Describe the solution you'd like Add the ability to automatically find SDK C library functions to save time reverse engineering games.

Hi @Kuumba123

I tried to get this solution working some time ago. For those who read this, Ghidra has support for FIDB (Function ID dataset). Back in the day I tried to go through the different SDK functions (from the different leaked nintendo ds nitro SDKs) and generate FIDB function signatures for them, then you could import them and use them during analysis, but it was not perfect and I recall there were some collisions.

Probably someone could give it another try now in 2023 and report if the results are good, I think the FIDB codebase might have improved. I would happily bundle the files with a new release of the plugin, to easy reverse engineering.
