+## Fairchild Channel F Core
+
+Authored by Asnivor
+Additional (invaluable) help from CasualPokePlayer
+
+This is (I believe) a cycle-accurate implementation of the Fairchild Channel F, a home video game console released in 1976. 
+The Channel F was the first programmable ROM cartridge-based console, and the first to use a microprocessor. 
+It was designed by Jerry Lawson, who was one of the few African-American engineers in the industry at the time.
+The Channel F was not a commercial success, but it was a pioneering system that laid the groundwork for the video game industry as we know it today.
+
+The Fairchild F8 processor is an unusual implementation, consisting of several modular components working together as a single unit.

+
+The Channel F is essentially a very simple system, with an F8 processor implementation, no traditional RAM (although certain carts have RAM on board and the processor has 64 * 1 byte scratchpad registers that can be used as storage).
+Sound is generated by a very simple tone generator circuit (allowing squarewaves at 3 set frequencies to be output) and video is generated by a circuit that reads directly from the onboard VRAM (that can only be written to).
+
+
+### BIOS ROMs
+
+BIOS files are not included with Bizhawk, but are required for the system to function.
+
+| Emulated System | Required Files | MD5 Hash | SHA-1 Hash |
+| --- | --- | --- | --- |
+| Channel F | sl131253.bin | AC9804D4C0E9D07E33472E3726ED15C3 | 81193965A374D77B99B4743D317824B53C3E3C78 |
+| Channel F | sl131254.bin | DA98F4BB3242AB80D76629021BB27585 | 8F70D1B74483BA3A37E86CF16C849D601A8C3D2C |
+| --- | --- | --- | --- |
+| Channel F II | sl90025.bin | 95D339631D867C8F1D15A5F2EC26069D | 759E2ED31FBDE4A2D8DAF8B9F3E0DFFEBC90DAE2 |
+| Channel F II | sl131254.bin | DA98F4BB3242AB80D76629021BB27585 | 8F70D1B74483BA3A37E86CF16C849D601A8C3D2C |
+
+The model of console (Channel F or Channel F II) along with region (NTSC/PAL) can be selected via the core SyncSettings menu.
+All games are compatible with both models and both regions (and all clones).
+
+
+### Titles
+
+There are limited titles available for the system, but there are some more recent homebrew games that stretch the system in some interesting ways.
+
+The latest supported ROM list can always be found here:
+https://github.com/TASEmulators/BizHawk/blob/master/Assets/gamedb/gamedb_channelf.txt
+
+The console comes with two built-in games, Hockey and Tennis.
+Due to the ROM-first nature of Bizhawk, the core has been set up to load the onboard games if any of the BIOS files above are supplied as a game ROM.
