (wish I had a better name for it, but there's no family name that is maskable.) I would like to support the uPD7720 in the core as well, just for completeness' sake, but I'll have to modify the decoder to drop one bit from each mode. So ... I'll do that later. Worst part is even if I do, I won't be able to test it :( Added all of Cydrak's changes. I also simplified LDMIA/STMIA and PUSH/POP by merging the outer loops. Probably infinitesimally slower, but less code is nicer. Maybe GCC optimization will expand it, who knows.

Update to v095r08 release. byuu says: Changelog: - added preliminary WASAPI driver (it's really terrible, though. Patches most welcome.) - all of processor/ updated to auto fn() -> ret syntax - all of gb/ updated to auto fn() -> ret syntax If you want to test the WASAPI driver, then edit ui-tomoko/GNUmakefile, and replace audio.xaudio2 with audio.wasapi Note that the two drivers are incompatible and cannot co-exist (yet. We can probably make it work in the future.) All that's left for the auto fn() -> ret syntax is the NES core and the balanced/performance SNES components. This is kind of a big deal because this syntax change causes diffs between WIPs to go crazy. So the sooner we get this done and out of the way, the better. It's also nice from a consistency standpoint, of course.

Update to v087r09 release. byuu says: Split apart necdsp: core is now in processor/upd96050 (wish I had a better name for it, but there's no family name that is maskable.) I would like to support the uPD7720 in the core as well, just for completeness' sake, but I'll have to modify the decoder to drop one bit from each mode. So ... I'll do that later. Worst part is even if I do, I won't be able to test it :( Added all of Cydrak's changes. I also simplified LDMIA/STMIA and PUSH/POP by merging the outer loops. Probably infinitesimally slower, but less code is nicer. Maybe GCC optimization will expand it, who knows.
