Both were running at double speed but I was able to find the gamespeed adresses managing movement speed and animations's speed, so the gameplay feel authentic. Unfortunately, there're still some issues :

- I couldn't find the speed parameter for the "movies" playing ingame, so they're still running at double speed. I'm guessing the parameter must either use a different value from the one I found in the thread or not be located in the allocated RAM.
- It seems that even if the animations's speed was adjusted, there're still some which behave strangely (ex: Near the beginning of ZnK, the train's arrival at the station isn't timed correctly).

I'm assuming there may be some other issues, but the games are still mostly playable. i just hope someone with enough time will be able to research them.
