Nekketsu games and NES four score adapter.

So my goal is to be able to play 4 player Nekketsu games with the NES four score adapter.

I play these with a Everdrive N8 so I can use patched roms. I could also mod the Four Score itself but I think modding the game would be more simple though I cannot code at all.

Anyone interested in this? Those are the best 4 player games so I can't be alone wishing for that.

 

A bit more details,

Since most Nekketsu games were only released in japan they used the 4 player adapter rather than the four score which plugged into the expansion of the console. So the games expect different signals than what the four score would output. I've heard that "Nekketsu Koushin Kyoku" actually works with the four score adapter.

I don't know how I could go about and have the other Nekketsu Games work with the Four Score.

I need help on this.
