New SID 8580 implementation for the C64 core

Postby Chris23235 » Wed Jul 11, 2018 6:41 pm

Rayne has written a new 8580 implementation for the C64 core, I think it sounds very good.

I tested it with Turbo Out Run intro, but it sounds like old core.
Even with the following pokes:

POKE 54297,255 and POKE 54298,255

Which are the games where this new SID update make a difference ?

I think the startup sound in Giana Sisters sounded more like I remember it and the percussion in the ingame music sounded a little bit less tinny than on the old core.

Ask him if he is willing to share the SID sources

Giana Sisters intro sound is designed for old 6581 SID.

Try it on a real old C64 with SID 6581R4 or SID 6581R4AR

Thanks Chris for sharing such nice news!
Special thanks for Rayne, Gehstock, Sorgelig and every developer who still polishes FPGA-code for reimplementing of legendary C64 for rest of us!

I've just checked collection of modern tracks from LMan and psych8580 for 8580, recent demos and they sound fairy well to be truth at all(especially in comparison with youtube records from real C64).
MUS1K from 4-Mat of Ate Bit, Orb sounds respectively good too. Sounds Of The Amiga music disks are playing addictively now.
Metamorphosis, Legacy and Melonade by Dane are equally fantastic to sound perception from real C64. Valentine? What about Black Burning Heart? Check'em by yourself :)
Yeah, some LMan's tracks in PRGs output white hiss only, it needs clarification. Maybe they need some configurations with pokes before run, maybe someone will spot the light on this hiss from core side.
Just few strokes about LMan's "8580 only"&technically sly tracks on this version of core:
Jeroen Tel and LMan - 11 Heaven = OK
Jeroen Tel and LMan - Skypeople = OK
LMan - 808 Love = OK
LMan - Age We Aceeed = OK
LMan - Boombox Alley = OK
LMan - Confusion 2015 Remix (cover from Blade movie) = OK
LMan - Could Be Cool = OK
LMan - Hell Yeah = OK
LMan - Hi Fi Sky = HISS, brilliant track on real C64 too
LMan - Mellowhouse = OK
LMan - Milk & House = OK
LMan - MONOFAIL = OK
LMan - My Club House = OK
LMan - Rastaline Dub = HISS
LMan - Robot Sensuality = HISS, brilliant track on real C64 too
LMan - Vortex = HISS, brilliant track on real C64
Rapture and LMan - Giana Sisters DS = HISS, brilliant track on real C64 too
It would be great if developers take a look to these tracks with HISS. By the way, OK == FAB.

Anyway it's huge step close to authentic sound of real C64. Just remember where C64 core was few years ago.
Well done :D

P.S. Thanks. Now I know how SUMMER'18 sounds for me: coreSIDent with 8-bit !
Make you favor, take a break and you'll find out how great & beautiful scene on C64 is.

Confirm, there are good improvements on sound in Giana Sisters.
