# Credits
I mostly ported the emulators from existing projects, all the credit goes to the authors of
-colem, o2em , x2600, moarnes, mc-4u, sz81, atari800, Vice, Nofrendo, jun52, dcastaway, vectrexemu (sorry if I don't mention their name), Charles Macdonald (TGemu), Bernd Schmidt (UAE) and Mike Chambers for his 8086 Arduino project!

Doom is based on the ST32 port of chocolate doom so thanks for initial porting effort.
Thanks a lot also to Frank Boesing for his ILI DMA library from which I started from and his great Teensy64 project https://github.com/FrankBoesing/Teensy64
