 A very rough start to a Game Boy Advance emulator in Crystal Lang. The long-term goal is simply playability of popular titles. The name of the project come from the emudev discord, where "crab" was suggested for "Crystal Advanced Boy." Close enough.

 ## Installation
 
 At the moment, a `shards install` is all that's required.
 
 ## Usage
 
-This is not in a functional state. As arm instructions are being implemented, you can print the trace by compiling with `-Dtrace` or print logs by compiling with `-Dlog`. Next, simply provide the executable with the path to your rom.
