Even BLK4000? He was and is the lord of the fruit machine, a messiah if you will.The stuff you mention there definitely happened in all sorts of various ways dunover, but in the case of Indiana Jones I honestly don't think it's the culprit. (As for compensated machines in general, they are a uniquely strange UK creation, on the one hand they have given rise to some of the most creative, skilful and challenging gambling games ever made, but on the other hand they've been vulnerable to all sorts of corruption, manipulation, trickery and general malfeasance.)
Over at a couple of dedicated fruit machine emulation forums, and indeed in comments left on my previous videos about Indiana Jones, not one single person has ever reported managing to land the Win Series feature on the machine, across all kinds of stake/prize settings, and a multitude of percentage settings. (Including from people who have owned the real machine for years, and state they have never managed to collect the feature.)
It looks like JPM coded the feature in but just didn't leave in any viable mechanism for it to be awarded, but by hacking the RAM location for the hi/lo reel, we did at least prove it exists and the machine can award it, and knows what to do with it, if you can survive the required number of ambushes.
