That would be a really nice feature, especially for games that do not have "save" option.
There are not many who has hours for playing some old game from the beginning to the end (since most of us are over 30
)
But I do not know if something like that is even possible, since "save state" should save state of the game in Amiga memory (memory dump).
That is possible with emulator, but on real Amiga, I do not know.
