Macintosh (Basilisk II) 8-bit Color

mediamogul

Just tested 'Prince of Persia 2: The Shadow and the Flame' and it runs like a champ with the framebuffer set to 8-bit color depth. A runcommand setting would indeed be most helpful for games that require a higher color depth, as the screen now turns black when the emulated Mac is set to "Thousands of Colors". It's been a long time coming, but it was well worth the wait to play this great game again. I'm marking this as solved. Thanks again @Meneer-Jansen and @BuZz for your help with this.

@mediamogul I made a ticket for myself on the issue tracker. Nice find btw. Strangely I did try switching framebuffer depth before and it didn't work. I obviously did something wrong or a firmware change has affected something. Nice one!

Got this all working today with a "1gb hard drive". Now i notice on the pi the mouse skips. Which makes using paint impossible. Closing stuff gets to be a pain too. Is it possible to have the mouse working a little better? On windows obviously it is flawless. Im going to install doom for fun just to see how bad it runs.

@edmaul69

The mouse doesn't skip on mine for whatever reason. I've even tried it with a few mouse-based games and it's pretty smooth.

edmaul69

@mediamogul strange. I have it with a premade 30mb drive and the 1gb one i made. The skip is so big that the blue squares on the background are slightly smaller than the space between each mouse jump. I watched a youtube video where the guy had the same issue.

@mediamogul also this is on os 7.5.5 with several performa roms and a quadra 650 rom. On a pi 3 i might try a fresh install as i used the files from a premade image.

@mediamogul well i found out the issue. for some reason it does not like my apple iie mouse. hopefully i can figure the issue out. i even play all my doom mods with this single button mouse. i ended up making my cfg like yours except that i have my ram up to 138412032. thanks for the help.

edmaul69

I just tested and it actually skips in everything. Just never noticed before. This suxx...

Hah! Too kool.

Maybe it's just getting gummed up. It is one of the old ball-type mice right? Is it easy to take apart to clean?

@mediamogul i am having trouble trying to install os 8 on basilisk ii on windows. I have an os 8.0 iso as my cd rom drive, 7.5.5 recognizes the files. But using the 7.5.5 image or a fresh image i cant get it to work. Are you able to tell me which rom you are using? Ie: quadra 900 (might have a much longer name) and cpu type. And are you choosing to boot from cd when it is launched? I get a black screen if i dont and i get the checkerboard screen if i do but windows immedietly has an error and crashes.

Edit: with a blank hard drive and the os 8.iso as my cdrom drive choosing to boot from cd rom if i use the quadra 650 rom i get told about the startup disk wont work on this mac. But it brings up the b&w screen but then immedietly crashes if i try the quadra 900 rom. Im not sure how to get the basilisk on the pi to force boot the cd to see if i can install it on there. You said you used a performa rom. Curious about that.

@edmaul69

I setup my installation last May, so my memory on the details is more than a little hazy. However, looking over my backup files, I appear to have actually used a Quadra 900 Rom and a MacOS 8.1 install ISO.

edmaul69

@mediamogul ok. I will try to find the 8.1 install instead of the 8.0.

edmaul69

@mediamogul so right now with quadra 650 and 7.5.5 hard drive on the pi it is letting me install os 8 so i will see how this goes....

edmaul69

@mediamogul Do you know if doom is an 8 bit or 16 bit game? I will definitely try this workaround you posted here. I might have some questions on how you did it, but i have to wait until 8.1 finishes installing.

Well i found my issue on windows, i was using basilisk v1 and switched to v2 and it worked!

mediamogul

@edmaul69

Nice.

edmaul69

@mediamogul so i put that info in the runcommand-onstart.sh in the /opt/retropie/configs/all/ like this:

# the line below is needed to use the joystick selection by name method
bash "/opt/retropie/supplementary/joystick-selection/js-onstart.sh" "$@"

if [ "$1" = "macintosh" ]
fbset -depth 8
fi

and then i made a runcommand-onend.sh and made it executable with this:

if [ "$1" = "macintosh" ]
fbset -depth 16
fi

and it still crashes

mediamogul

@edmaul69

Does it actually crash, or does the screen go black and stay that way? Also, BuZz corrected me that the color depth should be restored to 32 on exit, rather than 16. I'll change it above also.

edmaul69

@mediamogul it actually crashes. Then i have to restart the pi. Does that with and without the code

mediamogul

@edmaul69

There must be something wrong with the install. That code only sets the framebuffer color depth. Even without it, there shouldn't be a crash, just a black screen.
