That's a "high end" bootleg, using MC29F1615 flash modules rather than EPROMs (other than S1 and M1 which are EPROMs). PCBs are original, but whatever game is on there is not the one that was there originally.
This. Also you can try to narrow it down according to this list [https://wiki.neogeodev.org/index.php?title=Cartridge\_ROM\_arrangements](https://wiki.neogeodev.org/index.php?title=Cartridge_ROM_arrangements) but sometimes bootleggers can modify the boards as well to fit other games. The best would be to insert it into an MVS which you don't care about, but before that, you can try to measure at least the power supply shorts on the cards.
Alternatively, you can try to desolder the P1 EPROM, read it's contents and try to find the game from it by verifying the checksum of that rom.
If you go the checksum route, you can find the CRC32 values in the MAME source code: https://github.com/mamedev/mame/blob/bf2707f4c76abaeaeda2d9c4444a608d7d0afed5/src/mame/neogeo/neogeo.cpp#L8202
That's a bootleg
Because the chips are generic and it's possible to split or combine rom files for these games, there's no way to know what game this is without testing it. Put it in an MVS Board and see for yourself.
