Hello , I have a strange problem, with DOSBOX 0.70 when playing with BattleChess 4000 the screen shows "os_size changed" message onscreen each 2-3 seconds, and filling the game screen. The game displays 640x480 256 colour SVGA and in setup I selected Trident SVGA, there was no S3. The game works …

Here I am again, I have recently installed catalyst 7.4 and after some testing the results are: The system is somewhat faster in 3d games (windows, direct3d) but in Dosbox the situation is the same. No way to get 640x400 70Hz without programs like powerstrip. Maybe there is a catalyst that will work …

Hello! I have been investigating this, and it seems that you were right after all: With no Dosbox.conf file, dosbox will display 640x400 but with incorrect refresh rate, so the monitor will show no resolution and the screen is off-centered. Trying to fix the refresh rate issue with refreshfix or …

Well, I guess I should try the new catalyst and see what happens... I'll post here with my findings when I change drivers. Thanks for helping! Ertoil.

This …

Well... I have tried several combinations of fullscreen=true fulldouble=false fullresolution=original windowresolution=original with output= surface, overlay and ddraw also with aspect=true and scaler=normal2x The display is set always as 640x480 60Hz (dosbox prompt, and ingame),prompt with black …

Hello all! Thanks for replying, first of all, and no, I dont have LCD monitor. I have Philips 201B 21'' monitor CRT, I dont like LCD because they are fixed resolution, and I play a lot MSDOS, windows , MAME, etc, so the flexibility of CRT is invaluable to me. I have two systems, fx-60 with ati …

Hello! I was wondering if there is any way to select the real resolution of MSDOS mode, I mean, when you are in real DOS, in win98 DOS mode or winxp dos the resolution is 640x400 70Hz (sometimes reported by some monitors as 720x400 70Hz). I have tried all sorts of combinations of fullscreen , …
