Credit to Fancy247 for the original hacking and design of the Gameboy Color players and Triclon for the work to figure out how to patch them into the game!
This took tons of time and effort looking through the ROM, but I was finally able to figure out how to make it so every player and course is permanently unlocked directly within the game ROM itself. This is something I felt was necessary and appeared to have not been worked out yet by anybody.
Something that had always bugged me is that to have every player and course you had to have a legitimate game cartridge painstakingly unlocked by playing through the game, use emulators with Gameshark/RAM edits, have an Everdrive with Gameshark codes, or do other inconvenient things. With this Patch/ROM hack, it's all set and ready to go. As you can see me demo you have every player and course unlocked before you even tee off once. This allows for a data reset without losing the players or courses if you wanted to wipe the gameplay memory clean. Also, something the game previously didn't allow was to have multiple players select the Gameboy Color characters and that limitation has been removed. This was likely due to Nintendo trying to prevent a team of 4 people racking up a ton of experience points in one round with a GBC character but I can't confirm their intent 100%. With my build, you can select all 4 players to be GBC characters now!
To play this ROM, you need to use a patch program to patch a stock unmodified Mario Golf 64 ROM you have provided yourself. The program takes the IPS file and make the changes in the game. There is plenty of info out there how to do this. I use Lunar IPS to make and test the patches.
Here is a link to the game ROM I use in the video, where the Gameboy Color characters have been added thanks to Fancy 247's ROM hack, implemented into the game by Triclon and his Gameshark Code Injector.

Here is a link to a patch where only the original roster of 14 players are included. I did this just to be thorough and have a version of the stock game where everything is unlocked.

I am hoping this hack will become the standard Mario Golf 64 ROM file to be shared and distributed for everyone to enjoy. Cheers!
