This'll be cool to see when it's done. I wish I owned more FDS games, so I could help.

You can basically tell by looking for games that have a 64Kb filesize. Analyze the FDS dumps.

[DevIancE]

That's a good idea. Thanks.

[nintendodork]

Pac-Man.

[Medisinyl]

Mahjong (I had one with Zanac written on the back). 

[namzep]

I'm pretty sure you can add:

Galaga
Dig Dug 2
Xevious

As I have all three on disk writer disks with stuff on the other side.

[ckenda1]

Galaxian
Ice Hockey
Pinball
Goonies
Solomon no Kagi
Dig Dug 2 (like mentioned above)
Twinbee
Soccer

I'll list more as I think of more.  I got a ton of games at home.

[ckenda1]

Bomberman
Pachicom
Hong Kong (Famimaga Disk Vol. 1)
All One (Famimaga Disk Vol. 3)
Clox (Famimaga Disk Vol. 4)

[FamicomFreak]

Wow this list is growing a lot. Keep them coming!

[UglyJoe]

We could probably just take a look at an FDS rom list in order to figure this out.  Any fds file that is 64kb will fit on a single side.

[Blue Protoman]

Go onto some torrent place and download the whole FDS ROM set.  Then, arrange them by size and the rest is easy.

[UglyJoe]

Yes, that's pretty much exactly what I just said.

[JC]

OK, so somebody get to it.

Not sure if my set is complete (and I'm too lazy to audit and/or redownload it), but here's the 65516 byte games I've got:
