English Amiga Board - View Single Post - Longer gameplays.. saving state (or other trick) on a real Amiga?

It was possible with Action Replay save state but with whdload / modern amigas it's not.

One of the reasons: no way to save the state of write-only chips without dedicated hardware.

whdload can record them if you have a MMU but that slows down the running game and was never exploited for a savestate.

Plus the fact that expansion/whdload memory would have to be the same at each run (using AllocAbs)

Some attempt was made with JST (and some slaves) but never was generalized. slaves had to be reworked to provide more info (basically info on write-only registers)
