Seems I'm a bit late to the party, but I want to thank you BlueCrab for making this patcher. It's just what was needed. Should help a lot of people and that's a very good thing.
I do have a question though. Is it possible to have an sdiso version of this patch?
That depends on what you're asking. If you're asking if I will make a version that will patch the game as an ISO file on the SD card, no. I refuse to do that. This is much akin to patching the game on CD-R, another thing I will not do.
This whole patcher quite possibly overwrites data the SD card stuff needs anyway, so it might not be possible to make it work with that at all.
If you're asking if you can put this on a SD card and execute it in the normal way for SD card based homebrew, it should work fine. Everything's self-contained. I pretty much (except for final testing of it) always execute it over dcload. Granted, if there's some sort of exit back to the loader functionality in the SD card reading stuff (I've never used it, so I don't know myself), this may disable that (Just as it does for dcload).
