Core running the game 20240827_053140-SNK Vs Capcom - Match of The Millennium (JUE) !

Core simulating the scene from a video RAM dump frame_00002

The game uses two flash memories. Second flash support is missing in the core. Adding it next.

jotego commented 4 weeks ago

Game did not start in simulation because the RAM slot erasing was enabled. This must have been the reason why selecting a cartridge when starting the core stopped working on the Analogue Pocket. RAM slot erasing disabled in f2567ba5. Game boots up now in simulation too.

Data correctly read from flash1 in 11b77505, but it is not well written during the cartridge load. cart_addr in flash 1 is stuck at zero.
