What is pokecrystal11.gbc?
Version 1.1 of Pokémon Crystal, which fixed some issues with the initial international release. make crystal11 defines _CRYSTAL11 so the assembly builds the changed version.
I can't build the ROM, make just prints an error!
Reread INSTALL.md carefully, and make sure you're following all its steps.
gcc: command not found
You need to install gcc. If you're using Cygwin, re-run its setup, and at "Select Packages", choose to install gcc-core.
"ERROR: UNION already defined"
Download the latest rgbds release. Versions earlier than 0.3.3 will not work.
"Segmentation fault" from rgbgfx
If you are using 64-bit Windows, download 64-bit Cygwin and 64-bit rgbds.
"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).
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 SECTIONs go in which banks. Try moving some code into a new section.
"Invalid file or object file version"
Run make clean to remove all the old o files, then re-run make.
How do I edit maps?
For asm scripts, read docs/map_event_scripts.md. For blk layouts, try Polished Map or crowdmap.
How do I write new features?
There are a number of special-purpose scripting languages, as described in docs. For more general features, you'll need to code directly in assembly language. See docs/assembly_programming.md. Some of the tutorials may also be helpful.
I need more help!
Try asking on IRC or Discord (see README.md).
