    I just adquired a sexy 8GB SDHC SanDisk, (class 2 thought), I find out that it can run very old apps that doesn't have SDHC support!! (?)
    Kinda strange, I wonder if it something to do with the HBC itself. Not sure.

    It run perfectly a old ass WiiMote demo app, and Hermes Wiireader, textED, DMP, among others...
    Cool beans, uh =P

    I'm not sure, wiireader is very old, the same with Wiimote Demo, I highly doubt they run under 249, not even designed with 249 in mind.

    HBC channel loads the apps, and it supports SDHC. After the apps are launched most of them don't even access the SD card.

    Thought of that, too. Or does WiiMote demo write debug output to SD?

    If they don't reload IOS, they're running under HBC's IOS, likely IOS61. IOS61 is SDHC capable. It's the IOS that matters, not the loader.

    Some don't access SD after loading, but DMP certainly does to get the music. Does anyone know if DMP reloads IOS? I'll bet it doesn't.

    At least in case of the HBC this is incorrect. The app get's always loaded on IOS36, even if __IOS_LoadStartupIOS() is nulled.

    Fail. SD and SDHC use different addressing modes, even if the IOS supports SDHC the app must support it too. Otherwise we could run old games (SSBB, GHWT, RB2) under the new IOSes and they would magically support SDHC.
