Re: Free, Non-Apple 68k MacOS Implementation(s)?

I've been continuing to work on this, and have something pretty basic up and running, within PCE. It only displays a bitmap image, however it does so without the use of any Apple-copyrighted code. The program is loaded into PCE as a rom file. Here is a screenshot: https://user-images.githubuserconte...

Re: Free, Non-Apple 68k MacOS Implementation(s)?

Good thought. I forgot that PCE had Mac emulation in it (despite having hack-ported it to another platform, at one point!) I have PCE building + running now. I don't, yet, have source-level debugging enabled for it yet, despite it being compiled with both CFLAGS and CPPFLAGS having -g set for config...

I've been doing a bit of digging into this. Here's what I've done, and/or figured out, and/or made mistakes with ;-) : 1. I tried getting Executor building in OPENSTEP/m68k, without any immediate luck. I was able to get a working, OPENSTEP/m68k system running, and with Developer Tools installed, how...

Re: Free, Non-Apple 68k MacOS Implementation(s)?

Like WINE, it could also have a second mode where you could compile against it. Imagine writing some code in Turbo Pascal in BII, and then linking it against an XCode project.... I like this idea, although, it seems like it would expand the layer's target by quite a bit. My current thought was more...

Re: Free, Non-Apple 68k MacOS Implementation(s)?

Here is a new, somewhat broad question, on the same vein:

Would a freely-redistributable, open-source reimplementation of 68k MacOS be useful to anyone (besides myself, potentially)? :-)

Re: Free, Non-Apple 68k MacOS Implementation(s)?

I think the first steps would be understanding the 68k port and verifying we can build and deploy for the target (or possibly for the Previous emulator if that supports 68k). Using the Previous emulator to confirm 68k hosts seems like an interesting idea. I've yet to try Previous myself. When I fin...

Re: Free, Non-Apple 68k MacOS Implementation(s)?

Executor side-steps all this in the same way WINE does for Windows: by implementing hooks to the toolbox calls itself and running the code natively using native CPU operations. This meant that Executor had to do endianness translation and other hackery on the input data to make it usable in an x86 ...

Free, Non-Apple 68k MacOS Implementation(s)?

I've been wondering to what degree it might be possible to have a freely-available, open-source, non-Apple implementation (or implementations) of the 68k MacOS, one that could be distributed freely to users, perhaps alongside one of the several, 68k Mac emulators. I recall that Executor, in particul...

Re: Running on Fedora

This looks like a bit like a JIT-related bug that I saw recently, whereby a 1 MB Performa ROM was leading to a crash, but only when JIT was enabled. Are you sure that JIT is turned off? To double check, try adding "jit false" to your Basilisk II prefs file (probably in ~/.basilisk_ii_prefs).

Re: Work in progress by David Ludwig: BasiliskII port to SDL

Precreated images might make sense. I do see a lot of those floating around already, though. The extra importing step(s) do concern me a bit, in terms of UX. A working Basilisk II setup is, as far as I am aware, a set of files, including, at minimum:

1. rom file
2. prefs file
3. disk file(s)

I'd be willing to put in time to investigate why the GTK UI might not compile with the SDL2 port, however, I am hesitant to spend much time redesigning, or significantly augmenting it, beyond, perhaps, tweaking it a bit, say with regards to differences in parameters. I.e. I might agree with you, alt...
