SDHC support for non-SDHC games?

What would need to be changed to accompolish SDHC support in a non-SDHC game?

I think all that's needed is for it to be re-compiled. This can be done by anyone if the app is open source. otherwise, the author of the app needs to.

Yes, just recompiling under the latest libogc will add sdhc support, but some apps wont compile under latest libogc without modification.

Yes I know all of that, but I was reffering to an actual wii game not a homebrew game. Sorry for the unclearity.

then you need to get in touch with the developer :-)

There is no way to add sdhc support to an already existing game, without the publisher releasing a new version of the game.

Wait, so games like Brawl cant write (save) to SDHC cards?

Do you know where the SDHC code is located. Is it in the .dol or is it handled by an IOS or where is it?

There's always a way. If for example the SDHC code is located in the .dol, a very skilled person could make ocarina cheat codes to modify the .dol so it supports SDHC (to my understanding).

@Arikado: I have no idea, I'm on 3.2, so I don't know. I would be really strange, though, if SDHC saving is only available for newer games.

true. Either it goes through IOS (Whch I am 90% certain it does) and would have SDHC with 4.0+. Otherwise an Ocarina code (a very long one) would be able to add SDHC.

If it goes through IOS. Why hasn't Nintendo just updated that IOS to make it SDHC supportive?

edit: maybe I misunderstood you. Do games have SDHC compability if you have system menu 4.0+?

I'm almost certain bushing or someone like that said games made before SDHC being added to System Menu weren't compatible, and never would be. But I could be wrong. As of now, I'm pretty sure games such as Brawl cannot use SDHC cards for saving stages and screenshots.

I can say that games do not work with SDHC on 4.1

Ok!

Then, the SDHC code must be handled by the .dol or am I wrong?

Yup. Hence how The HBC added SDHC

Yes, SDHC code must be compiled into game/app, hence homebrew compiled under latest libogc has SDHC support. However, it'd probably be VERY hard to add SDHC support with an Ocarina code. My advice would be this: get the .dol of a game with SDHC support, and one of a game with only SD support. Disassemble both with IDA Pro (You'll have to pay for it to get the version which works with .dol files). Find the sections in both which handle SD loading, then somehow write an Ocarina code to patch the SD game with the code from the SDHC supporting game. But I don't know how you'd recongnize which part does SD loading, or how you'd write the Ocarina code. It'd probably be a long process, which would require done for every game you want to add SDHC support to.

The code would probably be so long that Ocarina would choke on it. :-)

Yeah, quite possibly.

Why? Which are the SD functions? Save file? Open file? What more? If the functions would be declared inline it shouldn't be that hard to make the codes if you just knew where the funcitons are located or am I missing something here?

Well, SDHC is managed in a completely different way to SD. Look it up on Wikipedia. It is a lot more Software based than Hardware based.

I've look it up. What I mean is, once you know where the SD functions are, they shouldn't be too hard to rewrite to SDHC functions even though they are quite complicated since the they have already been written by others.
