no chance to get it to work on that machine.
4MB of VRAM?
That means 640x480 is the total maximum screen resolution.
And even that already takes 1.2 MB of VRAM just for Backbuffer
And no that are 2D Cards, they didn't have shared RAM normally, as thats a card of the PCI generation. PCI was to slow for shared RAM, that feature was introduced with AGP.
The fact that DXDiag does not show that clearly makes this a fact as well.
Without implementing a pure 2D driver on base of DirectDraw (similar to BlitzPlus / Blitz3D 2D commands), which removes Alpha, rotation and scale in realtime, there is not the least chance to get that working.
DirectDraw works because its mainly using CPU and RAM, not GPU and VRAM
Alternative: trying to make a 2D renderer using something like Irrlichts apfelbaum software renderer, ie a high performance 3d software renderer.
Don't know, does Mesa3D exist? then you could use that one and fallback to OpenGL on such CPU based systems.
