For those two games specifically, it's possibly software copy detection. SNES cart copiers would usually have 32kB SRAM, and some games check for that. Later copiers I believe limited RAM size or something to bypass it, but SimCity 2000 was a game I specifically remember cracking the protection in it myself because it didn't work on the Game Doctor SF7 (and ucon64 didn't seem to have a patch for it).soniccd123 wrote: ↑Fri Jul 10, 2020 5:21 pm The games work normally, i've tried SC2000 and DK Country, but are not saving, the memory OE is connected to CART_RD and WR is connected to CART_WR.
edit: or maybe not, on re-reading it sounds like they play normally, but just don't save?
