Which SIDs are usable by Shredz64

While Shredz64 has the ability to use SIDs not originally included with the game, there are a few limitations. One, the SID must load into Bank 0, or the first 16K of memory - and above the $0909 (about the first 2K). So the SID must load within $0909 - $4000. Additionally, the SID must have a callable player - if the play address is $0000, it will not work. Lastly, the SID must not use PlaySID samples, which cannot be played back on an original C64. Shredz64 will take both NTSC and PAL sids though.
