Riporto questa release della versione non ufficiale di gpSP con supporto multiplayer tramite Kai. Questo progetto non ufficiale è portato avanti da:

Exophase: main developer
siberianSTAR: zip support
psp298: analog nub code

Questa versione non è stata pubblicizzata su altri siti perchè il programmatore del progetto originale da cui deriva questa versione non è molto contento della concorrenza.

Ringrazio Leric che mi ha segnalato questa versione, che sembra migliorare molti aspetti dell'emulazione GBA su PSP.

Vi lascio al succoso changelog:


# Fixed stereo output being reversed.
# Fixed a bug causing misaligned errors on 8bit writes to the gbc
audio channel 3 wave data (fixes various Super Robot Wars games)
# Fixed DMA with garbage in their upper 4 bits (fixes a crash in
Zelda: Minish Cap)
# Added double buffering to the rendering, removes line artifacts.
Big thanks to Brunni for the idea.
# Fixed a bug preventing some SRAM based games from saving (fixes
MMBN4-6)
# Fixed a bug causing part of EWRAM to potentially get corrupted if
code segments loaded in EWRAM cross 32KB boundaries (fixes
Phantasy Star 2)
# Fixed a bug causing games using movs pc in user mode (very bad
behavior) to crash. Fixes Colin McRae Rally 2.0.
# Improved timing a bit more. Fixes GTA Advance.
# Fixed a sprite clipping bug (fixes crash in third boss of Zelda:
Minish cap)
# Increased translation buffer size significantly (fixes Donkey Kong:
King of Swing)
# Fixed a dynarec bug causing add pc, reg to not work in Thumb code
(fixes crash in DBZ:LoZ, seems to fix crashes in battle in Golden
Sun, probably fixes other games)
# Made sprites using tiles < 512 not display in modes 3-5 (fixes
a couple minor graphical bugs)
# Removed abort on instruction 0x00000000 hack, was breaking a
certain bugged up game (Scurge)
# Fixed bug in flags generating variable logical shifts (fixes
SD Gundam Force)
# Fixed unaligned 16bit reads (fixes DBZ:LoZ in game)
# Redid contiguous block flag modification checking AGAIN and
hopefully got it right this time (fixes Mario vs. Donkey Kong)
# Redid ldm/stm instructions, fixing some cases (along with the
timing improvements fixes Mario & Luigi)
# Fixed 14bit EEPROM addressing (hopefully fixes saving in a lot
of games)
# Completely redid memory handlers, accurately emulates open and
BIOS reads now. Fixes Zelda: Minish Cap (roll bug, last dungeon),
Rayman, MMBN 1 (last dungeon), probably others.
# Fixed a minor graphical glitch on the edges of the screen
(thanks Brunni and hlide for the help!)
# Fixed crash on loading savestates from files of games not currently
loaded, but be sure you have the exact file you loaded it from or
gpSP will exit.
@ New memory handlers should provide performance boost for games
that access VRAM significantly (ie 3D games)
@ Added dead flag elimination checking for logical shifts, probably
doesn't make a noticeable difference but should have been there
anyway.
+ Added rapidfire to the button mappings.
+ Added auto frameskip. Removed fractional frameskip (don't think
it's very useful with auto anyway). Select auto in the graphics/
sound menu to activate it; frameskip value will act as the
maximum (auto is by default on). Thanks again to Brunni for some
help with this. Frameskip options are game specific.
+ Added vsync to the rendering. Only occurs when frames aren't
skipped. Seems to reduce tearing at least some of the time.
+ Added non-filtered video option.
+ Cheat support (Gameshark/Pro Action Replay v1-v3 only), still
in early stages, doesn't support everything; codes may cause
the game to crash, haven't determined yet if the codes are bad
or the implementation is. See cheat section for more information.
+ Added ability to change audio buffer size. Does not take affect
until you restart the game.
+ Added analog config options.
+ Added ability to set analog sensitivity and turn off analog.
+ Added ability to change the clock speed. This is a game specific
option. Try lower speeds w/auto frameskip to save battery life.
+ Fixed savestate speed on crappy Sony sticks.
