Been playing fruit machines since I was a kid (2p Blue Streaks, Test Pilots etc) but the £25 era was probably my favourite (Vamps, Sharks etc)
Sorry to piss on anyone’s chips but the old ‘123321132’ (or whatever) ‘reset’ code on the Simpsons (and other Maygays) was merely a data dump code for engineers to get the meter readings without having to open the machine up during opening hours. It did precisely nowt when it comes to gameplay and certainly didn’t ‘reset’ the machine. Obviously enough punters and staff thought it was something ‘dodgy’ hence people being banned from arcades.
