Retro Achievement support through rCheevos

[ZaneDragonBorn]

Emulators such as RetroArch, melonds, and more feature support for Retro Achievements and it makes it really hard to pick this one over the rest due to this missing feature. It makes playing these games a whole lot more rewarding and I was hoping for support.

After digging for information, I've learned that people use rcheevos to add support. Though people did note that you have to implement the "network and UI layers" for it. Additionally RAInterface will outline things to consider when adding support. Though you can't use this as it requires RAIntegrate which is Windows only.

I may try my hand at adding support myself but I am fairly new to coding so currently gonna have find some time to break things on my end.
