Not only this, but a working, binary compatible version of AROS on real Amiga's is pretty much the holy grail for determining how compatible AROS is with real AmigaOS.
I did a bunch of work to the console.device and console handler in AROS recently, and to debug incompatibilities with AmigaOS I had to spend a lot of time getting really old AmigaOS example code compile with AROS on x86. With AROS running fine on m68k Amiga's, I could've gone straight to running Amiga apps as test cases.
Getting it running should help us fix a lot of bugs and incompatibilities that will benefit AROS as a whole
Indeed. MorphOS started with creating a static 68k emulation and running the original KS ROM. Then each module were replaced one by one with PowerPC native versions. This allowed us to run original 68k apps and identify and fix bugs and incompatibilities instantly. This is something AROS hasn't been able to do before (except in limited fashion thru AfA).
There's no question that AROS has thousands of issues that never have been fixed before. Hopefully the author won't get too frustrated.
To help avoid the frustration I'd recommend using the same method MorphOS used: Take original KS ROM and replace components one at a time. This will help debugging a lot. You can easily switch between original and replacement modules to see where some issue might originate. Eventually you wil be able to get rid of the original KS ROM completely and run on your own.
