I have just today got windows running on arcade monitor with a g400 running the interlace util. It runs windows fine, a little flickery. but that was expected.
After a little tinkering I found that if I changed the mame32 settings as follows:
resolution: 640 x 480
depth: 16bit
to match my desktop settings and the rest of mame32 set to defaults, it displayed every game I tried full screen hardware stretrched to fit the screen (excect vertical games which had black borders to the left and right, as I had hoped).
I have played around with dosmame/arcadeos/advancemame with mixed results. Yes, the majority of games worked fine but there was so much tweaking involved, and some games I could never get to work right.
What I'm looking for now it a decent frontend that will drive mame32 using the settings I need. I really don't want it to look like a windows program. Any suggestions?
