1 Koin was a full clear in mk1, mk2, umk3 for every oldschool mk fan and arcade junkie in general, these games are scripted like no other fighting game, and i loved it that way, it almost felt like art playing MK2 in an arcade lol.You need to know the game and its mechanics inside out to "master it", there is little difference between the arcade difficulty settings in a genuine machine and how the CPU reacts, what most people don't know however is that in a genuine arcade port MK2 choosing p1 or p2 after you insert your koin matters ALOT, the CPU completely changes it's playstyle going from semi-exploitable and very cheap p1 to very fun to play and fully exploitable in a lot of ways (if you know how to) p2.
Mk1 has a very similar exploit with p2 but has a smaller window for you to execute it, you can tell it's almost the same engine/cpu, umk3 has lots of ways, for ex. if you're having trouble choose scorpion on hardest, the cpu reacts universally with either running towards you for a combo/rushdown, that's when you jump back and air throw, the other one is he will just stay there at double sweep range, that's when you jump towards him, air teleport punch before he has a chance to air kick you, you'll juggle him in the air-> spear-> bnb combo.
I still know almost every aspect of all these games from my arcade days, i bet a lot of you do to and it's a very fun experience overall, especially with an arcade stick.
I'm refering strictly to the one true arcade port which is MAME or the original cabinet, mkak is a piece of crap, i won't take anything less than arcade perfect for these games and this compillation basically has no target audience, the oldschool mk fans think it's crap because it isn't arcade perfect, and the new fans have mk9, it's a pretty strong difference and most wouldn't play these games for more than 5 min considering its..let's say "complicated" AI/terrible online etc.
If mame can do it, so can NRS/WB.
