No.23160 125scratch Tester Mar 26, 2025, 17:27	Thought I'd send an original hardware reference I recorded myself. https://files.catbox.moe/3ulixl.wav
No.24168 125scratch Tester 1 day ago	I tested a build with the new fix, and I have to say the duration of the sound is pretty much perfect, but the tone itself is still a bit too loud. On the original hardware it sounds more "smooth".
No.24169 125scratch Tester 1 day ago	When analyzing the sound effect slowed down 0.25x, it seems like the original hardware only has the relatively lower-pitched "slide up" component, and doesn't contain the scratchy higher-pitched part, though the skid sound still has that.
No.24170 hap Developer 1 day ago	Ok I'll reopen the bugreport. And to make it sound clearer, try this in nl_mario.cpp: (still not 100% correct, and much slower to emulate) PARAM(Solver.DYNAMIC_TS, 1) PARAM(Solver.DYNAMIC_MIN_TIMESTEP, 1e-6) instead of: PARAM(Solver.DYNAMIC_LTE, 5e-2) PARAM(Solver.DYNAMIC_TS, 0)
No.24173 hap Developer 18 hours ago	I enabled DYNAMIC_TS and left the other param alone here: https://github.com/mamedev/mame/commit/87e09a4cc840a0cc9c4499ad697e201854728f36 Sound is clearer, netlist emulation is slower but not excessive. Good enough to resolve bug report?
No.24182 125scratch Tester 7 hours ago	Hmm, I'd say the high pitched part of the sound is still too loud, but this is still a lot more accurate than how it was before you made any of these changes. The report can be resolved if you're sure there's nothing that can be done to make it more accurate. I understand that these analog sound effects are difficult to emulate.
No.24183 hap Developer 7 hours ago	The 1st video in the above list has the clearest audio, I think the 'wip wip wip' sounds about as loud as MAME? It's less clear on the other videos.
No.24184 125scratch Tester 7 hours ago	Fair enough, maybe it's accurate. It just sounds a bit much to me personally. It might vary a bit between boards.
No.24185 125scratch Tester 7 hours ago	I found a direct PCB capture reference:
