## BIOS
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

## Console button overlay
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.

## Controls
* **Console Overlay** - allows the user to view and select console buttons.
* **Controller Swap** - Controller Swap swaps the player 1 and player 2 controllers.
