For now if you compile it with the patch, just change the two "#if 1" to "#if 0" in jaguar.cpp
It should not be hard to add an option to the config file.
The whole first 8MB of jagMemSpace is saved in the state file.
Maybe only the first 2MB of actual RAM is necessary, but if everything is zeroed at startup then state files can be compressed to about 1-1.5MB
I just checked, and if you zero everything at startup, then randomize the 2MB of RAM, it only adds a few hundred KB to the state file.
