there are improvements to the joystick though.
Emulating a DOS joystick with a modern console joystick is one of them, as well as deadzone emulation for both DOS joysticks and modern console joysticks

I tried the vJoy, PPjoy and Virtual Controller. BUT I had the same issue with them. If I push/pull the mouse to 1 direction the (for example) plane starts moving but does not continue the movie... so i have to push/pull again. These emulators do not keep the started moving speed like a joystick does (like in the Xwing and TIE Fighter DOS games when the player wants to use mouse instead of joystick).
So, u push the joy a little and the plane starts to move slowly and you push the joy more harder it move faster in these emulators it does not happen.

No, I haven't but I'll try it! Thanks! I hope I find a joy emu. whereby I can use a mouse as a joystick!

Integer Scaling (or Pixel Perfect i think) is very needed (also when i use scaler=scan2x or other, so also with scanlines enabled)

If you're looking for pixel perfect scaling, you shuld give DOSBox ECE (see my signature) a try! :wink:

I don't understand the 'is very needed' part, please explain.

check this http://tanalin.com/en/articles/lossless-scaling/


for now i have to configure manually all my gog games... (1600x1000 for 320x200 games, 1280x960 for 640x480 games; many issues with 800x600 games that need that feature...)

this with gpu scaling with "no scaling" selected into nvidia driver (display scaling i very bad...)

My pixel-perfect patch (available in DOXBox ECE) just applies integer scaling to use most of the monitor area while approximating the target PAR (pixel aspect ratio). What effect do you mean by scanlines?

The article on lossless scaling you referenced does not mention scanlines either.

Scanlines are good only when an integer resolution is applied, but is required to disable scaling in gpu driver, so i have to use "no scaling" and gpu scaling is necessary... (tested a resolution of 1600x1000 with some 320x200 games and 1280x960 with some 640x480 games, output=opengl, scaler=scan3x first and scaler=tv3x next for 320x200 games, scaler=scan2x and scaler=tv2x for 640x480 games; with a non-integer resolution there are bad scanlines and many distorsions, so is the same problem... tested also output=openglnb but it cause some distorsions also with all these resolutions, so is not recommended... and i think that output=surfacenp is the same, but i haven't tested it for now)

So if i want to use scanlines with games i have to use output=opengl because output=surfacepp is... "capped" to scaler=none...

i've tested the same games also with scaler=normal5x but is not the same... so output=opengl wih 1600x1000 resolution on 320x200 games is not the same as native resolution and output=surfacepp... (with native resolution and surfacepp all images and pixels are perfect with all games, but lack scanlines...)


Many old games are good only with scanlines... i suggest to add support of scanlines also for Pixel-Perfect Patch, without add a 2x or 3x scaling (that is not need with native resolution i think, and Pixel-Perfect patch use only scaler=none because a scaling 2x or 3x is not needed)

some scanlines are these https://www.google.it/search?safe=activ ... rgD_vuEvV4

note: that Pixel-Perfect patch will not be needed (i think) if nVidia, Amd and Intel will add integer scaling in a next driver (but we don't know if can happen... so don't remove it)

FulValBot, do you need pixel-perfect scaling applied on top of a scanline filter? It seems possible.
note: that Pixel-Perfect patch will not be needed (i think) if nVidia, Amd and Intel will add integer scaling in a next driver (but we don't know if can happen... so don't remove it)
It will still be needed, but the implementation will be simpler. It is not a good idea, however, to rely on a specific hardware manufacturer.

FulValBot, Here is Pinball Dreams 2 running in my experimental implementation of Pixel-Perfect mode with OpenGL:
Code: Select all
output=openglpp
scaler=tv2x
The screenshots show a 2x pixel-perfect scaling over a 2x TV scaler. Is it what you need?

Nice screens! Yes, i think that it's ok now (i'll check it with 1920x1080 resolution)

I don't know if more scalers are needed or not... (for example tv4x, tv5x)

for now i'll try it with scaler=tv3x (this for 320x200 games)

I have not published that version of the patch yet. Keep an eye on of thread of the patch and please ask all questions there, because this is a generic feature-request thread. Edit: openglpp is now available in my patch.

Can DOS box emulate the CT1747 chip? This is the ASIC on the retail Soundblaster 16, not the version that came with Dell computers.

The Yamaha SoundEdge, thinking clearly, is like the SoundBlaster Pro 4.0, with an OPL4 chip.

Rex Nebular, on YouTube, sounds like a SoundEdge, so the emulated CT1747 chip should sound better, and on a game with soundblaster 16 compatibility.

The CT 1948 is the PCMCIA synthesis chip for Windows.

Not sure if anyone else is interested, but bicubic and/or Sinc/Lanczos based scaling would be interesting too.
