THANK YOU !!! I followed your advice and took the previous DAUM version now, it works perfectly with the shaders via DBGL. but what is strange: you wrote with the latest DAUM version you are not able to get the shaders to work even with DOSBox Daum alone. The shaders with latest DOSBox alone are working perfectly with my computer. Either i setup my wished shader directly in the dosbox.conf or switching through live during play on the fly under "Video" / "Direct3D Pixelshader" - no problems at all.
some more questions, now referring to the sound settings, again i take Wing Commander as example:
1.) I want to enjoy Roland Sound (MT-32). If I use DOSBox Daum alone I only put the two necessary MT32-Roms into the DOSBox Daum root, change the mididevice to mt32 in the dosbox.conf
and choose in wc installer Roland sound - works!
Now I want to use Roland Sound also via DBGL. I copied the two MT32-roms into the "dosroot"-folder (and this time not also into DOSBox Daum folder). After that i launch DBGL, go to my WC-profile and choose "run settings". I choose "Roland Sound". If i now start the game i still only get Soundblaster sound. I think I have to click something more inside of DBGL to get Roland Sound? Kolano wrote above i should not change the dosbox.conf manually - only choose settings inside of DBGL because DBGL overrides the dosbox.conf inside of DOSBox Daum. So how to correct activate Roland in DBGL?
2.) In the Wing Commander settings I only can choose "Roland" - in many other games there is also the option to choose "Roland + Blaster", if the game has beside MIDI Music speech or digitized effects. How to setup DBGL in this case to get the best of both worlds?
3.) In most cases the two MT32-roms (beside soundfonts of course) are a good choice. If I take another game, "Might & Magic 3 - Isles of Terra" for example, it has a few (strange sound) problems with the MT32-roms, the better choice here is to use the two CM32L-Roms. If I copy these two roms also into the DOSROOT-folder and choose Roland Sound in the M&M-settings - how should DBGL know not to take the MT32-roms but the CM32L-roms in this case? Is there a way to choose the specific needed roms for each game?
4.) Back to the Display Options - i want to have 1280x800 (four times 320x200) windowed for many of my games, but the DBGL-Windows-Resolution-DropDown-Menu (what a word... 😀) only offers 1280x768 - is there a way to set my desired custom resolution inside of DBGL or do i have to change this in this case manually somewhere?
Once again thank you very much in advance for all your help. i learn a lot of things these days 😀
