update vice past r37819

[kiwanowski]

hello, is it possible to update vice past r37819? I plan to use bmc64 for music composing but for a really long time vice had a filter saturation bug for 8580. It was reported here - https://sourceforge.net/p/vice-emu/bugs/909/ and fixed in r37819

Below is a quick comparison of vice 2.4, vice 3.x before the fix, and vice after the fix:

See attached diff that provides the 8580 filter fixes from r37819 (and earlier) made against current bmc64 source.

and the kernel binaries for anyone who can't compile:

Feedback welcomed!

(Congrats! Pretty sure this was the last 'big' thing from upstream VICE that Randy felt was missing!)

Cool. Thanks for putting that together. I should really dedicate some time to putting out another update. I've been obsessed with my latest project though and never seem to find the time.

The below-attached ZIP should now work on all systems (including Pi Zero) and includes paddle support as recently added, the 8580 filter fixes, and the Xbox 360 gamepad button fix.
