Dit it happen in previous versions ? because absolutely nothing has changed regarding memory card support since the last official release.

Fixed in r435.

For further reference, it was due to 2 things:

(1) memory card encryption was disabled by writing to gamecube EXI base address (Wii hardware uses a different address) (2) the return status of the CARD\_GetSectorSize function was not checked which could lead to infinite loop in case of error.

k,thanx. sorry 'bout the duplicate. i used the latest libogc with 3rd party classic controller mod.thats probably the source of my issue. i have an sd card. i just use the memcard to compensate for the lack of saveslots.

For the record, I got issues too, even with the latest libogc from SVN. It was when trying to load a savestate which did not exist: instead of giving me an error saying the file was not found, it hanged somewhere in the code, probably trying to read a nun-existent file.

The problem is that there is nothing in my code that can explain the infinite loop and as I said, there haven't been any changes since the last official release, I only secured some parts I reviewed in the last revisions. More over, the issue is not constant and I successfully saved/loaded state files on the memory card.

The reason is probably that Wii memory card support in libogc is quite unstable or have been modified: I know they commited some fixes lastly, it might have introduced some issues while fixing others, I really don't know. It might also be relate dto memory card types (official or not, sector size, format, free space, etc).
