alt Hacker NewsThis reminds me of the Action Replay device you could get for the Amiga 500 in the ‘90s.
You could use a knob to slow down any game to a stop. You could also press a button to go to a console that let you change memory.
It would even figure out which bit of memory kept the number of lives of you deliberately lost a life and it could see what decremented.
There was some cheat software that did the same back in the windows 9x/XP days. Dont remember the name but there were many I am sure.
