[Re-Catching Legendaries]

So, I pulled through the Anomaly Kiogre fight, and I realized I just had 2 Ultra balls. After desperately trying to catch it, I just ended up killing it with a stray crit, and I can't go back for a retry because I forgot to save. Can I find it anywhere else?

 

[LF Gothitha and Claw Fossil]

Please, I just need those two pokemon to complete the Dex quest, and I'm running out of mining stones. I have every other pokemon so far, so I'll trade for anything,

 

Please help and thank you.

[Lookin' for a Ditto]

Hi! I'm looking for a ditto with good IVs. I've been resetting for days, and I just want to get out of this damn factory. So any help is much appreciated.

[Help starting up the game]

As the title says, everytime I try to start the game up, it crashes and goes to black until the 'RGSS error' window pops up. Any way I could fix it?
