I've never been able to get EEPROM saving to work for the original NBA Jam, on my MegaEDX7 since the announcement was made over 2 yrs ago that this functionality was added. NBA Jam Tournament Edition, no problem.
My curiosity was piqued today when I saw a post on Romhacking of a patch that allowed standard SRAM saving. That didn't work for me either.
So, can anyone successfully save data on the original NBA Jam after resetting or powering off the system, and if so, could you tell me exactly what steps you take, what hardware you have, what version of the game, and what version of MegaED OS you are running?
I've tried 3.06, 3.11, and 3.13. And I'm running on a MegaSg console.
