This is a cycle-based version of a C64 music playing library
developed by Simon White. This library provides no internal
SID emulation. Instead a means to drive any external SID hardware or
emulation has been provided using the SID Builder Classes.
A ReSID Builder Class using a modified version of ReSID 0.13
is included in this package. Alternative/updated classes can be
obtained from the SIDPlay2 homepage.
