256 Color Mode
Posted: Thu Nov 02, 2017 12:30 am
Hi, I'm new to Qemu.
I loaded Mac OS 9.2.2 with Qemu (Sept. 16 2017 release), trying to play a game. When I clicked on the game, it gave the message:
"Monitor cannot be set to 256 colors. Requires 256 colors to run."
I tried cutting the color depth with the -g option with:
-g 1024x768x8
But that just forced everything to grey scale.
In the Monitors Control Panel / VGA Display panel, the only color option is 'Millions'.
I am working on Windows 10.
I saw this post: http://www.emaculation.com/forum/viewto ... 775#p53469 but I cannot figure out what I would be missing. Seems like all the changes listed there should be in the current release.
Here is my command:
qemu-system-ppc.exe -L pc-bios -boot c -m 256 -M mac99 -prom-env "auto-boot?=true" -prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -drive file=MacOS9.2.img,format=raw,media=disk -device usb-mouse -device usb-kbd -sdl
There are some warnings:
(In the emulator)
MacOS: unable to find a usable NVRAM partition - using offset 0x1400
(Terminal)
Trying to write invalid spr 0 (0x000) at 00f113c0

Any ideas to get 256 color support?
Edit: Oh yes, using OpenBIOS v1.1
