I'm using an PS/2 version of the IPAC-4 with the update chips that allow it to be used with the new control panel designer software. I've programmed 3 different panel layouts (MAME, VPinball, and Virtua Fighter 2 - PC).
When I open a layout and upload it to the IPAC using the designer GUI, everything works fine. However, if I try to upload a layout via the command line, it doesn't work. The little status window says "downloaded successfully", but none of the inputs are remapped(although I feel like a couple of times some of them were, but I can't seem to reproduce that now).
I first saw this behavior when trying to program the IPAC through MameWah, but I can also reproduce it if I manually try to program it from the command line.
For what it's worth, I'm running the WinIPAC software on Windows XP (latest MS updates) / P600 / 512MB.
Has anyone else seen this before? Any suggestions on how to fix it?
Thanks.
