Games do not save on summercart

[jchier]

On a Summercart cartridge which uses n64-flashcart-menu, game saves disappear after reloading a rom. Trying with Zelda 2: to reproduce, get a game over. save the game. Reset the console, load the rom. No save files are present. There is a save folder which appears to have a .sav file for each rom, but these are not utilized by the emulator.
