Earlier versions will not work. + +## Can't build ROM; "Segmentation fault" from `rgbgfx` + +If you are using 64-bit Windows, download [**64-bit Cygwin**](cygwin) and [**64-bit rgbds**](rgbds). + +## Can't build ROM; "Section is too big" or "Unable to place section in bank" + +If you have not changed any of the asm, make sure you have the latest version of pokecrystal and the correct version of rgbds (see [INSTALL.md](INSTALL.md)). + +If you added or changed any code, it has to fit in the **memory banks**. The 2MB ROM is divided into 128 banks of 4KB each, numbered $00 to $7F. The linkerscript **pokecrystal.link** lists which **`SECTION`**s go in which banks. Try moving some code into a new section. + +## How do I edit maps? + +For `asm` scripts, read [docs/map_scripts.md](docs/map_scripts.md). For `blk` layouts, try [crowdmap](crowdmap) or [Polished Map](polished-map). + +## I need more help! + +Try asking on IRC or Discord (see [README.md](README.md)). + +[cygwin]: https://cygwin.com/install.html +[rgbds]: https://github.com/rednex/rgbds/releases +[crowdmap]: https://github.com/yenatch/crowdmap/ +[polished-map]: https://github.com/roukaour/polished-map |
