Wasn't there only one revision of the LuckyStar LS-486e which supported EDO? I forget which one it was now. SIS 496 'PR' Revision Northbridge supports EDO-RAM. Is SiS85C496 'NV' produced in 1997 capable of EDO? AFAIK 'NV' is not EDO compatible, only 'PR' is. The LS-486E that I have is also an 'NV'. …

That's interesting to know, I never perceived these different "attack modes" neither back in the days nor today ;-) IMHO, consistent attack damage would be useful. Neither did I... But since I heard of it, it is hard to forget about it and pretend the direction does not matter. So it really needed …

For a brief moment i misunderstood this ran on SVGA on pure DOS. Oh well. The title of this topic is not quite right... I worked on this Dune Dynasty port in the past weekend. Added an enhancement option to get rid of the attack directional effect. Wonder why the game was ever released with this …

I'm looking for a way to disable CPU cache, before the memory manager loads. A lot of folks use QEMM and DPMI. May be a worthwhile feature to add. I am sorry for the delay. I missed a reply notification. Attached CACHEOFF.zip with source code. This is for L1 cache only. It is very simple. Now this …

I applaud the changed by crvs, - He seems to have fixed the issue I had with more modern compilers, so with these issues fixed, fine with me.

Don't think there is any other thread about Dune Dynasty here on Vogons. It seems the SourceForge SVN source code version has significant additions compared to the last official release. The last official release being v1.5.7 of august 2013. It is work done in 2013 to 2015 by the same author; Mr. …

What may be good to know: Normally I look for texture filtering to make sure OpenGL mode is functional. Though since about a year OpenGL texture filtering is disabled in EDuke32, because it is incompatible with palette cycling or something.

Original Doom had only one graphics mode to support. MBF has VGA 320x200, Mode-X 320x200, VESA 320x200 and 640x400 with different methods of paging. MBF 2.04 has routines for transferring complete screens to video memory in these modes, and it requires different code in each case. MBF 2.04 does not …
