Hardware ROMS or not, you can still Kick the ROM into Fast Ram. Drawback is you loose 0.5Mb of Fast Ram but the bonus is your WB is an awful lot faster for doing so! ;-)
Most kick programs I know need the use of an MMU from inside your CPU. If you have an LC version of CPU, you might not have a working MMU & consequently, you will not be able to Kick the ROM Image into Fast Ram.
Can anyone clarify if there are Soft Kicking programs that work without an MMU?
