Hi
I'm trying to promote PAL screens to CGX screen, with mode pro. I just can't get it work :(
I can promote to dbPAL but that doesn't help, because my monitor can't display it.
Any ideas?
-
Some programs just don't work with CGX/P96. They open the screen only to allocate gfx memory and then access the (chip) RAM directly. That's not possible with CGX.
-
Can MCP do it?
-
Nope
Programs that I tried to promote were real3d 1,4? and scenery animator.
IF I can't promote those to CGX screen, what would be my choises when dbPAL doesn't work with my monitor?
-
What does work with your monitor? What are it's specs, what can it support?
-
horizontal: 24 - 83 KHz
Vertical : 50 - 76 Hz

Vertical : 50 - 76 Hz
That could be why it doesn't hold DblPAL - that mode is slightly less than 50Hz.
Can you live with DblNTSC - use Overscan to increase the screen size and you don't lose too many lines, it runs at 58Hz iirc. Will VGA/MultiScan work? I think it's supposed to be designed for "normal" PC monitors...

"Programs that I tried to promote were real3d 1,4?"
Why not use a driver for a CGX-screen directly from within Real3D?
I don't know which versions are supported, but I was thinking of something
like this http://aminet.net/package/gfx/3d/wfmhcybergfx.
Some of the handiest screen-promotion tools I've used are NewMode and
ModePro, but I only ever used it for promoting games between PAL/NTSC.
I do not think they will work for the purposes you intend them to though.

Version wich I use doesn't have tool to choose screen mode

First of all, only programs that use intuition.library functions to open a screen can be promoted in ModePro. For the programs that can be promoted...
You need to create screen resolutions (modes) for the gfx card that match the resolution of the screen you want to promote from in ModePro. For example, If the native Amiga screen is 640x256 then create a 640x256 mode for your gfx card. Then promote to this screen mode. This works 90% of the time in P96 (cgfx should be similar). If it still doesn't work then try setting planar bitmaps in ModePro. This will fix another 5% of the programs but is slower so don't use on all programs. For the last 5% of the programs, good luck ;).

what concerns real3d it can open environment on gfx, you can save it as a project and start from there not to have it open on different screens, also the rendering driver for gfx come in handy, but there are two (?) windows in real, animation control, and palette if im right that always want to open on aga. i think this is the most annoying part.

You can promote most AGA modes (not HAM8) with ECS, a graphics board, P96 or CGX, and ModePro if intuition.library, graphics library, and layers.library functions are used. Any program that touches the hardware (e.g. the copper or blitter) will likely fail. Programs that write directly into their screen gfx/bitmap memory may work with planar bitmaps activated in ModePro. Most games hit the hardware and fail but a lot of Apps can have their AGA modes promoted.
-
I made a brief trial as I happened to have Real 1.4 on my HD. Using ModePro with Picasso96 GFX seems to work - I promoted via program name to RTG screenmode. But not sure if every aspect works. So CGX should work as well.
-
I get those work, thanks for advises :D
SimCity 2000 I remember that screen promotion worked with P96 and modepro.
Any hint how I get it work with modepro and CGX?
-
Try ModePro with force planar option - no idea if it helps but with SysInfo it did...

Yes, that's the option I was talking about when I said use planar bitmaps. It orients the bitmaps on the gfx card much like they were with ECS/AGA.
