I've heard that the first batch of Kirby & The Amazing Mirror on Game Boy Advance (US version) contained glitches that could stop you from beating the game 100% and in worse cases even erase your saved data.

I can understand bootleg copies containing glitches like that, but in the same paper I heard about Nintendo issuing replacements for those with dodgy copies.

Anyone know about this, and anyone able to tell me how I can ensure I get a non-glitchy copy?
