This is REV A of Crystal, where everything is the same, except that I have enabled the Celebi Event. Go to the Goldenrod Pokemon Center to get the GS Ball!
It's Nintendo's official Celebi Event that is triggered when you enter, then exit Goldenrod's Pokemon Center for the first time. You will receive a GS Ball that you take over to Kurt in Azalea Town, just like the Japanese version of Crystal. You then take it to Ilex Forest, and place it in the forest shrine and... Celebi appears!
Nintendo never released this event on the English version, until I restored it. Nintendo of Japan really screwed us over. I mean, it took minimum assembly to do this and a flag change in events. We never even got a chance to receive this promotion.
Patch it to a clean ROM, called: Pokemon - Crystal Version (USA, Europe)(Rev A).gbc
