|  Re: SD2IEC SID Player
I just want to add a fact: there is an alternative version of SID files on the net: a C64 compatible version. Those are real PRG files (directly executable on C64).
"Real" SID files - as Epy wrote - are data files which actually contains the player code (in most of the cases) but they can't be played without a specific player.
By the way loading SEQ files is as simple as loading a PRG, you just have to add ,S after the filename (and of course supply a load address where you want to load the data).
I think Epy's player uses this method to load SID files too (of course without the file type specification - which is by ignored by my player too but will include it in the next release  ). My player uses CHRIN and loads SID files byte-by-byte. I did some performance tests with my player (I can't remember which SID was the subject):
- 1551: 15 seconds
- stock 1541: 25 seconds
- JiffyDOS equipped 1541 (and plus/4): 12 seconds.
Epy's player seems to use JiffyDOS fast loader and its much faster.
