This project is no longer under active development.
snap is a minimal 6502 assembler and crackle is a simple disk imaging utility. The main goal of this project is to create an assembler that is able to assemble the Prince of Persia for Apple II sources and create/update a disk image suitable for Apple II emulation. As such it will only support the subset of directives that are required by these sources. I don't know how useful it will be in general for other 6502 assembly language projects.
