DaveC Posted September 4, 2017 Share Posted September 4, 2017 (edited) Hi guys, I have an issue with DEmul, I've tried with both Dreamcast and Naomi 2, they run great windowed but when I go fullscreen it just freezes. I can then ALT+ENT back to windowed mode but the emulation will stop and I have to restart the emulator. If I select 'Start in Fullscreen' it just goes black when I boot a game and not even the BIOS screen will load. I've messed around with different settings, edited the .ini files and disabled DPI scalings in the Windows demul.exe properties but no luck. Whatever I try, it will just freeze. Is there anything I can put into Launchbox command line to fix this or would I have more luck over at the dedicated DEmul forums? I've attached my DEmul settings here and have never had issues with any other emulators fullscreen (eg: Dolphin) Thanks so much.

DOS76 Posted September 4, 2017 Share Posted September 4, 2017 Try turning down your max layer to 16 Quote Link to comment Share on other sites More sharing options...
DaveC Posted September 4, 2017 Author Share Posted September 4, 2017 Thanks! But I've tried all layer settings and still I get the same thing. There seems to be others who have had trouble launching Demul in fullscreen, but most of these look like it switches back to a window after a few seconds, where as mine just freezes the emulation. I've tried different GFX plugins (DX11Old, DX10), and still nothing. Quote Link to comment Share on other sites More sharing options...
DOS76 Posted September 4, 2017 Share Posted September 4, 2017 Are you using the 08182016 build of Demul I've heard other people report they used the older version still due to issues. Also if your using Windows 10 try going into the Demul properties and check disable fullscreen optimization. Quote Link to comment Share on other sites More sharing options...
DaveC Posted September 5, 2017 Author Share Posted September 5, 2017 (edited) I'm using 180816 (the latest listed here: http://demul.emulation64.com/downloads/) but have tried v0.582, unfortunately with that I couldn't even get my ROMS to load, must be a different version ROM set maybe? So went back to the latest. I am using Win10 yeah, I will have a look for the 'disable fullscreen optimization' as soon as i get home from work. Do you recommend downloading 08182016? Really appreciate your help too, btw. Edited September 5, 2017 by DaveC Quote Link to comment Share on other sites More sharing options...
DOS76 Posted September 5, 2017 Share Posted September 5, 2017 no my bad they are the same build I just have the numbers mixed up. The full screen optimization checkbox will be under the .exes properties under the compatibility tab. Quote Link to comment Share on other sites More sharing options...
DaveC Posted September 5, 2017 Author Share Posted September 5, 2017 Thanks but nothing I've tried will work. Maybe it's my integrated graphics in my laptop. It's ok, I only wanted it for a couple of games. I really appreciate you taking the time to try and help! Quote Link to comment Share on other sites More sharing options...
DOS76 Posted September 8, 2017 Share Posted September 8, 2017 did you have to use the dism command to fix it? Quote Link to comment Share on other sites More sharing options...
DaveC Posted September 8, 2017 Author Share Posted September 8, 2017 (edited) Thanks for the reply. So running sfc /scannow would tell me if that is my problem or should I just go ahead and download that fix regardless? Is it just a case of copying the new .dll over the old one? The steps on your provided link warn of potential damage if not done correctly? Edited September 8, 2017 by DaveC Quote Link to comment Share on other sites More sharing options...
DOS76 Posted September 9, 2017 Share Posted September 9, 2017 I would run the scan it can help if there is Windows corruption in some cases it will fix the issues on its own. Quote Link to comment Share on other sites More sharing options...
DaveC Posted September 10, 2017 Author Share Posted September 10, 2017 Great, thanks for that! I will run the scan and see how I go! Quote Link to comment Share on other sites More sharing options...
