This is an experiment. xa65 is a 6502 cross assembler, running on Unix (and Unix-alikes), and producing 6502 and 65816 code. It comes complete with a set of tools. xa65 was originally authored by me, André Fachat, but currently and still xa65 is maintained by Cameron Kaiser at http://www.floodgap.com/retrotech/xa/ . Due to current time constraints Cameron can not do any updates, so I decided to create this repository to publish my (beta) version that implements a long outstanding feature: assembler listings... These are the directories: xa - contains the main source. The master branch is the stable version These are the current branches: master - stable branch, currently 2.3.5 listing - experimental branch that adds ca65 compatibility features and assembler listing
