Save bug with Smart Card GB USB 64M
by on (#167909)
Hello everybody,
I recently bought a smart card GB USB 64M especially to use the chiptune tracker LSDJ. So I put on one side LSDJ and on the other side some games (Kirby's dream land 1 & 2, Link's Awakening, Zelda Oracle of Seasons). But every time I save a game, the saving dissapears, even if I do it only with one of these games. I tried also the technique explained on Hard+Soft Gaming (https://hardandsoftgaming.wordpress.com ... ption-fix/) but it's still impossible to save.
Does anybody have an idea of what to do?

Thanks
