Sega games with extra chips, special components or mappers
« on: September 13, 2019, 05:57 PM »
It's not as common for Sega games to have weird mappers or special chips like Nintendo had on NES and SNES... But apparently there are a few...

The most well known is Virtua Racing on Sega Genesis which had its own special chip to help with the 3D effects.

Another is Phantasy Star Fukkoban? Which apparently had an "SMS" chip/mapper on the board, though the game itself was original SMS final fantasy stuck in a Genesis cartridge.

On the GameGear side there were like 10-12 games that were simply SMS roms stuffed on a GameGear cartridge with a special chip/extra components ("Master Gear") and utilized a special mode/resolution/colors on the system to compress the resolution down to what GG could handle.

Maybe some of the unlicensed games used their own mappers too?

Anyone have a full list of the more unique Sega games that used special chips or mappers?

There isn't much else that I'm aware of. Sonic & Knuckles had an extra ROM chip in it for running Knuckles in Sonic 2; there were a half-dozen carts that had extra controller ports built in (Pete Sampras Tennis, Pete Sampras Tennis 96, Micro Machines 2, Micro Machines 96, Micro Machines Military Edition, and Super Skidmarks); and a couple games used bank switching to get around the 4MB ROM limitation (Super Street Fighter II, Pier Solar, and Paprium, if it were ever to be released). You can find most of that info here:
