Castlevania II: Simon’s Quest (NES - Konami - 1987 - USA)

Castlevania II: Simon’s Quest (NES - Konami - 1987 - USA) When I bought this game in the mid 2000 and try to pop it into my NES, I always had the same issue: the title screen was flickering et rebooted endlessly. I thought that the cartridge was brocken, put it back on the shelf to never play it again. It is just recently, when taking this picture actually, that I realized I’ve bought an American copy of Simon’s Quest... No way it would play on my PAL NES ! So the question is asked: is this game worth rebuying? IMO I’m not so sure.
