maketad

NOTE: This is an edited version of the official README.

Description

　maketad is a tool for generating TAD files (.tad) from the specified SRL file. TAD files are used to import applications into the system memory.

TAD files for TWL that are created with this tool can only be imported into TWL development kits. The TWL-SDK environment cannot be used to create TAD files that can run on retail TWL hardware.

Downloads

Standard maketad application. These create TAD files to be imported to development hardware through TwlNmenu. Output TADs will be encrypted with the Wii debug key (A1604A6A7123B529AE8BEC32C816FCAA).

Updater maketad application. These create TAD files to be used when compiling Twl SystemUpdater. Output TADs are encrypted with an unknown key and so they cannot be decrypted.

• maketad_updater-20050422.exe

Dependancies for maketad.

• cygcrypto-0.9.8.dll
• cyggcc_s-1.dll
• cygwin1.dll
• cygz.dll

Additional tools. These are not required, but are recommended for working with TAD files.

• split_tad_console-20090401.exe (usage: split_tad_console.exe TADFILE, where TADFILE is a TAD file to decrypt to SRL)

Using the Tool

Start Command

% maketad [OPTION]... SRLFILE [-o outputFile]

SRLFILE is the ROM file to import into NAND Flash. Specify an .srl file.

Use the -n option to output an SRL with an encapsulated TAD file rather than just a TAD file. Once the DS card to which this SRL has been written is inserted in the DS card slot of the TWL unit, you can import from the encapsulated TAD file by starting the TwlNmenu imported into system save memory.

With the -o option, the file name of the output file can be designated. If nothing is specified and the -n option is not specified, the title name saved in the SRL file with a TAD extension is created. If the -n option is specified, the title name saved in the SRL file with a TAD.SRL extension is created.

The -s option allows outputting a TAD with a reserved gamecode (eg. system titles). This feature is unlisted from the help menu.

The -h option displays simple instructions.

Return Values

Returns 0 when execution completes normally.
The following are possible reasons for the function to fail.

• The provided DLLs (see download section) were not found
• Nothing is specified with the -o option
• An unknown option was found
• Characters other than those from ASCII code 0x21 through 0x7e are included for the game code
• A code reserved by the system is being used in the game code (please use -s to bypass the error)
• The file is not of the type *.srl
• The SRL file cannot be opened or read
• An SRL file has not been specified
• A TAD file cannot be output
• The SRL filename is too long
