Slightly edited version of our homepage news:
During the last two weeks there has been some major development progress on the Videl emulation again. We have got both Mono and 8-bit (256 colors) modes working in all VGA resolutions: 640x480, 320x480, 640x240 and 320x240. So now we have full support for 1,4,8 and 16 bit pixels on VGA.
We have fixed minor but hard-to-find bugs that sometimes caused "skewed" bitplanes.
We have run some demos (mostly DHS demos) that use 256 colors to see that our Videl cloning works. We have only run VGA 60Hz, since our LCD monitors can only handle this. In one demo we selected 100Hz VGA, and the monitor reported that it couldn't display "100Hz, 31.4kHz". This is good news for us though, since it proves that our Videl register translation code translates 100Hz correctly! :) We need to try it on an analog VGA to see it for real.
RGB resolutions is still untested.
2-bit color mode seems to become a larger issue, since the Videl supports this only in ST-mode, and we have no working translation code for this yet. The question is: Should we really put a lot of time into this now, when we have other more basic/urgent features to do before production, like JTAG updating and RGB support? After all, how often do you use 2-bit mode?... :P
Today we also tried running Henrik's dogfight game Aces High, which uses a rather unorthodox VGA-resolution of 384x250 in 60Hz using the 32MHz video clock (normally used by RGB modes). This works perfectly. :D

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
