Raw Normal View History

Update to v098r04 release. byuu says: Changelog: - SFC: fixed behavior of 21fx $21fe register when no device is connected (must return zero) - SFC: reduced 21fx buffer size to 1024 bytes in both directions to mirror the FT232H we are using - SFC: eliminated dsp/modulo-array.hpp [1] - higan: implemented higan/video interface and migrated all cores to it [2] [1] the echo history buffer was 8-bytes, so there was no need for it at all here. Not sure what I was thinking. The BRR buffer was 12-bytes, and has very weird behavior ... but there's only a single location in the code where it actually writes to this buffer. It's much easier to just write to the buffer three times there instead of implementing an entire class just to abstract away two lines of code. This change actually boosted the speed from ~124.5fps to around ~127.5fps, but that's within the margin of error for GCC. I doubt it's actually faster this way. The DSP core could really use a ton of work. It comes from a port of blargg's spc_dsp to my coding style, but he was extremely fond of using 32-bit signed integers everywhere. There's a lot of opportunity to remove red tape masking by resizing the variables to their actual state sizes. I really need to find where I put spc_dsp6.sfc from blargg. It's a great test to verify if I've made any mistakes in my implementation that would cause regressions. Don't suppose anyone has it? [2] so again, the idea is that higan/audio and higan/video are going to sit between the emulation cores and the user interfaces. The hope is to output raw encoding data from the emulation cores without having to worry about the video display format (generally 24-bit RGB) of the host display. And also to avoid having to repeat myself with eg three separate implementations of interframe blending, and so on. Furthermore, the idea is that the user interface can configure its side of the settings, and the emulation cores can configure their sides. Thus, neither has to worry about the other end. And now we can spin off new user interfaces much easier without having to mess with all of these things. Right now, I've implemented color emulation, interframe blending and SNES horizontal color bleed. I did not implement scanlines (and interlace effects for them) yet, but I probably will at some point. Further, for right now, the WonderSwan/Color screen rotation is busted and will only show games in the horizontal orientation. Obviously this must be fixed before the next official release, but I'll want to think about how to implement it. Also, the SNES light gun pointers are missing for now. Things are a bit messy right now as I've gone through several revisions of how to handle these things, so a good house cleaning is in order once everything is feature-complete again. I need to sit down and think through how and where I want to handle things like light gun cursors, LCD icons, and maybe even rasterized text messages. And obviously ... higan/audio is still just nall::DSP's headers. I need to revamp that whole interface. I want to make it quite powerful with a true audio mixer so I can handle things like SNES+SGB+MSU1+Voicer-Kun+SNES-CD (five separate audio streams at once.) The video system has the concept of "effects" for things like color bleed and interframe blending. I want to extend on this with useful other effects, such as NTSC simulation, maybe bringing back my mini-HQ2x filter, etc. I'd also like to restore the saturation/gamma/luma adjustment sliders ... I always liked allowing people to compensate for their displays without having to change settings system-wide. Lastly, I've always wanted to see some audio effects. Although I doubt we'll ever get my dream of CoreAudio-style profiles, I'd like to get some basic equalizer settings and echo/reverb effects in there.

Update to v098r06 release. byuu says: Changelog: - emulation cores now refresh video from host thread instead of cothreads (fix AMD crash) - SFC: fixed another bug with leap year months in SharpRTC emulation - SFC: cleaned up camelCase on function names for armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes - GB: added MBC1M emulation (requires manually setting mapper=MBC1M in manifest.bml for now, sorry) - audio: implemented Emulator::Audio mixer and effects processor - audio: implemented Emulator::Stream interface - it is now possible to have more than two audio streams: eg SNES + SGB + MSU1 + Voicer-Kun (eventually) - audio: added reverb delay + reverb level settings; exposed balance configuration in UI - video: reworked palette generation to re-enable saturation, gamma, luminance adjustments - higan/emulator.cpp is gone since there was nothing left in it I know you guys are going to say the color adjust/balance/reverb stuff is pointless. And indeed it mostly is. But I like the idea of allowing some fun special effects and configurability that isn't system-wide. Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad.
