Mine was Pokemon Rijon Adventures.
I was on my laptop one day when my brother came in and gave me some normal Pokemon roms on a USB. He had gotten it from a friend, he had said. Anyway, in the Original Roms folder, I clicked on Fire Red. Whoever patched it, didn't change the name of the file, which I soon found out. Rijon was cool, and I loved it. Truth be told though, I really want Baro to make a hack where there are much more events in Quartz, and change Govolts to someother Pokemon, coz I wanna battle Ash with Peezgal! :D
