    For context, I want to find a way to have my node.js program "poll" game data from a running Fire Red emulation in order to get information related to the player's progress. Like it would be able to detect which badges, and which key items the player has received.

    I'm very new to ROM hacking, so I'm just looking for some help / someone to point me in the right direction. Thanks!
     
    1. Find a way to read the memory of the emulator process with the language of your choice(maybe this).
    2. Find where in memory the emulator of your choice stores the emulated console's ram.
    3. Find where in that ram the data you want to access is.
    (4. Profit)

    EDIT: I overlooked an easier way to do this: use an emulator that supports lua scripting and dump the desired data with a lua script.
