Genesis repro cart saving issue
Post Posted: Tue Sep 15, 2020 5:22 pm
Good day guys, I've built myself a repro cart for my personnal use to test translations and homebrew games.

Its designed to support 27c322 and 27c160 eeprom and have onboard sram for saving.

I tested Sonic 3 complete (27c322) and it saves well, no issue at all.

When I tested MonsterWorld4 (27c160) it doesnt save, thats weird.

Here is my schematic, any idea why this game doesnt save well?
Thanks
