Security code

Pointed from $182 (in the 68k program header). This pointer must be even !

The System ROM compares this code word per word with its internal copy (which is located at $C146CA for SP-E, and $C146A2 for SP-E v2) as part of the cartridge detection routine.

There is some jumps to the security code inside the system ROM but it seems to never be called (at least in SP-E v2).
