I made a few tests and realized that EEPROM save games are working but I used the reset and they are still not saving.

Games tested:
NBA Jam (not yet saved)
NBA Jam T.E. (working but not saved)
NBA Jam Tournament Edition32X (working but not saved)
College Slam (working but not saved)
NBA Hang Time (Create Player does not work)
NFL Quaterback Club32X (not working)

The tests I did with the RESET TO MENU: OFF
These EEPROM saves work only with RESET TO MENU: ON?

You should enable reset to menu. At startup OS copying data from internal fpga memory to nonvolatile memory. If you turn off reset to menu, OS does not boot and all data stay in internal fpga memory and you lost it after power cycle

I just figured EEPROM saving was already a feature!  Ha ha, great addition Krikzz.

i activated the RESET TO MENU option and it worked! But I have some questions.
1-Do you have any possibility to have a new update that does not need to activate the RESET TO MENU to save EEPROM?
2-Does NBA Hang Time use EEPROM or other type of save?

Thanks for the new update! I've been waiting for it for a long time😀

1. There is no technical possibility to make it work without reset. May be later some great idea will come in my head, and i will make it work without reset, but for now this is all what i can offer.
2. all eeprom games listed here: https://krikzz.com/pub/support/everdrive-md/v2/gen_eeprom.pdf  NBA hang not one of them, as i can see

I think the NBA HANG TiME does not use EEPROM. Maybe the FERAM (the same used in Sonic3) or SRAM.
I started to create a player, put the name and PiN created the player and saved it, but when it comes to play and puts the name and created PiN does not enter (as if it had not saved).

Hmm. I tried this last night with Mega Man Wily Wars. Didn't work.

I unzipped the file, and click-dragged the contents into the MEGA folder on the SD card. That should suffice, right?

You should replace MEGA.BIN and MEGA.RBF

My Everdrive requires a MEGAOS.BIN and renaming MEGA.BIN doesn't work.

I installed the new software.  I completely deleted the old MEGA folder, and then copied in the new MEGA folder. 

I assume I have a Mega7v2, as it was manufactured in 2016.   But the NBA Jam saves aren't working for me.  I do have reset to menu ON.  When I hit reset, and then hit start to go back into the game, the record that was just saved is gone.     Thoughts? 

Edit: Also, I *see* saved .eep data when viewing on a computer.  But again, when I'm in the game, and go to saved records in the game (NBA Jam) there is nothing.  Is there some sort of load .eep function that I need to do?

I did some tests in some games and I noticed the following.
NBA Jam >>> Saves in MEGA folder but does not show in game
NBA Jam T.E. >>> OK
NBA Jam Tournament Edition 32X >>> OK
College Slam >>> OK

The NBA Jam I use is REV 01 (V1.1), is that why it's not showing the save in the game?
