MK3 (At Games) bug

So I recently found my At Games Sega Genesis and decided to try it again but every time I tried doing the Ice Slide it just wouldn't do it. Anyone else having the same problem. Also the og controllers for the console broke so I bought some cheap Old Skool controllers. Is the console the problem, controller, or both?

Also I don't have the budget to buy an original Sega Genesis are there any clone consoles close to it I could buy at least around $50 or $110?

Edit: I'm going to archive this soon since my dad gifted me a Sega Genesis and 2 Mortal Kombat games (MK1 and MK2). However, I still wanna know if the at games console has a problem, the controllers, or it's both.
