    Default gpSP 0.9 - GBA Emulator for the PSP (full speed)

    - As many of you know, I'm not terribly impressed with the unofficial builds of gpSP that exist without my consent. I have a nice rant about it in the readme, most of you have probably heard me here already anyway so I won't repeat it. Suffice it to say, I'm pretty serious about what I'm going to be doing at this point.

    - This thing was way too much work. >_< I intended to release it at midnight, and I was basically about to, when my beta tester found fresh problems. So here I am, 6 hours later, now ready to release, I guess. I want to give a huge thanks to Veskgar, who stayed up all night with me to beta test.

    - Obviously not every game is going to work, still. I'd love to give you an estimate of what the compatability is like, but until I've actually confirmed that many games of ALL GBA games I'll never feel confident in anything I say. But it's higher than 0.8.

    - 0.9 still means beta. 1.0 won't be beta. If I ever release 1.0.

    I actually worked really hard on this all day to add a bunch of stuff. This is, of course, in spite of all the crap from this scene. Don't get me wrong, there are a lot of very appreciative and dedicated people around (my two beta testers, of course). But I have to deal with a lot of things. People swearing at me for refusing to give them the BIOS, for instance. One person even threatened to report me to Nintendo because I refused to send him one. People literally arguing with me about why it's not fair for me to refuse to send them ROMs. People impersonating me on other message boards. Someone recently pretended to be me and said that I was giving up because I can't compete with Takka's releases. Things like that.

    But I'll still work on this emulator. I started it for a reason and I'm going to see it through, even if I get nothing but headaches from it. I don't really play it mayself, though; I doubt anyone's going to believe me when I say that I actually do code it for the benefit of other people. No matter what, I still remember what it was like when I was 13 and emulators were very important to me, where a new one could make a dramatic difference in my life. Sad as that sounds. If I can be helpful to anyone I want to be.

    But that won't really stop me from being possessive of my emulator. I want it to be developed the way I prefer - fortunately, I happen to sincerely think that I know what's best for it too.

    Anyway, I've rambled enough. No, I won't post what's new here, go read the readme. Have fun :P

    The source. Don't take it for granted, because it might not be there next time.
    Heres whats New for those interested
    • # 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.

    This is the best emulator on PSP... so far.
    Let's hope for all others to be as good as this one.

    Does this emulator work on 4.01 m33-2?

    I've tried a few different combinations and I can't seem to get it to work. I get an error message when I try to run the emulator. And yes, I did acquire a GBA.bios file. And yes, I did follow the ReadMe.

    I tried the normal GAME Folder. I tried a GAME150 folder. Nothing.

    this emulator is the best one. I;m currently using this one and I have no problems with it whatsoever except for the CHT files.
