Hi
Yeah when i first started off with 1200 upgrades i also came across many problems inc blown motherboards,power flyers and roms...So a lot of this was mistakes along the way and others not my fault.But yeah when you plug the roms in the wrong way they ususaly seem to go very hot within seconds.So chances are you might of just blown them because i also made that mistake..Just be careful with the powerflyer because they can be a right pain esp if you end up bending the pins on the board.Plus if you have a d-box aswell as the other upgrades you should still finish off your 1200 regardless if you have blown the motherboard as they are easy enough to find...
