Retro Adapter Mod v1.3
Retro Adapter Mod is a firmware mod for Paul Qureshi's Mojo Retro Adapter based on original Atmega168 code by Paul Qureshi and Bruno Freitas.
With the adapter one can connect old controllers to PC. This firmware mod adds support for using your old controllers on the Xbox classic and Android host systems, as well as support for the NegCon controller.
The bin archive just includes the .hex files needed to update the firmware.
The src archive includes all sources, binaries, and the original code this mod is based on.
See included readme.txt for more info.

Changes since v1.2:
- (Android/Windows) Speed optimization! Used joystick frequency tester to optimize update rate. All single player mode controller rates are now 100 Hz (NegCon 50 Hz). For comparison, a Mayflash Dualjoybox Pro gave 66 Hz (44 Hz for NegCon). I suspect two player mode is also 50 Hz, but I cannot test it because there is no analog axis.
- (Android/Windows) reverted back to USB poll interval 10 ms, since this is a low speed device. Lower numbers do not cause any difference.
- (Android/Windows) reverted back to only reporting the additional analog axes "Brake," "Accel," and "Throttle" in NegCon mode, since they slow the rate down (see above entry)

For NegCon in normal mode (Windows/Android), the analog buttons are mapped as follows:
| Host (Win/And) | NegCon |
|---|---|
| Steering | x |
| Button I | "Throttle" axis |
| Button II | "Accelerator" axis (Android analog right shoulder) |
| Button L | "Brake axis" (Android analog left shoulder) |
- Arcade mode:
This version is suited for use in an arcade cabinet. It works on PCs just like the original RetroAdapter, but I replaced Neogeo stick support on the DB15 with an arcade mode that has just 8 firebuttons on the DB15, to give you a total of 10 buttons and 4 directions when you hook up your Arcade controls to pins on both DB9 and DB15.
The pinout for the arcade mode (no button 3 and no button 6 to maintain Android compatibility):
DB15
pin 3 - button 7 (Android L1)
pin 4 - button 5 (Android Y)
pin 5 - button 10 (Android R2)
pin 6 - button 11 (Android Select)
pin 7 - button 12 (Android Start)
pin 11 - button 8 (Android R1)
pin 12 - button 4 (Android X)
pin 13 - button 9 (Android L2)
pin 1 - GROUND
