Yes, the issue was figured out... the flicker is because the character set data resides in the ROM, and as ANTIC is drawing the screen it sometimes is getting garbage data because the ROM is off. Basically, the driver needs to copy the character set to RAM and avoid this bit for storage. I want to rewrite the driver anyway, since it doesn't really need to jump through the stack since main memory should always be there, which should make the driver simpler and faster. At the least it shows MULTDEMO run the way it should... loading different drivers and picking one that works. Speaking of MULTDEMO, does it only check a certain number of files in a directory (doesn't seem to, looking at the code, so maybe it's readdir that does this?) I noticed putting the driver further down the directory list causes it to not find the driver. > From: owner-cc65@musoftware.de [mailto:owner-cc65@musoftware.de] On Behalf > Of Ullrich von Bassewitz > > I've seen that there is a discussion going on about the flicker.
