vga scan doubler


Recommended Posts

Not at all sure anyone is going to like this but the games look too good on lcd displays...

the old analog 15kHz monitors have very visible scanlines between consecutive rows.

The vga scan doubler used would be easy enough to modify to output 0 for every doubled (vga) scanline

like mame's original -scanlines option but that really does not look at all better on a lcd screen.

I've been experimenting with galaxians today to see if there is a way to get a worse picture with little effort...

Attached is what i came up with (my real PCB hasn't been booted up in almost 10 years and i really cannot remember if this even close to what it looked like on the wg it was hooked up in :)

no way to take a screenshot so you will just have to synth and run yourself :)
