Ok... I walked into Fry's today and took a look at Ribbit King... no intention of buying it, but I was curious about the box...
Ribbit King, a $20 budget title, is a two disc game.
This is killing me. Ribbit King uses a second disc JUST for a pile of video clips. That's all. The box says it comes with a bonus disc containing movie clips of "Frolf" (frog golf).
Atomic Planet may well be the most worthless assortment of folks known to man, at this point... all signs point to two discs being a perfectly viable option, especially given that the 8 MM games are all individual programs (being ported directly from the original PSX titles)... you wouldn't even need to do any work to split the game into pieces, JUST dump 4-5 games on one disc and 4-5 games on the other.
