License-compatible code we might want to import #838

This is not a comprehensive list or a specific to-do, more like a brainstorm. Add more if you know of them.

@DopefishJustin That core uses a bunch of weird time-skip bullshit to kludge the timings into working right, according to byuu.

My suggestion is importing the PCI code from PCem!

wilbertpol commented 8 years ago

FWIW, I started working on the gameboy sound core last night. Not sure when and if it will be finished.

rb6502 commented 8 years ago

We have an excellent PCI framework, currently used by iteagle.cpp and (minimally) by atlantis.cpp. The ES137x sound card and the 3dfx cards are available as pluggable devices thus far. We just need to emulate the PCI host, which is usually part of the south bridge.

fuel-pcbox commented 8 years ago

@rb6502 Okay, what about the ATAPI code from PCem? After all, it does work a lot better than MAME's. :^)

rb6502 commented 8 years ago

How so? MAME has disc switch support now on PC. (I recall that was your hobby-horse, anyway).

Aside from assimilating emulation related open source code, it might be useful to find and incorporate libraries that will make the whole I/O as portable as possible. Like BGFX for graphics rendering, look what's out there for audio output and generic input handling. Also VLC code can be used to add videosnap feature to new GUI (see #840). Also fs-uae is open source which could take Amiga (and related) emulation years ahead. That said, I've contacted the author and he is not interested to help (but that doesn't change the fact that the code is GPL-2.0).

Nick: " author and he is not interested to help" is that related to PCem or fs-uae ?

fs-uae.

rb6502 commented 8 years ago

If we pull from UAE, it'll be from upstream WinUAE. Toni's pretty friendly as long as we're doing the work :)

Thumbs up for Bochs CPU code. "Design and Testing of a CPU Emulator", a paper from Microsoft Research, located at http://research.microsoft.com/pubs/102035/techeport%20cpu_test%20v4.pdf suggests there are unemulated 808x quirks Bochs handles correctly (see paragraph 5.1 "When the Specs Are Wrong").

Any kind of open source & loseless video codec, that is better than our current heavyweight raw codec as option for -aviwrite or video playback.

galibert commented 8 years ago

Lagarith looked like a candidate.

OG.

@angelosa It's very handy to just use gzip. Here's an example of its implementation: http://repo.or.cz/lsnes.git/blob/HEAD:/src/video/avi/codec/video/cscd.cpp The same method if used in camstudio lossless codec. It allows gzip compression levels, not all other lossless codecs can do that.

Otherwise, here's my post with a bit more details: https://github.com/mamedev/mame/issues/1894
