Having problems with creating a DOS extended graphic file

[Minim]

I'm at the moment having problems with creating an extended graphic file while using the program Lemmix. I've figured out that you need at most 8 colors (Along with black, the background color, but the biggest problem is, I don't know which colors pass the planar bitmap scale. I even tried using a 16-color palette to design a level, and even that is unacceptable (It won't even accept 255, 255, 255, which is actually white). Are there any suggestions as to what I can do to get through this problem which seems to complicate every time?

Haven't tried this myself, but I have a random idea. L1 doesn't use 8 bits for one color component, but only 6. Try making white with 0x3F (decimal 63) in each entry.

Hmm, I actually believe Lemmix should be smart enough to convert. I'll get breakfast first, and afterwards try myself or peek at the source code.

Now after breakfast: The editor is closed-source for some reason. So it's random trial-and-error time.

The day after: Eric told me he has lost the Lemmix editor source due to a disk crash. :-/

I haven't used the Lemmix built-in function for that, however if you don't get it to work, you can use ccexplore's myvgaspec.
I attached it in case you don't have it (I hope ccexplore doesn't mind).

I have the Lemmix 0.0.10.0 source.  (You'll probably have to rename the download since the IPv6 gateway doesn't seem to forward the filename properly... or just use this link if you have IPv6.)
