IPS patch for VC Crystal vs. original Crystal?

I remember there were patch files floating around for VC RGBY and GS when those were released, which is how we found out about some of the subtler changes like the HUD not disappearing for GS, or the Pikachu's Beach House posters not working correctly in Y. Do we have any similar file for Crystal?

(Side note: I'm surprised no changes have been reported about Japanese Crystal's Battle Tower or PCC. Now that language alone gets a Battle Tower that's locked forever and a building that's 60% locked forever.)

Are there still links to patches for Y/G/S?

I downloaded but it wouldn't let me open the file correctly. Is it possible to post here what the patches are?

Just open the .patch files in your favourite text editor.

Thanks! Looks like this includes all 7 Gold languages, all 7 Silver languages, and all 6 Crystal languages. Is there a mirror for Gen I as well? (The link in the original thread here is broken.)

Which patch is the one that enables the GS Ball event? [BiographySave_ret] is the only patch that appears in Crystal but not G/S, but the name doesn't look related to the GS Ball.

That patch has patch type 60 (IIRC), and is actually implemented in the VC itself. Talk about a way to be lazy fucks, Game Freak. (They unloaded their work onto Nintendo)

(This is why I hate Game Freak and their games, btw.)

So… the actual GBC file is not edited?

I have the Red/Blue/Yellow and Gold/Silver, Crystal (old prerelease patch) at my Google Sites here:

Have just added Wack0's release Crystal patch copy.

Thanks for the resource!
If these changes are applied to a GBC rom, would it be identical to the VC release? In other words, do any of the changes rely on VC itself? (Wireless communication is an example, I suppose.)

You're welcome! :)

I don't know for sure but I think mainly yes, except for the wireless linking features (but I'm unsure how they work on a technical basis other than two 3DS pause and link wireless from invite/accept on the Touch Screen). Another technicality is that unknown opcodes were ignored on Red/Blue/Yellow VC so probably are ignored here as well.

Having a look through Wack0's files I can't seem to locate what activates the Celebi event though. Hmm.
I got confused for a moment because some of the files are from Gold/Silver (possibly the AAU ones based on GameFAQs serial code data).
Wack0, are these the right files?

Are there any chances that the GBC file is actually modified to unlock the Celebi event so that it's not in the patches?

The Celebi thing is in the patches. It's just a very specific patch type that has been made specifically for this game, for the VC.

Right, the emulator hooks a function return and modifies SRAM itself (ie, it's done by ARM11 code, not interpreted LR35902 code).

I would like to inject a gbc rom of the German version of Pokemon Crystal (Pokemon Kristall Edition) into a VC cia for 3ds with one of these patches.

However, which of these patches do I have to use for my german crystal rom? There are 18 different patches and I dont know, how to determine, which is the correct one.
