Stunt Race FX on the SNES i believe used two of the SuperFX chips... but someone here may correct me on that.


Edit: Butchered the title of the game...

Mario Kart used a math coprocessor.

Yep!

I've no clue what the chips inside the Phantasy Star re-release on Mega Drive are, but apparently there's some emulation going on in there...maybe. That's one of life's great mysteries, for me. Cart didn't feel heavier than normal (but it's been months since I checked).

This is From Wikipedia, http://en.wikipedia.org/wiki/Super_FX_Chip



Games that used the Super FX chip

* Star Fox
* Stunt Race FX

Games that used the Super FX2 chip

* Dirt Racer
* Dirt Trax FX
* Doom
* FX Fighter (unreleased)
* Star Fox 2 (unreleased)
* Super Mario World 2: Yoshi's Island
* Vortex
* Winter Gold



If you look on the bottom of the Doom cartridge, and Mario Kart, they have a larger edge connector than normal games. And also a metal tab on one side of the cart.


This is from:

The DSP chip is a chip that helps the SNES to handle more advanced 3D effect in mode 7, than it can handle normally. DSP stand for Digital Signal Processor.

Armored Trooper Votoms, Ballz, F1 ROC II, PilotWings, Super Mario Kart, Super Air Diver, and Dungeon Master.

The DSP 2 chip

The first game to have the chip built in was Seta´s own F1 Race of Champions it was later also used in the Japan game Ace no Nerae (Aim for the Ace) and Top Gear 3000 from Kemco.


Theres a few other chips listed on that site. But, wasn't there also a SNES cartridge that had it's own sound chip, too? CAn't find it on google..[/quote]

Not thinking of the tons of NES memory mappers, right? Everybody had custom mappers/sound chips.

It's just the same little IC that's in the PBC, which forces the Genesis into SMS mode. The rom itself is simply SMS Phantasy Star. In essence, what you have is PS + PBC on a cart.

My Mario Kart game isn't any different than a normal game (it's the million seller or whatever does that make a difference?), but I do know for sure my Kirby Superstar and Street Fighter Alpha 2 have longer pins and the metal tab on the side of the cart.

@ Wavelflack
Hmm. As damned big as the PBC is, I wouldn't have guessed...ah well, I shouldn't want it any other way. :P

Which, since it's the Japanese version, also has an FM chip in it.

Huh, never had thought about that. Will check that out for sure.

I believe Mega Man X2 also used a chip similar to the DSP Chip.

Every snes game using a special chip is listed here:

Ummm...are you sure? I think I remember hearing they did not include the FM sound on this one. I own the cart and I don't think I ever noticed anythink different than the SMS version. <shrugs>

I'm not sure any of those would be considered coprocessors. I could be wrong, but weren't most of them often just added logic gates of some sort? I dunno...fill me in.
