What's the most recent version of it anyway? gPSP? gPSP Kai?

I found the sources to gPSP v 0.9. According to the included read me, any distribution with anything else other than gPSP in the title are unsupported by the original author (unless they are just system ports).

The source is here: http://dl.qj.net/psp/emulators/gpsp-09-source.html

If someone wants to start a repo for it, we could start making changes here and there to get it compiling with the SDK if we can't obtain the supercard sources.

That's awfully old (2006), and it looks like a version the Supercard team would have used. Then again, I took a stroll to the PSP section on GBAtemp, via Google, and they talk about gPSP-J 2012-06-16 [Ed Note: Emphasis mine]:
Rydian - actually I think performance and "processing hacks" are the main updates made for gpSP, since the support decreased yet the performance increased... well we didn't expect full emulation, hell full SNES emulation on PC requires a PC above average GAMING PC, so PSP shouldn't hit the full GBA emulation, even though it's PSP, maybe Vita might... doublty
This doesn't bode well. Go with old, slow and compatible? or new, fast and glitched?

Could have 2 branches I suppose. Any changes we make for one could probably be put to use in the other one. Might be better off starting with the old stable one for the sake maintaining NDSGBA compatibility.

People that do GBA emulation on the PSP deal with either Kai or -J anyways so there's another split, though Idunno' if both sources are available.
There is some source for gPSP Kai on SourceForge Japan, updated 2010-04-16: http://en.sourceforge.jp/projects/gpsp-kai/scm/svn/

There is this announcement where "the anonymous Japanese coder" is credited for a new release of gPSP-J on 2012-06-16, but no source code that I could find using the query "gPSP-J 20120616 source code": http://www.emucr.com/2012/06/gpsp-j-20120616.html

Why not just start demanding the NDSGBA source from the SC team/their contact right now?

The new CATSFC has almost all the new improvements NDSGBA needs and unlike CATSFC NDSGBA runs most games at perfect or near perfect speed. No need to reinvent the wheel if we don't have to.

Point is that we do. No one, being Normmatt or the Supercard Team, seems willing to release the source.

Well, they're legally obligated to. Just spam the hell out of them until they give it up if its like that. Give me their contact email and I'll personally ask.

"Legally obligated" mixed with China.

Yeah, good luck with that one.




No seriously, China in general doesn't give two shits about copyright/IP. You'll even find links to ROM sites, and ROMs themselves, on the sites of some R4 clones (and shops will sell carts preloaded with ROMs).

It's not even a legal issue, if/once we get in direct contact with them they should know that it's in their best interest to have higher quality software running on the hardware they're selling. It's well known now that the DSTWO's SNES emulator was unplayable crap but recently Nebuleon has been making serious changes to that. It would do them good to fix up their mediocre GBA emulator too, they have literally no reason to keep the source to themselves (especially since they're not even doing anything to it) and by offering to keep it up to date and making improvements we're doing them a favor.

I think this aspect would matter more to a Chinese company, indeed. The "you're gonna get more sales if your product is better" aspect.

NDSGBA version 1.21 supports a game_config.txt file to be put in the NDSGBA folder which fixes quite some games, like pokemon and such, because it corrects the save size type to the right one or something like that and fixes other useful things.
Anyways, it boosts the game compatibility considerably.

Here's his thread: http://gbatemp.net/threads/iplayer-supercard-gbaemu-game_config-txt-improvement-project.248619/

Here's the latest game_config.txt: http://filetrip.net/nds-downloads/f...iplayer-gba-emu-gameconfigtxt-v13-f12630.html
