    Can you give us some details about the bios: region, revision, differences...
    Also about alt game revisions: is there anything beside P roms that can change gameplay between 2 revisions of the same game?

    I have not done advanced testing, but I see that sengoku3 has a neogeo jingle fix, world heros 2 is a newer game build that the one in MAME. The bios are U3 and J3.

    Ack has confirmed a NGP dumper can correctly dump the NeoGeo Pocket type PCB's used on a few NeoGeo games from 1999/2000.

    Games known to use this daughter PCB on some carts so far are; KOF2000, Garou and Metal Slug 3.

    The mini PCB must be removed from the PROG board before dumping and both sides must be read (flip if over in NGP reader). The resulting two dump are then simply interleaved (8bit). This process has been done on both KOF2000 and Garou. Both dumps once interleaved match dumps already in MAME (when the matching encrypted P1 and P2 are simply joined P1+P2). There is no new encryption or different syle of encryption used.

    Now its just a case of getting the Metal Slug 3 known to be different and uses a NGP style daughter into the right hands.

    Was there any correlation between the already dumped MS3s and the serial numbers they had or is it completely arbitrary?

    edit: just remembered many MVS carts have the serials removed so its probably not the best question to ask.

    Yes, the p1 was dumped with PC-2-NEO. The issue is the owner does not want to have the chips removed to dump the rest (which S is needed, probably M also and maybe V and C). Until those are dumped the game is not playable really.

    gotcha, thanks, too bad a "non-invasive" dumper device project didn't get much attention from the community

    Ok so the MS3 cart with the daughter board is out the door & on it's way to ack. He should be getting it in 2-3 days. I'm interested to know if this revision has any major changes from the regular version. It's probably just a bugfix, but it would be great to find this cart was special.

    First post updated (thanks rot). The new MS3 dump is an earlier revision of the game. The later version (already in MAME) has 0x08 bytes inserted at 0x043874, it checks to see if a player is playing and skips some code if they are.
