You might find this tool useful.   It does BAS and XEX disassembly in a browser and can produce nice printable Basic listings in the classic font. Handy for quickly pulling apart a ATR or just spelunking through its contents. Disassembler is primitive but at least it has symbols. Atari Basic decompiler works with files that have missing variable name tables.   lmk if it is useful or if you have any feature requests. cheers   https://github.
