Godmode9: Feature Request - Reverse-LZSS Decompress exefs/.code to code.bin

[shane-tw]

Adding this as an option to the context menu would be nice, as it'd mean not having to run

ctrtool -t lzss --lzssout=code.bin .code

in ctrtool afterwards.

Agreed, this would be a good addition.

Maybe this could be added in the form of a virtual file when mounting a NCCH-container? Code compression isn't a property of the .code contained in the exefs, rather it's enabled by a flag in the exheader of a NCCH. So instead of

romfs/
...
exefs/
|- .code
|- banner
`- icon

wouldn't it be possible to have something along the lines of

romfs/
...
exefs/
|- .code      (<- this is the uncompressed arm11 code)
|- .code.lzss
|- banner
`- icon

?

I'd like to contribute my interest into this as well. It would be useful for extracting DSP1 firmware via script without the need for special homebrew.

Just as a note - good sample code for decrypting the code is found here:

Thanks, @AnalogMan151

With that I would love if we had a way to simply dump dspfirm.cdc from one of the drives that already exist rather than manually using other script commands to find and pull dspfirm from home menu or mset.
