- When I hold down the player 1 button 1 and button 2 and move the joystick it rotates my screen, which I'm guessing it's picking up the windows 10 option for screen rotation. Anyway to stop this behavior?
Disable windows hotkeys. Sometimes the option to disable rotation is in the video card software.
Personally, I prefer to just use other inputs on the Key-Wiz instead of the first four default MAME keys.
It saves a lot of hassles with other emulators. I usually substitute VBNM. If you still want to get use out of the oddball keys (TAB, ALT, etc), use them for things like coin input.
I've used the uploader software before, but find it a more bulletproof solution to just use different inputs.
- It shouldn't be an issue to power 10 or so 12v LED buttons offa the 5v connection right? Specifically these buttons http://groovygamegear.com/webstore/index.php?main_page=product_info&products_id=338
