Then if it is not possible without a gfx card....it is possible with one as we already know..............
Where do you get the strange idea that you could use even one kb more ChipRAM with an installed GFX-card.
so my solution in hardware would be.............create a gfx card thats accessed through RTG I suppose, but isnt a gfx card but only the ChipMem part of it and how it is accessed.
Ah, now I see. You confuse the GFX RAM on an graphicscard with Chip RAM. GFX RAM ist more like Fast RAM, so it is not surprising that there is as (PPC only) CGX driver for AGA.
Though Chip RAM is used to store GFX-data it is only a fraction of it's duties. This part can easyly taken off of the chip RAM, thats how RTG systems work. But it only works for software that goes through the OS.
As for AmigaUAE. Three is an UAE-port for AmigaOS but only the fastest classic PPCs are barely able to reach simpe A500 speed.
Anyway whats the point of haveing more then 8 MB of chip RAM ? You might be able to open more screens in higher Resolution in PAL/NTSC but the chipset wouldn't get any faster, so eventually you could watch at the monitor an see how the screen is updated line by line.
