Title says it all. This should be possible, right? Then you could choose 16 colors from all of the available 64 EGA colors instead of being limited to the 16 CGA colors, and still have a low enough resolution to push pixels quickly for a game.

This would require a real EGA monitor, though, something which seems to be very rare these days.

World's foremost 486 enjoyer.

I don’t think EGA can be reprogrammed in the same way as VGA in terms of custom resolutions

The maximum scanline variant of creating double scan (opposed to the dedicated double scan bit used in most VGA double-scanned modes) should work fine on EGA, too.

I seem to remember that one version of Paperboy did this in EGA mode. Or maybe it was 320x350, which should also be interesting (basically mode 10h at half the dot clock).

Or a multisync one. It'll work just fine on VGA as well, but there of course you'd already have an even larger palette built in.
