We have a new release which implements mode switching between dual Xinput controllers, dual DirectInput controllers along with the conventional keyboard/mouse/volume/power mode.
In this version, the device appears as a completely different USB device for each of the modes, which avoids any multi-device issues with Retropie.
The selected device mode is switched using a 10-second hotkey press and hold and is maintained after power off/on.
Switching can also be done automatically from WinIPAC including command-line.
There is a PDF information sheet available, and the firmware download for I-PAC 2 on
www.ultimarc.com/download.htmlOther boards will be rolled out, I already have the Mini-PAC version available for testing on request.
Any comments/feedback welcome!
