There are still some bugs remaining but the interface is usable and stable Following link is the driver needed, S3 864 v1.41B5 864141b5.zip http://www.winsite.com/bin/Info?4009 I've only tested 640x480 and 800x600 in 256 colors using SF or LF modes. You may have to skip the Windows splash screen by running, "win /b".

Plus it seems the mouse stopped working when I installed SB16 drivers. Standard mode is fine, other than that I too have a feeling mouse is mooving faster in X direction than Y. Somewhat annoying...but still, great job!

Also, mouse moving is about twice as fast in X axis direction than in Y. Last edited by Srecko on 2004-12-23 @ 11:58 am; edited 1 time in total

It has to do with the raster drawing code being ambiguous as to what line its on. The following lines of code are the offending parts: Qbix, Harekiet, what is the proper method for detecting what line the video card is on? Code: static Bit8u * VGA_Draw_VGA_Line_HWMouse(Bitu vidstart, Bitu panning, Bitu line) { if(vga.s3.hgc.curmode & 0x1) { Bitu lineat = vidstart / ((160 * vga.draw.height) / 640); //Bitu lineat = vidstart / 160; 160 works only for 640x480 (....) } (....) }

If you can provide a complete list of games that "suffer" from it I will/can/might fix it. _________________ Water flows down the stream How to ask questions the smart way

Some Illegal Opcode I believe in the latest Version of DOSBox from the CVS. I'll have to double check though but that's what I'm getting. When I use the VGA driver w/ Quicktime 2.11 everything runs okay. I'll try a newer version of quicktime but I know it works with the other VGA 3.0 or VGA drivers. These are though what I saw for 90% of the log that I dumped before it dumped out of Windows 3.1 into DOS. 43727096: CPU:Illegal Unhandled Interrupt Called 6 43727098: CPU:Illegal/Unhandled opcode 63 It just showed that over and over and over. _________________ Ieremiou ---------- Helping Debug DOSBox.

But with "dynamic" core it shows this message at startup and the audio doesn't work anymore. I'm using latest cvs + sdl1.2.8. + vc.net 2003 win.png (21.24kB) - Downloaded 1332 Time(s)

priestlyboy I am MechMan "Please Stand Down" Joined: 2003-11-05 Posts: 510 Location: New York	Thanks for the exception fixes wd. Quicktime runs properly now in enhanced mode. I can now play an old game called Castle Explorer in 256 colors. Yes an educational game but a fun one. /Ieremiou _________________ Ieremiou ---------- Helping Debug DOSBox.

I encountered problem in 640x480 with 256 colors, but it seems 800x600 with 256 colors(LF) is fine.
