I have a Genius G540, and the damned thing does jack. It will read a chip, but it refuses to program anything: I select a chip (SST 39VF010), drop it in the adapter, load a file to burn to it (A Pro Action Replay mk3 rom), and press 'program'...and all I get is "ProgramError". There's no help file aside from an Engrish manual that is more about installing the software itself. Would you mind explaining how you got your G540 to do more than blink and waste time?
