Hacking Wii U Menu info - sort WIP

[Ape8000]

The start of figuring out the Wii U Menu layout.
NO, THIS HAS NOTHING TO DO WITH INCREASING THE 300 LIMIT.

Menu Title IDs
USA 00050010-10040100 
EUR 00050010-10040200 
JPN

USA Wii U Menu layout file location: (8000000X where X is the User ID) 
storage_mlc\usr\save\00050010\10040100\user\8000000X\BaristaAccountSaveFile.dat

File Format:
0x000000 - 0x0012BF  NAND Title Entries (300 x 16 bytes)
0x0012C0 - 0x00257F  USB Title Entries  (300 x 16 bytes)
0x002587  Last ID Launched
0x0025A4 - 0x002963  ? Folder 0 ? NAND Title Entries (60 x 16 bytes)
0x002964 - 0x002D23  ? Folder 0 ? USB Title Entries  (60 x 16 bytes)
0x002D24 - 0x0030E3  Folder 1 NAND Title Entries (60 x 16 bytes)
0x0030E4 - 0x0030E3  Folder 1 USB Title Entries  (60 x 16 bytes)
0x0034A4 - 0x0034DB  Folder 1 Info (56 Bytes)
0x0034DC - 0x00389B  Folder 2 NAND Title Entries (60 x 16 bytes)
0x00389C - 0x003C5B  Folder 2 USB Title Entries  (60 x 16 bytes)
0x003C5C - 0x003C93  Folder 2 Info (56 Bytes)
0X003C94 .... FOLDERS 3 - 60 AS ABOVE

Title Entry Data Format:
Each entry is 16 bytes.
0x00 - 0x07  Title ID
0x0B  Type:
 0x01 = NAND
 0x02 = USB
 0X05 = Disc Launcher
 0X09 = vWii (Not Eshop vWii titles)
 0x10 = Folder (Bytes 0x00-0x06 = 0, 0x07 = Folder#)

If a 16 byte entry is set in NAND the corresponding entry in USB is blank (except for the type 0x02 at offset 0x0b) and vice-versa.

Folders are all in - 0x000000 - 0x0012BF NAND IDs.  USB entry would be blank (except for the type 0x02 at offset 0x0b)

Folder Entry Data Format:
0x00 - 0x21  Name (17 Unicode characters)
0x32  Color
 0x00 = Blue
 0x01 = Green
 0x02 = Yellow
 0x03 = Orange
 0x04 = Red
 0x05 = Pink
 0x06 = Purple
 0x07 = Grey

Barista huh? Well I guess if you RE the OS further you wont run out of coffee related jokes so thats nice. Seriously though, interesting to see that game limit is quite hardcoded in the offsets, I guess its nice to link people who wonder about it to this.

Wouldn't USB ID to be used to make Wii U formatted HDDs exchangeable between consoles without format?

Huh? Nothing to do with this topic of sorting the Wii U menu titles.

Oh, I see. USB IDs means the title ID of an item on USB.

Yeah, I chuckled when I saw the file name. They really went all in on the coffee theme.

I probably shouldn't sidetrack into this, but I do wonder if the menu could be hacked to support more. The format allows 300 in main menu, and 60 in each folder. Seems they imposed a total limit of 300 hundred for no reason. Though I have not looked at the other Batista files yet.

I don't imagine it will be as simple as finding the number 300 in the menu code and increasing it.

with all these coffee names, it makes me think what the internal names for the switch will be called

Looking at this format further and the other files, it may just be laziness on Nintendo's part that they limit the titles to 300. They just check if there are 300 titles, instead of checking if there are 300 on the main menu. They should have wrote the code to say the main menu slots are full, create a folder. Always leaving 1 space empty, until 60 folders are created. Then saying too many titles.

I imagine the Wii U Menu title could be patched to increase this (stop the too many titles error), but you would have to keep free icons on the main 300 for new titles to fill, then move them to folders. Otherwise it would most likely drastically crash. Who knows, maybe they have another check to stop a crash.

I'll always assume they limited it to 300 because no one in their right minds would ever install more than that, except for insane collectors and all-out pirates.
