Convert txt codesets to gct for Wii on Mac OS or Linux

readme.md

Instructions & Troubleshooting

• If you're on Mac and prefer double clicking rather than full terminal, rename it to txt2gct.command so you can double click to execute it.
• make sure the .txt is next to the .sh/.command (or you know how to modify paths)
• chmod 777 txt2gct.sh (or txt2gct.command if you named it that)
• if you DID NOT use a premade .txt from a different build / if you made the txt from scratch, comment or remove line 23 and rename hax.txt to $file on line 26. so if your .txt was from a custom build (which likely used codemgr) then you don't need to do anything.
• haven't tested on files with spaces in name, so if possible rename the .txt without spaces.
