Thanks for confirming also having problems with NBA Jam specifically. I hadn't tried any other games because NBA Jam was my top priority.

 Krikzz, any suggestions on the problem?  Needs a certain ROM version maybe?

This game needs a patch in order to work. The patch can be downloaded here: http://krikzz.com/forum/index.php?topic=3086.0

This patch that makes the game work affects the save function.

NFL Quarterback Club 32X: Probably i did not include this game to eeprom games list. You can check in "Rom config" menu if this game forced to use eeprom
The NBA Jam: This game have bug in save code, only ROM v1.1 has fixed code and can save properly

Here's my Everdrive information:
MegaEDx7
Model 15
OS 3.06
System US NTSC 60S
Assembled Jan 2016
Firmware 1
Reset to menu: on
In game menu: on
Game Region: US NTSC

ROM: NBA Jam (USA,Europe) (V 1.1).md

Plays through game in NBA Jam, initials are saved, go into NBA Jam's options menu and confirm that the initials are saved.   Resets game.  Re-opens NBA Jam (USA,Europe)(V 1.1).md ROM.  Initials are no longer saved.     What could be wrong?

Are you sure that options values should be saved? Try it on some emulator with eeprom supports, on Fusion, for example. I just tried on emulator and it does not save options. May be game programmed to save game progress, but not options. Those old eeproms has limited rewrite count, so programmers could skip options saving to protect eeprom.

This is how the game works as a cartridge---- you enter your initials, you play through a game, and it saves your win-loss record for the initials.  On the Everdrive, with everything I've tried, it's not worked this way. 

I just played through a game on Fusion (Using the 1.1 ROM) and had my initials saved, and then reloaded the game to see if the eeprom saves worked. It worked.  After playing a game and having my initials saved, I tried:

soft reset: Worked. Initials save still there.
Hard rest/power on: Worked. Initials save still there.
Close Fusion and re-open fusion, reload the ROM: Worked. Initials save still there.
