When I play certain games on my R4DS such as Drawn to Life, Heroes of Mana, or MegaMan Star Force: Dragon/Leo/Pegasus I receive an error message that looks like this: Could not read data. Please turn power off and reinsert game cartridge. This does not happen for all games so I don't know what to do to fix the problem. I searched the internet for similar cases and found out that this problem occurs for the same NDS games in No$gba, and that the problem there can be fixed by changing the cartridge back-up media to FLASH 256 Kb or FLASH 512 Kb. However, I don't know how I can fix this problem with my R4DS. Does anyone know what I need to do so that I can get these games to work? I searched these forums and could not find a similar thread, but if there was one that I happened to over look I sincerely apologize.
