I'm using R4SDHC with Wood R4 1.19 with dual boot. Unfotunately I keep getting an error message "Failed to write game data. Please turn off power and reinsert your game card" whenever I start up Golden Sun (U). Other games start up fine on Wood R4. I've tried YSMenu 6.41 by Retrogamefan but it just gives me a white screen. Does anyone have a possible solution to my problem. I would greatly appreciate it, thank you.
