The SID file header v1
======================

The detailed structure of the SID header looks like the following. Header
offsets are in hexadecimal notation. Other integer values are decimal unless
explicitly marked otherwise. Any stored integer values are in big-endian
format:

+00    magicID: 'PSID' or 'RSID'

This is a four byte long ASCII character string containing the value
0x50534944 or 0x52534944. 'RSID' (Real SID) denotes that the file strictly
requires a true Commodore-64 environment to run properly. 'PSID' files will
generally run trouble-free on older PlaySID and libsidplay1 based emulators,
