Some Amiga 68K programs require the Classic Amiga chipset or some stuff from AmigaOS 3.1.
I think Brilliance 2.0 might be one of these programs. It crashes immediately if I try to launch it directly on OS4, but it is quite happy with AmigaOS 3.1 running on the OS4 PPC version of E-UAE. I use an older version of E-UAE than the one distributed with the latest version of OS4. Just haven't got around to upgrading to the newer version of E-UAE.
Just to clarify... I tried Brilliance 2.0 only. Brilliance 1.0 uses a dongle.
Final Writer 97, Cloanto Personal Paint and TVPaint run fine directly on OS4 and do not require E-UAE.
