Let'z play Super FX 2 games: Super Mario World 2 - Yoshis Island

The Super FX is a coprocessor chip used in select Super Nintendo Entertainment System (SNES) video game cartridges. This custom-made RISC processor was typically programmed to act like a graphics accelerator chip that would draw polygons to a frame buffer in the RAM that sat adjacent to it. For those games, the data in this frame buffer was periodically transferred to the main video memory inside of the console using DMA in order to show up on the television display.

The first version of the chip, GSU-1, commonly called the Super FX, is clocked with a 21 MHz signal, but an internal clock speed divider halved it to 10.5 MHz. Some early cartridges of StarFox shipped with a version of this chip that was marked "MARIO Chip 1." Later on, the design was revised to become the GSU-2, known as the Super FX 2. Unlike earlier chips, this version was able to reach 21 MHz.

All versions of the Super FX chip are functionally compatible in terms of their instruction set. The differences arise in how they are packaged, their pinout, and their internal clock speed. As a result of changing the package when creating the GSU-2, more external pins were available and assigned for addressing -- as a result a larger amount of external ROM or RAM can be accessed.

The technology behind the SuperFX chip would later become the ARC (Argonaut RISC Core) embedded microprocessor.

I thought the design was really creative, but...SHUT THAT BABY UP! Very annoying that I have to hear that Mario baby all the time.

[luishomeroremohsiul]

the most graphically beautiful game of the 16 bit era... debatable.. but still.. damn it looks gorgeous..

@JAndrad1991 Dude, just use an emulator and buy a snes usb controller and why would you want to play Doom on SNES, lol

[thepaesesai]

this game was beutifully done

[JAndrad1991]

My console can't play super fx 2 games anymore, like doom and yoshis island. It used to, but something got ruined. Can it be fixed? I want to play those games real bad!!! Someone help me! :(

Although I would reccomend replacing the battery with a socket so you can easily replace it without having to solder it, as this will just speed up decay of the board.

[tom2215]

only games that support saving progress/records have an internal battery. you can desolder and replace it quite easily once you open the cartridge, the waviness might be caused by a bad oscillator or a problem with the FX chip or it's ram, possibly the capacitors on board

[Nspinhead2]

I want this game,,, lol
