Hi
I am finishing (at last!!) my supergun, which uses a Neobitz encoder. So far, I've tested it with Atomiswave, CPS2, MVS and a PGM boards. However I have some issues, and I'd like to ask here if somebody can help me please:
1. The video output is nice if I use composite, but if I use component video, the picture looks like "too bright". This happens with all boards I have tried. Should I put resistors in the RGB video inputs? if so, why does the picture look nice in composite mode? I do not have a TV with S-Video, so that's untested so far.
2. The PGM board does nothing. If using composite, I turned it on, it makes some music, but nothing is displayed on the TV. If using component, I turn it on, a kind of splash screen is displayed, then the TV says "invalid resolution". Is there a trick to make the PGM work with the Neobitz encoder? I do not yet have a cart to test, only the board.
3. The MVS sounds strange. I know it's not JAMMA compliant, and I should put a switch to change the supergun between MVS mode and JAMMA mode. However, I read that if the SG is in MVS mode, and you connect a JAMMA board, it may get fried. Is there a circuit to avoid this? I usually forget to check basic stuff, and I'm sure if I let it like this, sooner or later I'll fry the Atomiswave or a CPS2 by plugging them whith the SG in MVS mode.
4. Atomiswave and CPS2 have fans that are so damn loud. Can they be disabled, or at least make them spin slower? will this damage the boards in the long run?
I believe that's all. Sorry for the wall of text. Any help is appreciated.
