N64 Mouse Input Hack "Need advice"

[mark2001]

Hey, I'm working on an n64 jet force Gemini mouse input hack
and I know that it uses the X-axis and Y-axis to move the player
I found the addresses in memory but would have to look up them again
in my disassembler to say what they are.

Is it a good method to use the write to memory function in c++
and just create an if statement to store the new controls.
Or is there an easier method or am I doing it all wrong?
what's your thoughts and what code example can you provide
on how to achieve this.
help would be greatly appreciated.
I can also properly use SDL for proper mouse control support in my code.
