Even on VBA this game was awfully buggy. Going down to an item or spell felt like I was trying to bench press 5 times my weight. It was...futile. And I'm pretty sure I broke my arrow keys.
On VBA it was even buggier. Infact, parts of the game got corrupted.
Also as to the comment that the European version is bugfree, it isnt. I doubt they even made any changes to the game before releasing it here.
