Additional notes about legal stuff: modifying single-player is okay, but sharing or distributing modified assets could violate Rockstar's EULA.
Troubleshooting tips: if the frontend doesn't load after modifying, check for file errors, wrong compression levels, or file path issues. Maybe suggest using the log files from the game to identify errors.
Also, when repacking, some tools require you to replace the original x64f.rpf in the game directory. Maybe mention the exact location, like \Grand Theft Auto V\common.rpf\x64f.rpf, so the user knows where to place the modified file.
