No.00034 Kold666 Developer Mar 2, 2008, 12:37	Also Kung fu Master use discrete sound for the drum. In general all m62 games have discrete circuit for some part of the music
No.00035 couriersud Developer Mar 2, 2008, 14:36	The schematics for the analog drums are known. However they are complex and do not fit directly into the discrete component network. They require at least some modelling from ground up.

In MAME that sound can be heard but is not bass sounding at all so it's no good just to raise the volume of that sound. Kid Niki uses that channel and so does Youjyunden, here is a recording i done from my Kid Niki PCB with the jumper in A and B position for comparison (in B-position it sounds like in MAME): http://www.ym2149.com/arcade/kidniki_j4_pcb_recordings.zip

No.00049 couriersud Developer Mar 4, 2008, 19:12	@Kold666: I have a copy of Kid-Niki schematics. They do contain the schematics for the analogue sound. These Schematics are very complex ... e.g. they do contain 6 or 8 inverter oscillators in parallel. In addition quite some mixing and feedback is present. This is a real challenge and very time consuming. This will most probably will take a lot of time until even tried.
