Pretty much all the problems are caused by the game running to fast on modern systems, after i used "mediator" to inject post-process effects into the game ( btw mediator detects dx9 but is wrong the game is dx8) and made it run much slower the game worked fine, no more being unable to change worlds, no more sherkiness and all buttons worked fine like the feeding button, etc.
