Mortal Kombat 1+2+3

F10 for options and F1 to start with F2 to add 2nd player. GOG needs to add the original manual or else it is confusing on where to begin. Otherwise, an uncensored version with a lot of charm that can shine if you know your way around a DOSBox config. Best played with a keyboard.

The game are mostly broken, some don't work at all, others don't work with a controller, it's honestly a pitiful re-release.

Does not work, it wont play any of them it can't remap trying does nothing, it wont start games says press start yet no buttons work.

I picked this up for MK3 and it's kinda shocking. You have point five seconds to select your character and if you hit escape for any reason during a ladder it quits back to the menu without saving progress, this has happened several times against Shao Khan and Motaro because I accidentally picked the wrong character in the point five seconds I had to do so. You don't think about these things, the little things like a stop-up panel that says, oh I don't know, "ARE YOU SURE YOU WANT TO QUIT?" It plays solidly (aside from obviously being some kind of 1.0 of the arcade port, there are no autocombos and lots of weird hitbox chicanery) but it's still satisfying to beat if you don't hit escape out of habit because you expect that action to not instantly erase your progress in other games. I'm saying this stuff less to whine and more to warn because I bought this three-pack on sale for a buck fifty and still kinda felt ripped off, look for a port of UMK3

The DOS versions are passable but lackluster. You basically want to use keyboard controls. Some version by Dot Emu or with MAME would be better. MAME is GPLv2 just like DosBox I think. The ROMs would be playable even once Windows bites the dust.
