For System 7.0 - 7.6 - Mac OS 8 - 8.1

This tiny utility application, is intended for 680x0 Mac users. It removes the PPC Data Fork of a FAT program's file, removing the PowerPC code & saving disk space (about 40% of the size of the fat application file). It removes the unused (& unrequired) PPC code from FAT Macintosh programs, if your FAT program is intended for use only on 68k Macintosh computers.

I've found a use for this software where it wasn't intended to be used. - On PPC SheepShaver.

On SheepShaver, certain PPC native apps will not run (likely because of the lack of a native PPC MMU in SheepShaver). I have found that if there is a native 68k equivalent of the problematic PPC application, there is a good chance that the 68k equivalent will work OK on SheepShaver.

For example: Macromedia FreeHand 7, this version of FreeHand installs as a FAT binary. It also crashes SheepShaver badly and will not run well - if at all. I used Fat Free to remove its PPC code and now FreeHand 7 runs stable on my SheepShaver install - as a 68k app. - OK, it's no longer a PPC app, but to me, this is preferable to not being able to run at all. YMMV.

(v1.2.2)

Compatibility
Architecture: 68k

SSW 7.0 - 9.x - a native 68k app, runs fine on PPC.

Very basic operation:
Simply locate your program to "unfat" & click OK. It's fast & takes about 2 seconds for a large program to become PPC code free.
There's no user feedback for when its done "unfatting" an application - so don't wait around for "Fat Free" to tell you it's finished. Count to "5" and you'll probably be safe Wink

Required:
Any Mac running SSW 7.0 or higher, with 16 KB free on Hard Disk and 50 KB of RAM to run. It won't run under Systems prior to SSW 7.0 - Increase the memory allocation for Fat Free if it fails with a "Not enough memory available" type error.

Note:
Only use this program on a copy of the application you intend to use for PPC data fork removal.
