No Commodore but real USA
AmigaOS 4 is fully recompiled AmigaOS from Motorola 68k code to PowerPC. Any software that is system friendly and can open a Workbench windows works out of box or with minor setting tweaks.
Thanks to Petunia, 68k JIT, a core AmigaOS 4 component in Kickstart
old 68k software works unemulated blazingly fast.
So recently, an old Amiga raytrace veteran Mike Brantley has demonstrated Lightwave working on OS4
Also, and old veteran, Image FX simply works
True step forward – AmigaOS 4
Thanks Mike!

TimberWolf is a bounty funded project to port Mozilla Firefox to AmigaOS 4. [1] It was started in early 2009 as parallel to AmiZilla project that has the same intent. Amizilla had a more complex history, as it was started in 2003 from US firm DiscreetFX with the target of porting any running version of Mozilla engine based Firefox compatible browser to Amiga platforms. As long as Amizilla project was too ambitious the project was closed on November 19, 2009 without producing significative results. Timberwolf project is full managed by Thomas Frieden and Hans-Joerg Frieden (AmigaOS 4 core developers), who work at it as a spare time project. The first release has been made public in June 2010.
