Minimal requirements:
- Teensy3.6/Teensy4.0 or ESP32 Node32S/Wrover SDK chip
- ILI9341 (Teensy/ESP32) or ST7789 (Teensy only) SPI display
- SD card (Teensy uses built-in uSD, ESP32 uses external one connected over SPI, e.g. ILI9341 integrated one)
- Analog joypad (Arduino or PSP like)
- 3 buttons (FIRE, USER1 and USER2)
Optional requirements:
- I2C custom keyboard (for computers emulators)
- Sound (DAC for ESP and Teensy3.6, MQS for Teensy4.0)
- VGA output (Teensy 3.6 only)
- 2 extra buttons (USER3 and USER4) mostly for NES emu
Wiring
- see pinout.txt file in the respective project (ESP32 or Teensy)
- Some KICAD image also available for ESP32
I2C keyboard (for computer emus)
- see i2ckeyboard sub-directory
- the I2C keyboard is using a separate atmega328p MCU handling the keys matrix
- with 10x4 or 10x5 keys
Installation
- Format the SD card as FAT32
- extract the content of SD.zip in the root directory
- there must be a sub-directorie for each emulator
- "2600" => for atarivcs, put your Atari 2600 roms here (.bin), with sub-dirs or not
- "5200" => for atari5200, put your Atari 5200 roms here (.bin)
- "800" => for atari800, put your Atari 800 cartridges here (.rom)
- 'c64" => for c64, put your C64 programs here (.prg), with sub-dirs or not
- "o2em" => for odyssey/videopac, put your Videopac/Odysssey roms here (.bin)
- "coleco" => for colem, put your Colecovision roms here (.rom, including coleco.rom)
- "nes" => for nes/nofrendo, put your .nes files here (e.g. galaga,xevious,mario1...)
- "spec" => for spectrum, put your ".z80" or ".sna" files here into sub-dirs or not ( max 48K )
- "z81" => for zx81, put your ".p", ".81"(, ".56") ".80" or ".o" files here ( max 56K )
- "st" => for AtariST, put your floppis ".st" files here
- "pc" => for 8086, put your HDD image ".img"
- "vectrex" => for Vectrex, put your ".gam" files here
- "pce" => for PC Engine, put your ".pce" files here
- "gameboy" => for Gameboy and GBColor, put your ".gb"/"gbc" files here
- "sms" => for Sega Master System/Game Gear, put your ".sms"/"gg" files here
- "gen" => for Sega Genesis/Megadrive, put your ".smd"/"bin" files here
- "msx" => for MSX roms, put your ".rom"/".msx2" files here. MSX system roms in msx/roms
- "amiga" => for Amiga floppies, put your ".adf" and ".hdf" files here.
-- insert the card into the SD slot
Compilation/flashing (Teensy)
- open the respective ino file with Arduino SDK
- select DISPLAY MODULE in tft_t_dma_config.h (ST7789 or ILI9341)!!!!
- double check iopins.h for pins configuration!!!!
- compile and install from there.
Compilation/flashing (ESP32)
- go to espboot directory first:
- make, make flash => this will install custom partition table, bootloader and app selector
- go to any other directory (one by one!):
- Adapt ./flashapp.sh according your OS (I use OSX)
- make, ./flashapp.sh

Running
- ESP32 only: Select the emulator from the app selector screen and press FIRE (wait a bit that the SD get mounted)
- For the launched emulator you should see the roms of the SD card being listed
- you can select the rom with up/down
- you can start the game by pressing the FIRE key
- while the game is running, you might have to press USER1 or USER2 keys to start the game
- some emulators requires the I2Ckeyboard
- You can then play the game with the analog joystick and the FIRE/USER1 keys
- press the USER1+USER2 to reboot the emulator and load another ROM
- USER2 can be used to swap joystick 1/2 in some emulators
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! 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
