Clarification: BeOS PPC uses PEF (because that was the main format MW supported, there was a lot of Apple knowledge in the building and there wasn't a better exe format for PowerPC at the time.) The offshoot of this is that some of the software from PR will run on R5.03. (preview release, for some reason the first 2 public releases were called PR(1) and PR2, with AA (advanced access) being almost PR1, but not quite baked.) One of the things I managed to get working was the MW Java - it was horribly out of date, but it was pretty cool to mess about with. Intel used PE for R3, then ELF from R4 onwards. So R3 Intel software is not compatible with any other release. No idea what the Hobbit BeBoxen used. BeIA used ELF or CELF, the latter being a customised ELF exe format with compression of symbols and stuff like that to reduce on disk size.
