FreeChaF is a libretro emulation core for the Fairchild ChannelF / Video Entertainment System designed to be compatible with joypads from the SNES era forward.
FreeChaF was created by David Richardson.
The FreeChaF core is licensed under GPLv3.
FreeChaF requires two BIOS files to be placed in the libretro 'system' folder:
| Filename | Description | MD5 |
|---|---|---|
| sl31253.bin | ChannelF BIOS (PSU 1) | ac9804d4c0e9d07e33472e3726ed15c3 |
| sl31254.bin | ChannelF BIOS (PSU 2) | da98f4bb3242ab80d76629021bb27585 |
If the ChannelF II BIOS is included, it will be used instead of sl31253. All games are compatible with both.
| Filename | Description | MD5 |
|---|---|---|
| sl90025.bin | ChannelF II BIOS (PSU 1) | 95d339631d867c8f1d15a5f2ec26069d |
- BIOS filenames are case-sensitive
Access to the console buttons is provided via an overlay. Pressing 'start' on either controller will display the console buttons. You can select a button by moving left and right and press the button with any of the face buttons (A, B, X, Y). Pressing 'start' a second time will hide the overlay.
- Console Overlay - allows the user to view and select console buttons.
- Controller Swap - Controller Swap swaps the player 1 and player 2 controllers.
