Getting DosBox in fullscreen?

goodpi31

@tekn0 Does that make it fullscreen for you?

I'm also on a 1080p display- and even though I managed to increase the screensize of the dosbox (I think I used normal3x or normal2x), it's still not fullscreen as it would using a pc with dosbox installed.

@goodpi31 try setting

Aspect=true

It is the only way i can get it on my setup. Im using a tv that is 1024x768 however.

@edmaul69 Yep that did the trick. Thanks :)

@goodpi31 you're welcome

Interesting, setting that to false is what works for me in full screen. Testing sierra games and dune2.

@tekn0 yeah i set dispmanx as you said. I looked at your config and it is all the same as mine except for the aspect. I was testing on retro city rampage and a couple leisure suit larry's

@edmaul69 It is a little odd. I just updated everything in retropie including kernel updates as of 1/20/2017. I started with a fresh dosbox and the default conf file. Then enabled dispmanx in retropie-setup and coped over my conf file from the pastbin above.

Instant full screen at 1080p with what looks like proper integer scaled scanlines. Perfect. Setting aspect to false is really the key for me. Not sure how or why. I just have a standard 1080p led tv and standard hdmi cable.

Sorry for the Necrobump, but now I got DOSBOX to work, I would like to add a
CRT-like filter for it. Round corners (not just overlays), and the stuff. I'm editing my dosbox-SVN.conf, and added:

fullscreen=false
fulldouble=false
fullresolution=original
windowresolution=original
output=overlay
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper-SVN.map
usescancodes=false
pixelshader=CRT-geom-curved.fx

And later in the file:

[render]
frameskip=0
aspect=true
scaler=hardware2x

So... It's not working. No error output, just nothing at all. I dunno if it's the shader file (where do I even put it?), the fact it's not supported, or what.

Is there a way to make this work? :)

@lasagnadevil not sure about adding shaders. If you read through everything in the config it tells you what to change for scan2x or scan3x i think it is.

Indeed, but I found this:

It kinda allows for a CRT-fishbowl-shaped effect. :D

@lasagnadevil looking at it, that appears to be for dosbox daum, which can do more than the standard dosbox. If you get the curvature to work let me know.
