Got a couple NAOMI driving games up and running on my main pc (Vista) and wrote an autohotkey script to make them go fullscreen and play nice with my front-end.
Once everything was sorted and working right, I copied it to my driving cab, which runs XP.
On it, I get the following error when a game is launched:
I click OK, and the game plays perfectly fine.
From what I gathered googling the error, HRESULT = 80070057 is an invalid argument and
IDirectInputDevice8 CreateEffect FAILED has something to do with force feedback (which I didn't think Demul supported).
I reset all the gamepad mappings to NONE - same result.
I deleted the padDemul cfg file - same result.
I made sure all the P1 controls were mapped to something for Dreamcast, Naomi & Atomiswave - same result.
I turned off force feedback in windows control panel>gamepads - same result.
The only thing that gets rid of the error is changing to xinput, but then of course my controls don't work.
I was using a logitech gamepad (no rumble) on my main pc and I'm using a logitech momo wheel on my driving cab.
Anyone have any insight?
