Hello and welcome Allan!

WonderBoy is an awesome game! I personally rather like its sequel Monster Land for the RPG elements it brings in.
Bubble Bobble bootlegs are full of bugs (enemies not firing and moving strangely). For example, in the bootleg version, you have less than 15 seconds to reach the top of the screen in level 95 or an enemy will block the way and you're stuck (very frustrating).

I think that member
peio72 sells an original Bubble Bobble PCB if you're interested.
