I cannot get passed the incompatible vesa driver error when trying to run the original GTA in 24-bit mode on real hardware with an ATI Rage II+DVD card with Windows 95 or DOS mode. I am so unfamiliar with this vesa stuff and Im not sure what to do here. Any help would be greatly appreciated!

I cant remember so good. Its about 15 years ago.
But I think you need the correct version of the game and then you can use F11 to select what you want.

gta24.exe -nounivbe
or
k.exe -nounivbe

I don't remember exactly

this key works with some graphics cards, also you may need dos32a extender

Tried k.exe -nounivbe and gta24.exe -nounivbe. Unfortunately still getting this error.

Weird, cause in this case my laptop wrote:

No supported SuperVGA chip detected!

and works fine with -nounivbe key

try different GTA version?

Just for the history, GTA says
this when any mode announced
via 0x4f00 VBE fn, lacks the bit 0
in mode attrinutes (i.e. mode marked
as unsupported).
This is the usual situation on notebooks
that some of the modes are not
marked as supported, but GTA
treats this as fatal error.

With this patch to gta24.exe
it should skip the "unsupported"
modes:
```
001AA039: E8 E9
001AA03A: A4 3F
001AA03B: FC 01
001AA03C: FF 00
001AA03D: FF 00
```
