Just bought one 2 weeks ago. It's awesome !! Was trying to play Sonic 3 and Knuckles, as well as Knuckles Chaotix with Mega Everdrive on my US Genesis Model 2 with 32X. For Sonic 3, i just got the first Chaos Emerald. Once i got back to Act 1, i reset my system to get it to save (Trying to get it to save like it would like a normal cartridge, not save states). Once i was at the menu and selected my game again, it didn't save my progress. Same with Knuckles Chaotix after beating the first level. Am i doing anything wrong ? Was i suppose to enable something before hand ? Please help. Thank you.
