- I-PAC2 v1.55c — WinIPAC Crashes on Config Push, Board Reboots
(1/1)
mark0804:
Hi all — hoping someone can help me crack this persistent issue with my I-PAC2 board running Multi-Mode firmware v1.55c.
I’m trying to push a custom .ipc config using WinIPAC (installer version V2.1.41, executable shows 1.0.41.2). The board is confirmed to be in Keyboard Mode with Multi-Mode firmware active. All signal pins are disconnected except GND to avoid rogue mode triggers.
Here’s the problem:

* I load my .ipc config (all pins mapped to Gamepad buttons)
* Click “Force Board Reconfiguration”
* WinIPAC immediately shuts down or crashes
* Board reboots into DInput or XInput Mode, but WinIPAC then reports “Keyboard Only Firmware”
* I can’t push config again unless I reflash firmware and start overI’ve tried:

* Reflashing firmware cleanly
* Using minimal .ipc config (just Dpad + A/B + Start + Hotkey)
* Disconnecting all inputs during push
* Switching USB ports
* Running WinIPAC as AdminStill no luck — config push crashes every time. I’m on Windows 11, and Batocera sees the board as “Microsoft X-Box 360 pad” when in XInput Mode, so the mode switch works — just not the config.
Any ideas? Is there a more stable version of WinIPAC or a workaround to push config without crashing? Appreciate any help — this is the last hurdle in my arcade build.
Thanks!
