Releases: eyvind/sega-adapter
Enhanced SNACK support
SNACK enhanced mode support
Add support for the enhanced mode of the SNACK adapter, which allows SNES controllers to be used on an Atari. The enhanced SNACK mode allows more than three buttons to be read by the Atari and is supported by a few games.
Six-button autofire support
Six-button controllers have extra buttons X, Y, Z, and (sometimes) Mode. This release detects the extra buttons and uses X, Y, and Z as autofire versions of the A, B, and C buttons.
As with the previous releases, the .hex file is for PIC programmers while the .atr is for an Atari with a Joy2PIC.
Amiga support
This release tweaks the Atari mode to also support the Amiga.
C64 support
Add support for C64, C128, and VIC-20, which expect the second and third buttons to be active high rather than active low. To switch to C64 mode, pull the /C64 pin (pin 4) low.
Note that the pinout has changed since v0.1.
Initial release
The program is fully functional, but barely tested.
Provided binaries are a .hex file for programming the microcontroller from a PC and an .atr file to use with the Atari JOY2PIC programmer (https://ataribits.weebly.com/joy2pic.html).
