Why do the updates sometimes add SIDs that HVSC already had?
We often replace SIDs in HVSC with better versions. Reason for replacing SIDs could be (1) more sub-tunes (2) 100% rip (3) significantly smaller (4) merger of several SIDs. A “100% rip” includes SID tunes that are fully C64 compliant and where applicable have all subtunes. Thus, there is a chance that a new version of a tune could sound identical to the current version in HVSC. The new rip, however, has some internal changes that does in fact make it superior.
