I do have quite a few event save files, assuming you're referring to GBA save files? I don't think there's anything you can offer for them really though as they're quite valuable. But on save file I have: complete GCEA fukuoka/nagoya/osaka/sapporo/tokyo/yokohama, complete JEREMY set, ageto celebi, some hadou mew/regirock/regice/registeel, festa metang, rocks metang, comeplete 10 ANIV set, loads of Rubii/Safaia zigzagoon, tanabata jirachi 40707/50707/60707, negaiboshi jirachi, sunday wobbuffet, MATTLE Ho-oh, pokepark mew/celebi/meowth, 625 unhatched pokebox skitty/zigzagoon/pichu/swablu (thanks to Aglid), 625 wishmkr jirachi (thanks to ShinySephiroth), over 40 unhatched PCJP03 bagon/absol/ralts/pichu, over 60 unhatched PCJP04 poliwag/oddish/meowth/bellsprout, and over 300 unhatched pokepark 2005. Plus Aglid's going to farm a CHANNEL save in all languages soon I think as well. My PCNY wish save is very suspect and I believe is hacked.
I'm after PCNY and PCNY wish on save in particular.
