tsrtrocse :
you cannot really use the software alone - what you really need to make real-time changes is an emulator and the matching software comes with it. there are several available and if you do need it for a cosssie (hope not the eec-version), then it might be rather inexpensive since they use the old DIL format chips (27C128 or something small like that) and are 8-bit.
One of the most reknown chip-tuners is running this forum, i might suggest if you really want it to contact Stu on here. Also my knowledge might be well outdated, i stopped chipping a few years back.....
cheers,
michael
