Might be a byte order issue...

Don't know what that means... could it make a difference between that it works on PC and not on Mac ?

You can try using the Generic SVGA driver after it's been patched to make it VESA compliant. Download svgaptch.zip from here. It has had the fewest problems of the drivers I've tried, but 8-bit color only.

PowerPC or x86 processor?

Trying it right away...

PowerPC (OS X 10.5.5)

The SVGA patch made my Windows 3.11 in 256 colours but I actualy see no difference between the SVGA and the normal VGA, it looks just the same.
When I installed the S3 drivers it looked a lot more different.

But the problem actualy is, if you run a DOS game in Windows 3.11, and quit it, you're screwed, you'll get some red/purple stripes on your DOSBox screen. Somebody on the forum said it came due the standard VGA driver and that you needed to install another driver so it supported more colours. If I install the S3 drivers, the problem is solved (except the wrong cursor) but if I use the patched SVGA the problem isn't away, then I get other another colour of stripes after quitting a DOS game.

BTW, changing the Windows cursor doesn't work either.

if you run a DOS game in Windows 3.11

Don't do that.

Why not? 😕 it works with the S3 drivers[/quote]

Might be a byte order issue...

Can something like that be fixed?

Running DOS apps in Win 3.11 is not supported. In the development version the S3 screen mess-up is fixed but the console is really broken.

I don't know for sure if the pointer problem is fixed but you could try the development version nevertheless, that is if Mac builds are availible.

Downloaded a CVS (dated from July) I see there are indeed some changes with the screen mess up thing, but not the cursor. Couldn't find a list with changes.
Thanks anyway

Very likely. Casting a byte array to words will get you into shit.

From VGA_Draw_VGA_Line_HWMouse(), vga_draw.cpp:

1			for(m=0;m<4;m++) {
2				bitsA = *(Bit16u *)&vga.mem.linear[mouseaddr];
3				mouseaddr+=2;
4				bitsB = *(Bit16u *)&vga.mem.linear[mouseaddr];
5				mouseaddr+=2;
6				z = 7;
7				for(r=15;r>=0;--r) {
8					mappoint = (((bitsA >> z) & 0x1) << 1) | ((bitsB >> z) & 0x1);
9					if(mapat >= vga.s3.hgc.posx) {

JAL

So can I fix it ?

So who is going to fix it? xD

some byteswapping should be easy to test.

Me if you tell me how to 😀

Or maybe you could explain me how to test it ? 😉

Get a debugger, debug it, be happy.

Can you apply a patch to DOSBox CVS and compile it for your Mac?
