Can't list them all as there are far too many.
An estimate on numbers:
NES : Didn't own it but did play on one at least.
SNES : About 15-20
N64 : About 25-30
GC : About 35-40
Wii : About 70-75
WiiU : Abount 15 or so
GB : About 15-20
GBA : About 15-20
DS : About 55-60
3DS : About 20 or so
Was gaming well before all this BTW.
Pong and Acorn Electron FTW!
