still a WIP however hopefully with some more work I can get this into a workable state...

(Amazingly Newer!) Update:

so now ball extraction works! still need to cut the images up but that should be simple

(also move graphics are basically done except for ICE_CHUNK it is a weird image... and I don't know how I am going to cut it up... but everything else is working! that makes it sound like ICE_CHUNK doesn't work... which it does it just doesn't get nicely cut up)

(Even Newer!) Update:

moves now work... kinda... still working on getting it all the way done but it mostly works!

(Newer!) Update:

still a WIP :p but erm you can extract more graphics!

Update:

so the project is semi-usable now you can download it as a npm package via:

npm install silphscope

(or pnpm install silphscope if you like pnpm like me ;] )

general use is something like this:

import fs from "fs";
import { renderAllGraphics } from "silphscope"; // this is cool...

const rom = fs.readFileSync("pokefirered.gba"); // replace with path to your own firered rom
await renderAllGraphics(rom, {
    outputMonDir: "./Assets/monImages", // must I explain?
    outputIconDir: "./Assets/Icons", // same thing here :p
    outputTrainerDir: "./Assets/Trainers", // ...
    outputMoveDir: "./Assets/Moves",
    sortUnusedMoves: true, // just sorts the unused moves into a sub-directory
    outputBallDir: "./Assets/Balls"
});

Of course though the above is for extracting all graphics (which is kinda a lie... In reality it only extracts mon images, item icons, trainer images, move images, and ball images... but like I said this is a WIP :p so wait a bit please!).

But if you want say just the mon images or item icons refer below:

mon images extraction:

import fs from "fs";
import { renderAllMons } from "silphscope"; // never gets old :p

const rom = fs.readFileSync("pokefirered.gba")// once again replace with the path to your own firered rom
await renderAllMons(rom, {
    outputDir: "./Assets/monImages", // do I actually have to explain?
    icon: true, // set to false if you don't want icons I guess...
    footprint: true, // same as the above...
});

item icon extraction:

import fs from "fs";
import { renderAllIcons } from "silphscope" // :D

const rom = fs.readFileSync("pokefirered.gba")// find your own rom and so on :l
await renderAllIcons(rom, {
    outputDir: "./Assets/Icons" // no comment (wait... that was a comment :p)
});

trainer image extraction:

import fs from "fs";
import { renderAllTrainers } from "silphscope" // :O

const rom = fs.readFileSync("pokefirered.gba") // stuff stuff stuff
await renderAllTrainers(rom, {
    outputDir: "./Assets/trainers", // more stuff
    trainerBackPics: true, // renders the like 8 trainer back pics
})

move image extraction:

import fs from "fs";
import { renderAllMoves } from "silphscope" // :O

const rom = fs.readFileSync("pokefirered.gba") // stuff stuff stuff (more stuff!)
await renderAllMoves(rom, {
    outputDir: "./Assets/trainers", // (incredibly) more stuff
    renderMasterImage: true, // kinda forgot about this... basically it renders a uncut image of the move anim if you like
    sortUnused: true, // sorts unused moves into a sub-directory
})

ball image extraction:

import fs from "fs";
import { renderAllBalls } from "silphscope" // o-O

const rom = fs.readFileSync("./path/to/your/rom.gba") // the file path explains :/
await renderAllBalls(rom, {
    outputDir: "./Assets/Balls",
    ballParticles: true, // set to false if you don't want the ball particles :p
})
