Macintosh (Basilisk II) 8-bit Color

[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

@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.

[edmaul69]

@mediamogul i will try another virtual hard drive i made.

[edmaul69]

@mediamogul so i did a fresh install of 8.1 (no update this time) uninstalled and reinstalled basilisk. No luck. Crashes everytime i switch to 256 colors. Even if i go directly into the monitor settings on os 8.1. But hey! If it means anything i managed to get the whole pi stuck in 640x480 256 so i could keep going back into os8.1 without rebooting. Lol

@edmaul69

At this point, the only difference between our two setups is the amount of allotted RAM. Is it possible that's the issue?

[edmaul69]

@mediamogul nope i just tried that. A possible fyi with 132 megs of ram after i changed my colors to millions (32bit) after restarting it would load os8.1 but the desktop icons never came up and my cursor was stuck on the watch not allowing me to do anything. Once i switched it to 256megs of ram (268435456) it booted right up.

[edmaul69]

@mediamogul also can you post the contents of your emulators file? Also are you just using a dummy start.txt file or did you modify it?

[mediamogul]

@edmaul69

emulators.cfg:

basilisk = "/opt/retropie/emulators/basilisk/bin/BasiliskII --rom /home/pi/RetroPie/roms/macintosh/mac.rom --disk /home/pi/RetroPie/roms/macintosh/disk.img --extfs /home/pi/RetroPie/roms/macintosh --config /opt/retropie/configs/macintosh/basiliskii.cfg"
default="basilisk"

start.txt is just the standard dummy.

[edmaul69]

@mediamogul yup. Just the standard info.

[edmaul69]

@mediamogul so in your roms folder do you have anything besides your system folder, your rom and your img? Not sure if there was anything else you added there that it needed. Of course im sure you dont know of any else you had installed (as possibly mentioned by @Meneer-Jansen )

[mediamogul]

@edmaul69

Nothing else has been added. Will Basilisk launch for you without changing the color depth?

[BuZz]

Check your dispmanx settings for that emulator.

[edmaul69]

@BuZz when i turn dispmanx on just now all i get is a black screen. Cannot exit blindly either

[edmaul69]

@BuZz i also havent updated linux kernel since either 4.0 or 4.01 because i use the northwest controller fix and was too lazy to do that again if that matters any.

[BuZz]

@edmaul69 it might help - at least to match your set-up against @mediamogul's

[edmaul69]

@BuZz i will do it then.

[mediamogul]

I'm going out for the night, but I do have something to add to this before I leave. I've noticed that one in several instances of launching Basilisk II with an 8-bit color depth leads to a black screen on my setup as well. Once I noticed it, I continued to cycle through launches, trying to estimate how often this happened. While admittedly not scientific, I'd say that I get a black screen about one out of ten or so launches. Could this be the outside script not launching in time on a few occasions? I'm certainly not qualified to say, but I thought it was worth noting.

[edmaul69]

@mediamogul so a couple questions, is dispmanx supposed to be on or off? What are your runcommand options on boot? Are you using a buffer size or a specific display size?
