Also there's really no need to implement letting P2 use the partner-change menu since you can just remap the buttons to the P2 controller in your emulator (could be nice for Wii WADs).
Not all of them are necessary anylonger now that we have angrylion and rdp dynarec in retroarch, like the fix for PJ64 2.1. I know he's most likely tied up with other projects, but it would be great to see some of the planned features get implemented. *Fix flying partners being able to fly through walls after performing a special action *Match camera zoom to Mario/Partner distance apart *Allow Mario's partner to interact with various game objects *Jump from a single A-button press rather than a rapid-fire *Player two can control Mario's partner while in battle *Player two can control Mario's partner in the overworld *Readme more helpful regarding online play, removed buggy graphics plugin from included emulator *Fixed bug where ending a battle as player two does not restore control to player one *Player two can perform the partner's c-down action in the overworld *Fixed graphical errors in PJ64 by disabling checksum *Either player can hold R to lock the camera onto themselves If you are using Project 64 2.1 or later, the CPU mode needs to be set to 'Interpreter'.
