I have read the files. Thanks for the welcome. and the roms are in the same folder as the emulator

Hello,
I recently got my Ti nspire cx and I need help with gbc4nspire and other emulators (nespire, and gbspnspire)
I can get the emulators fine, I have ndless. The emulators also recognize the roms perfectly, but every time I try to open a rom it goes directly back to the file screen (this is the same for all the emulators so Im begining to think thats its my fault, not theirs) I would appreciate any help offered to me.
Thanks! 


(fwi: the only game I can get to work is ndoom, and I have already tried the emulators without is, so I know that its not the problem)
