Secret 33:
The largest HuCard is 8 MegaBits. Except for Street Fighter 2, which was 20, an absolutely enormous at the time. By comparison, the MegaDrive/Genesis version of the same game was only 16 MegaBits. The PC Engine version was the best home version of Street Fighter Champion Edition until the SNES' Super Street Fighter 2 was released years later.
OK, I'll guess:
"an absolutely enormous at the time." --> missing a noun after 'enormous.'
"Street Fighter Champion Edition" --> That would be like a game where you could play as Birdie, Adon, Gen, etc.
(Should be SFII, Champion Edition)
"best home version of SFIICE... until the SNES' Super Street Fighter 2" --> Super SFII is not a version of SFIICE; it's a version of Super SFII.
These are just a couple of niggles. Is there anything more serious you're pointing to?
