Game Problem: Unlocking all characters on Mario Tennis GBC on an emulator?

Hi everyone,

I've been trying for ages to find out a way to unlock all the characters & courts in Mario Tennis for the Gameboy Color.

The problem I'm having is that a few characters can only be unlocked via transfer pak. I see it's possible to unlock N64 content using project 64, but I'm struggling to find a way to unlock the content on the GBC side. Would anybody know how I could do this? Does anybody have any codes or a save file that I could use with the Lameboy emulator?

Thanks for your time!

This has now been solved. PJ64 transfers work both ways and unlock content on the GBA game too!
