GBz80 to Items is an interactive online tool for converting Game Boy ASM into items for 8F (hex:5D) glitch item arbitrary code execution, or other arbitrary code execution methods that execute items as code such as the ws m (hex:63) glitch item in Pokémon Yellow.
It was created by glitcher and programmer ISSOtm. It is hosted on github as well as the French Pokémon glitch website PRAMA Initiative (for version 2.1 and the unfinished version 2.2).
This version is the latest (as of now) and the only one being maintained
This version was the first published, and is not maintained anymore.
It suffers from several bugs and it wasn't very ergonomic.
