i still haven't made real chiptune. my music sounds similar, but it's not really using pure waves like these. i use hybrid synths that emulate some of this but with a reverb/muffled/wet flair, usually. chiptune has an interestingly pleasing dry-cut feel while i try to make mine more like liquid soap.
i have no hope, i hate this game, i'm wasting my time, this only fuels my self-destructive competitive habits, this thread makes me into a miserable fool,
