This is code for a Teensy-based SNES TAS playback device. The code has the TAS hardcoded into it,
so short Python programs have been included for working with the TAS data, which can be found in
the tas-work folder.
It comes with a modified version of the Masterjun SMW "ends input early" April Fools' Day TAS, which instead of forcing the SNES to TAS the game itself, installs the jailbreak onto save file C.
The TAS installer will erase the save files itself before proceeding. This requires you to hold down the Reset button on the SNES at a certain time.
In the project folder:
make teensy will run the Makefile in the teensy directory, which will build the Teensy program
that plays back the TAS.
make upload will upload the Teensy program onto a Teensy 2.0.
make clean will clean up all the temporary files.
Once you have a Teensy loaded with the program and properly hooked up to the SNES, you can install the jailbreak by following these steps:
- Power on your SNES with Super Mario World in the cart slot.
- Wait for save files A and C to get erased. The light on the Teensy will change its pattern to indicate that the files have been erased.
- Hold down the Reset button on your SNES until the light on the Teensy goes solid. This will happen after the light blinks five times.
- Release the Reset button.
- Wait for the TAS to play back.
At the end of the TAS, your game may appear to be frozen. This is intended. Observe the light on the Teensy. If it is blinking once per second, it is safe to power down your SNES. When you power it back on, you should find that the jailbreak has been installed. Enjoy! :)
