RTG games in window (Overlay/PIP), under WinUAE?

[Ponki1986]

Hello. Maybe the topic has already been discussed, so I'm sorry if I'm duplicating it.

I want to ask if there is a chance that RTG games could ever be launched in window on the Workbench, under WinUAE?

I know that the UAEGFX driver does not support PiP, but maybe someday it will change.

[AMIGASYSTEM]

It does not depend on WinUAE but on the Game, however there are many RTG games that work in Window, HERE I've cataloged more than one.

[Ponki1986]

Yes, I know about it, if the game does not support window mode, then you will not be able to play in the window.

But I remember the times when I had A1200 with Blizzard 1240 40MHz, Zorro II and CV64/3D, then games like Foundation, Doom and if I remember well GeneticSpecies I could play in the window.

You can also play on WinUAE in the same way and even faster

Does Picasso96 support that kind of overlay? (Not just YUV video overlay). Or did you use Cybergraphics? (which can't be implemented because SDK is not public)

[AMIGASYSTEM]

Toni what did you refer to in particular?, i do not use Cybergraphics because it does not work well

And this has nothing to do with OPs request or my question! (uaegfx cgfx support)

Try to stay on-topic please.

But how? When I run even Foundation Prefs, I can not choose the game mode in the window.

Unless I'm doing something wrong. There was a moment when GeneticSpecies did not see RTG libraries, but I fix it.

I now use Picasso96, I had CyberGraphX on CV64/3D.

[Toni Wilen]

So it most likely is CGX feature only. (P96 has some kind of YUV video overlay which is not implemented in uaegfx)

Note that you can use CGX with any supported hardware emulated graphics boards but VGA chip overlay is not (at least not yet) implemented in UAE.

It may get implemented if there is simple test case (video player is NOT acceptable!)..

[Ponki1986]

Ok. Thanks for the answers.

Sorry Toni unfortunately Google Translator does not help much to understand, i understood something else


@Ponki1986
With the Doom games you can to play in the window mode

[Toni Wilen]

Yeah, that can make it difficult to understand

-

Perhaps some programs have built-in Picasso96/CGX overlay support? (but again, if you want help me to implement it: rule is still the same: "program" must not be a media player! Playing videos in emulated Amiga is far too pointless. EDIT: Amiga ports of PC games are practically in same category too..)

[AMIGASYSTEM]

Sorry Toni, technically i do not know how it works, as you can see from the screenshot DoomAttack allows you to play Doom in Window

This is nothing special. RTG games can support windowed mode but using overlay adds some nice extra features compared to fullscreen/overlay mode:

- overlay can support scaling for free. (This is very useful for video players)
- overlay can support different color depths (overlay can for example use 16-bit mode when WB is using 32-bit mode)

Overlay is basically separate "fullscreen mode" overlayed in top of normal screen, position and size can be freely chosen. Overlays were supported in hardware in most VGA chips. Later models used 3D hardware to do the overlay and dropped the hardware level bitmap overlay support.

Ok thanks for the information

Genetic Species requires PiP, but Foundation Gold should work.

If you have a fast system you could try ScreenInWindow:

Some screen formats do not work properly, but it works for some games, like Crossfire II and Nightlong:

Well apart from Genetic Species there is:

ShapeShifter

http://aminet.net/package/misc/emu/PippinEVD

Blurscope - AmigaAmp plug-in that only works with PiP

http://aminet.net/package/mus/play/BlurScope

Xami - X11 server

http://aminet.net/package/misc/x11/Xami

Singularity is Just The Begining - Scene demo

http://aminet.net/package/demo/aga/sgr-begi

XIII - Scene demo

http://aminet.net/package/demo/aga/xiii-Oxy

Genetic Species uses rtgmaster.library with the rtgpip sublibrary

http://aminet.net/package/driver/video/rtgPIP

Other software that uses rtgmaster might also work but it needs to be coded for it.

Chunkyppc.library also supports PiP, so games like Crossfire II should also work.

Thanks. This seems to be very good test case, no extra dependencies or extra configuration needed, it simply tries to open overlay window.

[Toni Wilen]

Quickly done. SGR-Begin works now in PIP mode when using uaegfx. Usual winuae.7z url.

No color keying yet. I assume overlay should get hidden if some other window is moved on top of it. EDIT: now implemented.

Only high and true color RGB modes supported. I need easy to use test case for YUV (video) overlay support. Not a video player please..

Pure software linear scaling. I am not going to improve this.

If something is not working: winuaelog.txt is required.

EDIT: PicassoIV hardware emulation overlay is now supported.

[Toni Wilen]

YUV (both Y4U1V1 and Y4U2V2) overlay mode should work now, at least in theory..

It is probably quite slow due to slow non-optimized per-pixel YUV to RGB conversions. It will be replaced with table based conversion when this version is first confirmed working.

Nice!

BlurScope working:
