Hi.. :) I have found out why Orion Burger (and a few other games) works fine with UniVBE but the display is truncated after the first 65536 pixels with the built-in VESA driver. The VBE2.0 specifications for the function "Display Window Control" says to set DX to the "Window number in video memory …

Could anyone test the MODIFIED UNIVESA (For 5.1 and 5.3a versions) made by Rob Muller. (I'm at work). It's just UNIVESA's created driver but modified to use bios built-in VESA on your card. Here. Doesn't work here. Output in the DOSBOX Debug window: Illegal write to f0a14ba Illegal write to f0a14bb …

I don't have the games So I don't know how they acces the mouse driver. I don't think this is a mouse driver problem. The game only acts up when you click below the character but you can access the buttons - which are at the bottom of the screen - without any problems. So the game exactly knows …

No, I didn't test that. I was a little pressed for time on New Year's Eve and only checked the beginning of the space ship scene. Sorry.. But I can confirm the problems Jiri described. Also, if you try to enter the house of your grandma, your character will walk backwards through the door and you …

Orion Burger works great with the new CVS version if UniVBE 5.3A is used (otherwise, only the first 65536 pixels are shown) The DOS4GW.EXE is upgraded from version 1.95 to 1.97. This will speed up things significantly. Great work.. 😁

I had the same problem with the graphics, just run UniVBE 5.3a from SciTech before Orion Burger and it will work. It seems that Orion Burger is doing something quick&dirty not supported by the built-in VESA support. This may also help with Master Lu but I don't have that game so I cannot test it.

Hi.. :) I was able to run Orion Burger using the latest CVS version but only after changing the code so the mouse driver always sets BX=0x0000 (mouse enabled) in reply to AX=0x0026 (Get Maximum virtual coordinates) instead of 0x0000 if the mouse is visible and 0xffff if not. Otherwise, the game …
