Hello everyone, as you may or may not already know the makers of Dizzy games published on the internet (for free) the finished ROM of a game from the 90's - Wonderland Dizzy for NES.
Did anyone tried to make a cart from it?
It's a 256kB PRG UxROM type so I tried making one using UOROM board since it's the only one that supports 256kB. The game boot fine but it hangs after playing about 20 minutes (about 1/3 of the game).
Any ideas?

Here's the official site where you can play the game and get the rom for free (found after selceting "click to play"):

Is that ROM playable on a powerpak?

It's more likely that Wonderland Dizzy uses the same mapper as the other Codemasters games.

Yes, it's playable on flash carts.

Other Dizzy games use mapper 7 (AxROM), this one use mapper 2 (UxROM) according to Nes Mapper Reader.

 

Could be some kind of protection?
