How Do I Use The Practice Hack?

You will need a flash cartridge to run it on hardware with an SD card formatted to FAT32 or simply an emulator. Currently, the only devices that can run the practice hack are the Super UFO Pro 8 and the SD2SNES (now known as the FXPAK). This is because no other flash cartridges support the Super FX 2 enhancement chip.

  • If you're using a Super UFO pro 8 you will need to download the version of the practice hack that matches the version of your Yoshi's Island cartridge, otherwise it won't work. Check out the version differences page to determine what version you have.
  • If you're using an SD2SNES, just download the Japanese version of the game (it's slightly faster than English).
  • Copy the practice hack ROM from your computer and place it onto your SD card. Any SD card should work - the practice hack is only 2 MB.
  • Insert your SD card into your flash cartridge.
  • Play the game.

SD2SNES/FXPAK PRO

The SD2SNES, now known as the FXPAK PRO [1] is a flash cartridge that is modeled after Super Famicom and SNES carts and is not region locked. It is basically a powerful emulator that can run 99% of SNES games (including romhacks) on an actual SNES/SFC via a micro SD card. It also supports a majority of enhancement chips [2], namely the Super FX 2 chip that Yoshi's Island uses. The firmware is free to download but the hardware is rather pricey (around $200 new). The trade-off is that it's super reliable and fast, two things that the UFO lacks.

Super UFO Pro 8?

Similar to the FXPAK PRO, the Super UFO Pro 8 is another flash cartridge that can run ROMs on console via SD card. It is shaped very similarly to Super Famicom cartridges with a removable cap on the top that allows you to insert an SNES/SFC cartridge. Unfortunately, when running Yoshi's Island, the UFO is often unreliable and can crash at random (probably due to needing the actual cartridge plugged in on top), making it annoying to use for practice. In all honesty, it's probably best to avoid this flash cart and get the FXPAK PRO instead. At one time this was the only way to run the practice hack on console (and it was cheaper) but that's not the case anymore.
