Noah98 Posted September 21, 2013 Share Posted September 21, 2013 I just picked up the game Moondust for the C64 (this games is insane) and I can't get any sound. I have 10 other cartridges that all play fine with sound, so I don't think it's the computer. I've cleaned the contacts on the game and they appear fine too. Am I missing something with this crazy game? Quote Link to comment Share on other sites More sharing options...

carlsson Posted September 23, 2013 Share Posted September 23, 2013 i just tried an "emulator version" of the game and can confirm it has spooky sounds, almost like random music. A lot of it sounds like combined waveforms, whether your SID chip would have some issue in reproducing those. I didn't study the code to see if the game initializes in an unusual way, or perhaps addresses a shadow memory location. The SID chip normally resides at $D400 but I believe it can be accessed at multiple addresses as long as no other hardware is added to the memory map. If that is the case, perhaps you have a partly bad PLA? Is this a breadbox C64, a newer C64C or another model? I could probably supply you with a few dozen "unusual" POKEs to try in Basic to see if you get sounds from those. Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted September 24, 2013 Share Posted September 24, 2013 I'd forgotten all about this trippy game Quote Link to comment Share on other sites More sharing options...
evietron Posted January 18, 2019 Share Posted January 18, 2019 (edited) There is a bug in the game which causes it to not have sound in certain cases on NTSC machines. My guess is that if you pop it up on a first revision C64 with 5 pin video that it will work properly. I just picked up the game Moondust for the C64 (this games is insane) and I can't get any sound.

I thought I had a bad cart or something since I never noticed any SID issues with any other games. I'll have to see if I can track down a machine it's actually compatible with.

Noah98 Posted February 25, 2019 Author Share Posted February 25, 2019 Thanks for the info! I was convinced that either my cart or the system was defective! Much appreciated ? Quote Link to comment Share on other sites More sharing options...
