Running old school games on your PSP? It's definitely possible

BTW I played some more games recently, and I found that some games run faster/smoother on TempGBAMod, but some games run faster/smoother on this UO GPSP Kai, so it is good to have both emulators on your PSP, just in case.

I've been playing around with this, if someone wants to try these builds out. Ideally start afresh, and just copy over your sram, savestates, screenshots, cheats and 'gba_bios.bin' from your previous Kai build. If you do want to keep your existing Kai folder, then other than overwriting the 'Eboot.PBP', also delete the 'gpsp.cfg' from the emu root folder and overwrite the 'prx' files in it.

UO gpSP Kai v3.4 Test4 Build 230:
- Fixed regression: Analog Nub mapping works separately from Dpad again.
- Fixed regression: Now by default, GBA button 'B' is mapped to 'Cross' and GBA button 'A' is
mapped to 'Circle' to match a real GBA. The 225 build had these buttons reversed by default.
- 'Update backup' is now defaulted to 'Automatic' rather than 'Exit only'. It can still be
configured on a per game basis.

Slim build (20xx/30xx/Go(N10xx)/Street(E100x)):
gpSP Kai v3.4 test 4 build 230 (Slim)

Fat Build (10xx):
gpSP Kai v3.4 test 4 build 230 (Fat)

Update:
Use this new '230' build, not the '228' build I originally uploaded (there was a bug in keymapping). Also, if you used the 'cfg' folder from the '228' archive, replace it with the one in this '230' archive or the '225' archive (they're both the same).
Also, in addition to the 'Slim' build, the 'Fat' build is now tested as well and reported to be working fine.

This is really great, but there's a few minor problems
1. Sigma Star Saga still unable to show health bar
2. Golden Sun series, still unplayable.

If can, could you mod the TempGBA version as well? That one had more compatibility than gPSP

Was anything done to improve performance on 288 slim? I'm running it on Adrenaline and I have noticed that the screen tearing from the Mother 3 intro, and gameplay, is totally gone. I haven't tested any Pokemon roms, but this is really great.

Until retroarch can handle GBA games I'm using your 288 slim version to play the Mother series.

I updated this to '230' (link in my post above) as there was a keymapping bug in the '228' build. If you used the 'cfg' folder from the '228' archive, replace it with the one in the '230' archive or the '225' archive (they're both the same).

You're probably better off trying 'GPSP-J' of 'TempGBA-Mod' for games that have compatibility issues, as the core files of Kai are quite old. Kai is still faster on certain games though, that's why I like to keep it on my memory card along with 'GPSP-J' of 'TempGBA-Mod'. I just wanted to fix some bits in EricPshat's '225' build.
With regards to TempGBA, those changes I made are already present in it. Only 'Update backup' works slightly differently in that it is always read from the main config rather than on a per game basis.

The 'Slim' build makes use of the additional ram available on the slim units.
