The store had 4 distribution machines (PCNYa, PCNYb, PCNYc & PCNYd). Whichever you put it in, was what the OT was. Then it added one, so depending how early/late I went in the week (Friday was usually the reset day, I think), determined the ID.
In the GBA days events happened so rarely, that there wasn't really a community to it, but in the GBC days, you had a good amount of people going, playing and getting what they could. When the company is more active, the community is better and more supportive!
