So over the past few months on and off I've been looking for the demo disc used to patch the berry glitch in Japan. Today I stumbled upon http://redump.org/discs/status/4/sort/edition/letter/i/dumper/LiiZENZ/ which seems to indicate that 3 Japanese Demo discs from 2004 were dumped at some point in time. I have tried searching the dumper's username and the MD5/SHA1 hashes of the discs, but have been unable to find any download links. If anyone else would like to join in on this, it would be much appreciated! Thank you P.S sorry if this is not the correct section!
Interesting stuff, do you know which JPN demo discs were supposed to have the Berry Glitch Shiny Zigzagoon on? It's also possible these we're dumped for the purpose of adding to the re-dump database and never actually uploaded online, however either way we have a SHA1 to search for / compare any found dumps to.
I don't know which ones, but to the best of my research, the berry glitch fix "event" happened at around the same time in the US as it did in Japan. So it should be one of the discs from 2004. **EDIT** : Found downloads for all the demo discs, currently going to test every Japanese disc from 2004. So far I have confirmed its not the May or January 2004 Demo discs
