Other useful questions:
- is Desktop copying itself to the RAMdisk on startup?
- You mention ProDOS 2.4.3; does it repro with 2.4.2?

Yes things are copied to the ramdisk. Also this doesn’t happen with 2.4.2On Jan 24, 2024, at 8:52 PM, Joshua Bell ***@***.***> wrote:

I can repro in MAME (via Ample) using //c Plus and 1.4. I'll figure it out - thanks for the report!

The run basic from here option crashes like the selector does under 2.4.3On Jan 24, 2024, at 9:37 PM, Joshua Bell ***@***.***> wrote:

At least for the shortcut case, the MLI OPEN call in lib/invoker.s circa line 99 is failing with $56 Bad Buffer Address. The buffer is at $800, and the system bitmap at $BF58 is $CF $00 $00 ... $00 $00 $01 which should indicate page 8 is free. This is... weird.

Okay wow, this was quite the journey. The bug requires exactly this to happen:
- An Apple IIc+ which has unique mouse firmware and what I'd consider a bug
- MGTK being used with ROM banked in, which is only true in the Selector (Shortcuts) module, which has fragile code
- ProDOS 2.4.3 which apparently has critical code at just the right spot at $FBB3. 2.4.2 is apparently immune; some memory corruption must be happening but it doesn't cause a problem.
This was a bug in the original MGTK (although 6f08ef6 replicated the code).

The fix will be in the next 1.4 alpha build (end of January).

@samccormack https://github.com/a2stuff/a2d/releases/tag/v1.4-alpha5 has the fix if you want to try it out

Awesome it looks like the selector is working now. I do have a new issue in that I get a crash when it attempts to copy itself to the RAM disk. See attached picture. If you would like I can submit a new issue for this. It copies desktop.system and makes the modules directory before crashing.On Feb 3, 2024, at 12:17 PM, Joshua Bell ***@***.***> wrote:

@samccormack thanks for letting me know about the "copy itself to the RAM disk" issue. Big mistake on my part. I'm pushing out an alpha6 with the fix because it was new in alpha5 and really bad. https://github.com/a2stuff/a2d/releases/tag/v1.4-alpha6
