Hopefully this is the correct place for this.
So, back in the Summer/Fall of 2001, Celebi was given out at various Six Flags locations as part of the Pokémon Fun Fest. The Celebi that I got from the Agawam Six Flags was still on my copy of Crystal when it died.
This is probably a long shot. I'm wondering if anyone has any save from GSC that still has a legit Pokémon Fun Fest Celebi on it?
Likelihood any of these savefiles are all long dead. Gen II events that aren't in Stadium, or already privately dumped, are lost for good.
I think if someone on this forum had one they'd be willing to contribute, they would have come forward already.
If you need more help you can see the Tutorials section. There are some other options you can choose from. However members recommended the best options above.
3. Can modify "Base EXP" individually, or can downscale them all on the "Enhancements" tab.
(Modify all EXP Gain)
4. You can compile the program with Visual Studio Community 2017
1. Nobody knows where they are stored in the game data.
2. These species can't spawn in the overworld; nobody knows why.
3. Change exp yield in personal data, or edit the EXP threshold tables (grow_0*.bin) manually.
4. Files aren't compressed; they're copied to a separate folder which is set up to be used with layeredfs on atmosphere/etc.
