Celebrating #C64November with @retroslicegaming I posted a half-finished SID chip on Instagram. I got so much positive feedback I had to finish it. And here it is. Thank you all very much, for your kind words and support!
A friend told me it sounds like a bonus level from Flimbo's Quest (C64, 1990) and that is a *major* compliment! Hence the name; "Jimbo's Crest".
I would never compare my simple bleeps and bloops to legends like Johannes Bjerregaard and Reyn Ouwehand - but if other people want to do it, that's just fine! =)
