I've bought some super-cheap STM8S 8-bit microcontroller based boards and I was wondering what kind of cool project I could put them to use. I've mixed it with an USB Host Mini 2.0 module a CPLD and some discrete components and then the USB2Classic adapter was born!
This adapter allows you to use USB controllers with old consoles, such as:
- Sega Genesis / Mega Drive (can emulate either a 3 button or 6 button pad)
- Sega Master System, Atari 2600 and others
- Panasonic 3DO
- NES
- Super NES
- Sega Saturn
- Neo Geo
- TG16/PC-Engine (through adapter board connected to the Neo Geo output)
Currently compatible USB controllers are:
- Playstation 4 USB controller
- XBOX 360 USB controller (and compatible XInput devices)
- XBOX 360 USB Wireless Receiver
- 8BitDo Wireless USB Adapter (in XInput mode)
- Some PS3/PS4/XBOX360 USB arcade stick controllers
The CPLD originally used by this adapter is an EPM7064SLC44-10N which is 5V based. Verilog sources are inside the multi-out directory along with Quartus II project files.
The USB Host Mini board MUST be modified for 5V as shown in the doc/usbhost_mini_5v_mod.png diagram.
Firmware was compiled using SDCC version 3.8.0
Thanks to Bruno Duarte Gouveia (brNX) for all the help with Verilog!
Enjoy!
