Hi there! NDS Lite + 2015 R4, ysmenu - 20 hours into the Sacred Gold and somewhere between Ecrutak and Olivine I've encountered blackscreens on different occasions. Sometimes just after selecting save, at other times after entering building/starting a fight, going into bag/pokemon/pokedex screen. On the bottom screen some of the menu labels read "????????" instead of their tags (i.e. Pokedex or Bag).
Any idea what might be wrong? Corrupted save file or R4 card? Other games work just fine. If the save file is the problem - is there a way to repair it?
Cheers!
