I don't think the SFII games needed that much cart space if they compressed some of those graphics. Resulting in SFII WW costing me 115 Canadian dollars brand new when it came out being total bull for a kid without any income. Because last I heard here, these Capcom games don't compress the background graphics at all. So imagine how much better it could of been with that extra cart space saved... (or money saved)
But, this raises another question. Why did Capcom not compress the background graphics in SFII? What shortcoming on Capcoms programming skills did this cover?
