snes enhancement chips = total rip off
In know that Star Fox uses the FX chip for the polygons, Yoshi's Island for the scaling and rotation special effects, and Doom uses it for it's first person view, but other than that, I can't find anything special about any of the other games that use enhancement chips.
Take for instance the SA-1 chip. From the information I've read it's a 10Mhz 65816 with features such as decompression and a better DMA. That sounds pretty good, but look at the games that use it.
First there is Super Mario RPG. It uses turn based battle. Yeah sure like you need 10Mhz to calculate AI when it is turn based? It has prerendered graphics, but so does Donkey Kong Country, and that doesn't use a chip. Nothing looks any special here.
Then there is Kirby Super Star and Kirby's Dreamland 3. They're both platformers like 100 other games on the system. Neither of them have any kind of special animation or an unusually high amount of sprites onscreen. They're just platformers.
Some people act like they can tell the difference. I don't know if they really can tell a difference or are they just assuming they have a difference just because it has a chip. What do these games do that couldn't be done without the chips? They look like your normal Snes games to me.
