The 2MB Run `make clean` to remove all the old `o` files, then re-run `make`. +### "Syntax error" + +You've made a mistake while writing some of the code. Re-read the modifications you've made to the file it complains about and try to compare them with other code. + +If you're not using the latest version of [**rgbds**](https://github.com/rednex/rgbds/releases), update this as well. Don't forget to `make clean` afterwards. + ## How do I edit maps? For `asm` scripts, read [docs/map_event_scripts.md](docs/map_event_scripts.md). For `blk` layouts, try [Polished Map][polished-map] or [crowdmap][crowdmap]. +## How do I edit the colors of an image? + +Most `.png` images are paletted PNGs. You can edit these with any program that supports creating PNGs with palette information. These palettes should consist of exactly 4 colors. Additionally, for Pokémon images, the first color should be white, and the last black. Tools such as Paint and [GIMP](https://www.gimp.org/) will do the right job, while other tools such as Photoshop might mess it up and output palettes of 255 colors even though only using 4. You may try using tools like [GraphicsGale](https://graphicsgale.com/us/) or [IrfanView](https://www.irfanview.com/) to fix this, or sometimes resaving the image in Paint seems to help. + +Some image `.png` files are greyscale. This indicates that even though these images do have proper colors in-game, they're shared with something else, and as such changing them will affect other things as well. Don't try opening the `.2bpp` files, these only contain the image data as well, not the palettes. + +It really depends on what image you're trying to change the colors of, where these colors are specified. Try looking for related files or `.pal` files. + + ## How do I write new features? There are a number of special-purpose scripting languages, as described in [docs](docs/). For more general features, you'll need to code directly in assembly language. See [docs/assembly_programming.md](docs/assembly_programming.md).
