Key Mapping

the < key is mapped to SELECT and the ||| key is mapped to START.






What's the keymapping? I can get it to load NES ROMs but I can't seem to push SELECT or START to actually start the game.

Hi, the < key is mapped to SELECT and the ||| key is mapped to START.



I follow all the instructions, convert the file, drag it to the Xtron, and reset, but whenever I choose the new file from the list inside the emulator, it just loads a blank white screen. What am I doing wrong?

Hi, Please make sure that the size of your ROM is less than 256KB.
