Trouble with Software in Qemu [MacOs9.2.1]

Post by AnonFriction »

Hello!

I've been trying to use Qemu with MacOS9 to run the Marathon games and their editors. When attempting to launch any of the Marathon games I get an error message "Sorry, Marathon requires a 13" monitor (640x480) or larger which can be set to at least 256 colors or grays." ID=-1

Was hoping someone here might know how I can fix this! I have it set to 1024x768 but I still get that error :(

I've included my qemu.bat contents below

qemu-system-ppc.exe -L pc-bios -drive file=MacOS9.2.1.img,format=raw,media=disk -boot c -m 1024 -M mac99 -prom-env "auto-boot?=true" -prom-env "boot-args=-v" -drive file=MacOS9.2.1.iso,format=raw,media=cdrom -drive file=Marathon.iso,format=raw,media=cdrom -sdl -device usb-mouse -net user -net nic,model=rtl8139 -g 1024x768x32

Thanks!!

Hi,

-g 1024x768x8 should get you 256 colours.

Best,

There's a version of QEMU with the VGA driver. Without it, not only will you have to manually specify 256 colors mode, but it won't display properly (it will display as series of jumbled up black-and-white colors, even if you specify Colors rather than Grays/Greys).

The -g 1024x768x8 worked!

I still need to grab the version with a vga driver, but thank you both for answering my question!!
