yeah i was aware why you had the issues, but it could still be the root cause of the issues here.....then again it might be unrelated, but no harm tryingAll I meant was that if you played the EUR rom, then tried the USA rom (as I did). The USA one might not load the save because it will be confused about which "extra data" to load. This has nothing to do with save conversions. Sorry.
he is trying to switch the rom region after all XD
