The poll has had 80 responses so I thought I'd sort them for all to see. You'll notice ones like Megadrive/Genesis have both their combined total and their individual totals. I think this is good info to have.
Unsurprisingly, SNES, NES, PSX and Megadrive/Genesis are at the top of the list.

Edit: I just realised SNES/Super Famicom has 81 points, even though there have only been 80 entries. I guess a few someones out there have their SNES and Super Famicom Roms separate.
