User name "moulinaie" from AtariAge gave me a link to a Atari ST software that lets you patch PRG programs to run in the FastRAM.
Here it is: http://www.umich.edu/~archive/atari/Tt/flgset.lzh
I patched 2 programs and and it seemed to load. One of them was MTPro32 (Midi software) and other CAD3D. The MTPro32 froze after loading, probably do to none existing MIDI support. The CAD3D loaded and worked until I tried to do View->Superview and then froze.Other then that it works.
This is on A1000 NTSC, with 256KB free ST-RAM and 1.5MB free Fast-RAM.
