Hi! I'm back with a question or two after making a good bit of progress on Dolphin's WIA implementation. As you know, wia_exception_t is used to replace 20 bytes of automatically calculated hash data with other data. This made me wonder: How does wit handle exceptions in the padding data between hashes, since some of this padding data is 32 bytes instead of 20 bytes? And the answer seems to be that wit actually doesn't preserve this padding data when converting to WIA. I tested this by changing …

Zitat von Wiimm: „I believe, that IOS will read the blocks usually in ascent order (e.g. read complete files). “ The game can ask IOS to read only a part of a file. (IOS will align the access to 32 KiB blocks since this is necessary for checking the hashes and decrypting the data, but not more than that.) This is crucial for very large files that can't fit into memory all at once, such as pre-rendered video. But yes, if the game does request several blocks at once, the blocks will be read in asc…

Thanks for letting me know your position on this. I will probably go ahead with the new format I was planning, then. I'm not aware of any reason why IOS would need to read the full 2 MiB for checking whether the hashes are correct rather than just 32 KiB. First you pick the correct H3 hash and compare it to the hash of the stored H2 list, then you pick the right H2 hash and compare it to the hash of the stored H1 list, and then you pick the right H1 hash and compare it to the hash of the stored …

Hi! I originally PMed this to you (Wiimm) on GBAtemp, but it seems like you aren't active over there anymore, so I figured I would also post this here. If you've already read this, apologies for bothering you about it again. -------------------------------------------------------------------------------- I'm currently working on implementing WIA support in Dolphin. (The pull request is at github.com/dolphin-emu/dolphin/pull/8538 if you're interested.) I think WIA would be a good addition to Dolp…
