So I got this on Virtual Console the day after I made my post in this thread and played through. Was really fun and nostalgic. I was glad to see that even though it's been like 10 years I'm not too old to think the cutemons are adorable when I give them apples and they're all like YEAAAAAAA FOOD ^______________________^
I was kinda surprised how much I remembered, too. Got all but 3 Pokemon pictures while I was going through, and two of the three I missed I failed to capture just because I couldn't aim Pester Balls (Growlithe, Arcanine). The only one I legitimately forgot how to get was Gyarados, though I did half of the lead in to evolving the Magikarp in the run through of the course to get the Pokemon sign so I think I remember enough that if I go through again I can get it without outside help.
Still a really fun game!
