Wow sounds like you had/having problems with your n900. i have been lucky, this is my 2nd n900 the 1st one the usb connector broke so i had to send it back and they replaced it with a new one and never had to refash any of them.

Sounds like your a retro gamer like myself i wish someone out there would attempt to port an old version of mame i am confident it would run better than FBA.

i have requested this many times and still no joy its getting to the point where i may have to start begging.
