I have been using R4DS for a while, recently I updated the firmware to YSMenu made from YSMenu0903270000 and Unofficial DSTT Kernel V1.17a12, I could play "Mario & Luigi: Bowsers Inside Story" without any problem. One nice feature of YSmenu is to play GBA games, following recommendations from this forum I bought an EZ Flash 3-in-1 from dealextreme, link is http://www.dealextreme.com/details.dx/sku.2967 I put Pokemon Emerald, Leaf Greed and Fire Red GBA roms on R4DS, then tried to load them with EZ Flash 3-in-1 card inserted. I got the following problems 1. Pokemon Emerald, stuck at white screen after Game Boy banner. 2. Pokemon Leaf Greed and Fire Red, games can be loaded, then got a warning of "1M sub-circuit board is not installed". When I tried to save games, I got "SAVE Error" Could you please suggest what I did is wrong? Do I need any other software to initialize EZ Flash 3-in-1? Thank you very much.
