I may want to see command-line alternatives to some GUI software. What I want is software that is less stupid. Allow use together with other software. Some things may be split into separate programs which can then be piped together, e.g. if you have a NSF music player then they might be: - Execute the 6502 code in the NSF file and write the register writes and delays to stdout. - Read the register writes and delays from stdin and use that to generate an audio signal to stdout. - Play the audio on the speaker, or else encoding it as Opus or recording it on a CD or whatever, can be the third one, which would also be able to apply filters and global volume control and stuff if you want to do.
