Ahhh, I see someone is filling out their OPL library.
Anything from the Sega Ages 2500 Series, some of which are just 3D remakes of old Genesis games (Like Golden Axe or Gain Ground). I bet your not super interested in the ones that are just ports of Saturn, Arcade, and Genesis games (though, playing on PS2 is not the worst decision in the world), so, I'll just list ones that are full on remakes (semi exclusive, though, a number of them also went to the PSP as well):
- Golden Axe (149 Mb)
- Alien Syndrome (218 Mb)
- Outrun (423 Mb)
- Afterburner II (209 Mb)
- Space Harrier (not the Space Harrier collection, those are just ports) (236 Mb)
- Phantasy Star: Generation 1 (remake of Phantasy Star I) (66.6 Mb, file size of the beast)
- Phantasy Star: Generation 2 (remake of Phantasy Star II) (102 Mb)
I know we're all emulating stuff around here, but the Sega Ages series also includes a number of bangers from their vault, such as Dragon Force, Panzer Dragoon, Fighting Vipers, Dynamite Deka, Galaxy Force II, and Virtual-On. These ones are just straight ports, so I doubt their file size delineates to far from their source.
And since you mentiones Street Fighter Ex, there is also a port of Street Fighter III: Third Strike that was released for the PS2 in Japan, that's basically like the Dreamcast release. However, it became packaged in the Street Fighter Anniversary collection in the west, and that's one of the 4 gb ones, so I'd imagine the solo release is way smaller.
