    BIOS and Header fixed atomiswave converts

    I added an unlocked version of Neo Geo Battle Coliseum, to unlock all characters the system region must be changed to "other" and language to "english" in the test menu, most characters remain locked if the region is set to Japan. Thanks to YZB for this patch.

    I am not quite sure what causes it, it seems that the original value triggers an exception (I assume from accessing an illegal/unmapped range); I got the value (0xFEAC) from the final revision of the DC conversion and tested to make sure it works on the NAOMI.

    The rom needed to be patched rather than the loader. Value 0x20A0 needs to be changed to 0xFEAC at locations 0xB51BE and 0xBA57E in the naomi rom (though only patching location 0xBA57E is enough to fix the bug)

    I just added aw-knights_of_valour_the_7_spirits_Dubhe_Unlocked_AW03 to the mix, it's a patched version that unlocks Dubhe directly without the need to input any cheats or finish the game once.

    I just added a aw-violent_metal_slug_6_DBG_AW08 rom which enables the debugger (and allows to pause the game), assuming your buttons are mapped properly. On OpenJVS that's button 4 and 5 player 1 (L3 + Square on a ps3 controller on the generic profile)

    Atomiswave Metal slug 6 ported to Dreamcast!!

    I kinda wonder, wouldn't it work using a mapple controller if we remove the JVS part from the AW loader? (assuming we patch games to run in freeplay mode)?

    Does this happen on the original convert with an older bios? (rev B or G), I strongly suspect it does, I messed with the loader part on it and still got the error, it seems likely to be a rom issue (the rom was probably not mean to run in "North America' region, it was probably just sold as...

    I found a bug in guilty gear isuka, the game black screens after losing. I have attempted to fix this without much success, I strongly suspect this happens on the original converts too, can someone check (you need to be on B/G bios to run the original convert). I changed the AW loader part...

    BIOS and Header fixed atomiswave converts

    I managed to replicate this and get error 22 after the title screen on the North America region. I would say that if you want the game in English just keep it on the Japan region and set the language to English instead, there is no need to change the region, that said, after investigating...

    In case you are wondering, the Sega Bass and Sega Clay converts only run on DEMUL but not on real hardware (even the original files). There are also 2 more games missing, which are Force Five (AW18) and Kenju (AW23) which are tested and do run but I have been asked not to share those on AP as...
