On a related note, to get perfect compatibility with games needing EMS on any computer built around the Vortex86 DX, use JEMMEX instead of HIMEM.SYS+EMM386, like this:

DEVICE=C:\DOS\JEMMEX.EXE X2MAX=32767 X=E400-EBFF

That makes the most hard-to-get EMS games to work, including Aladdin, Realms of Arkania II, Elder Scrolls: Arena, Lemmings 2, etc... All the hard ones work flawlessly!

Including, it seems, Wing Commander 3 (now it fails the way it did in Windows, at least).
@Mu0n have you tried JEMMEX instead of HIMEM?

- I have a BOM but not a component placement map or anything. I suppose I could work something up for that. I always hand assemble so I didn't really think of that.
- yep the front and back plates were designed specifically for this build so they should fit just fine.

I know it's asking you to work "for free", and I am embarrased to do so, but please, if you can, inlude a placement map too: I lack the abilities or equipment for hand assembling.
I was about to order the original WeeCee design pre-assembled at PCBWAY (that's why I was talking to Rasteri about it) but now that your fork is ready, I would prefer to have the USB-C connector.
But, without the placement map, I can't order it because I wouldn't be able to assemble it.

It's not work when you are having fun! I will see what I can do.
Also, I don't mind assembling one for someone myself if they wanted to pay for all the parts and some of my time for the assembly. Just throwing that out there.

instantly bombs with a conflict, I'm afraid:

I modified the JEMMEX parameter address range to the next 2k and it all worked out. Not sure what's recommended or forbidden in those choices, but I was able to go through the installer and launch the game!

thanks for the suggestion, that's a good tool from the freedos world.

What's your exact JEMMEX line, please? Just to be sure 😀

it's just yours, but +2048 (or +0x800), so:

DEVICE=C:\DOS\JEMMEX.EXE X2MAX=32767 X=EC00-F3FF
