You sir are a scholar and a gentleman, that fixed the issue.
fat16 32kb and now it works everywhere!
Edit: Also it would seem this also fixed the weird slowdowns and laggy menu I have been having.
What program have you used to change your microSD into FAT16 and 32kb?
Al the programs I found don't let me choice FAT16 and 32kb, only let me choice FAT16 64kb
I'm in the same problem as you, it's sooo maddening
I copypaste you my original post, I hope you can help me xD
I have put Opendingux, the computer recognizes the console, I have put the emulators for the RS90 in its APPS folder and so far, it recognizes the emulators, but the problem comes with the microSD, I put the roms in their corresponding folders (GB, GBA, SNES, etc) and when I put it in the RS90 and enter the GBA emulator to play Castlevania Circle of the Moon, I did not get the game or the rest either or anything. I get this specifically: a folder called "data", I enter and there are other folders that do not lead me anywhere, I am quite a noob on the subject, it is the first console of this style that I venture to flash, and now I find myself frustrated in front of to what I think is going to be a brick that I will not be able to use
A little help !!!
Sorry for my terrible english, i'm foreign xD
