Yeah, I didn't ever try messing around with Missingno. I heard it could screw up the game and I didn't want to lose the team of level 100s I spent quite a bit of time training, but I could see where people loved having glitchy fun with it and how it ended up even making its way into some horror Pokemon fan fictions.

It would be a shame if the 3DS eShop versions took the glitches out. Those are a vital ingredient to the nostalgia.
