Here will appear two on-line tools to help with coding for the Amiga (currently in Alpha), and an Amiga assembler which I use to code all my stuff - it will be released as soon as I finish the code folding feature and add some 680x0 compatibility for the debugger.
To try the command line tools I've made for the Amiga so far, go to Helpers under Downloads. A light-weight command line file viewer is coming.
