What everdrive are you using?
Sounds like your everdrive is having trouble with creating or loading a save file. It's likely the wrong values are being assigned to locations in RAM and the game is crashing.
I've had this happen in the past when using corrupted save files or save files/save states that are for different versions of the same GB game (almost identical data but memory addresses might be in different locations).
I assume you have saved/loaded a saved game before this crash occurs.
You might test your ROM on a PC using BGB or SameBoy etc. To see if your everdrive is corrupting the save file?
Let me know how you go.
Cheers.
