While reading GBATEK, I found this:
Well I could just install Sudoku hax but...
So we can use another title's tmd to have another copy of 4 swords on that tmd's path, but it will be useless if it reads the same path for save data, have anyone tested this?The Launcher does verify the .tmd's RSA signature, and uses the Title/Content IDs to create the path/filename for the .app file. The Version, Size, SHA1 entries are not verified, so one could use any .tmd version with any .app version (when renaming the .app to match the .tmd's Content ID, but that'd be a messy solution, and it's better to use the correct .tmd per .app).
