Yes I beleive you can fry things.
The roms should be inserted with the space on the left.
The motherboard has a nice white painted arrow on it telling you to do so. The notch on the IC also points to the left.
Note: swapping the roms will not fry anything but inserting them the wrong way; eg 180 degree rotated (notch to the right) or spare pins to the right may fry the roms.
Also make sure you are discharged before handling semiconductors. Grab the radiator or better use an anti static wrist band. I blew Roms once by just touching.
And all the information I just wrote is by head so can anyone confirm this. I dont want to be the cause of someones blown roms
