Hello everyone, please, I need help to identify the roms that contain the maincpu of this PCB, is a hack of Street Fighter, 2 CE MSTREET-6, this PCB has two Eprom M5M27C102K-15 just below the Jamma connector mounted one on top of the other, the size of each is 131072 Bytes that are supposed to contain maincpu data, from these two Eprom mounted one on top of the other, some cables go soldered to another socket in which two PAL one on top of the other mounted, and then next to the long Motorola processor there are two sockets that say u10 and u196 with memories, I have asked ChatGPT and he tells me that they are DRAM and that it is impossible that there are maincpu rom data, in the u10 socket there is a KM418C256J-80 memory with 512kb of data and in the u196 socket there is a memory KM418C256J-70 with 1024kb of data, could someone tell me if these sockets and said memories have maincpu data and are not really DRAM? Also investigating my PCB, in the bottom part where the mask roms usually go, there are memories with very similar references, in which only one number changes: KM418C256J, could it be that all these supposed DRAM are not? because if only the two eproms mounted on top of each other had maincpu data, I think that is little data for the game and I think that more is missing, I have looked on the web at the mstreet-6 versions to see what the memories of the u10 and u196 sockets contain and each one of them matches in size (ms6.u10 / ms6.u196), it is a version that is not dumped in mame and I would like to preserve it, I attach photos, thanks and greetings.
