.BLOCK EQUW ENTRY2-1 EQUW 512-LEN+BLOCK-ENDBLOCK+3Name: BLOCK [Show more] Type: Variable Category: Copy protection Summary: Addresses for the obfuscated jumps that use RTS not JMPContext: See this variable in context in the source code References: This variable is used as follows: * BEGIN% calls BLOCK * Elite loader (Part 4 of 6) calls BLOCK
These two addresses get pushed onto the stack in part 4. The first EQUW is the address of ENTRY2, while the second is the address of the first instruction in part 6, after it is pushed onto the stack. This entire section from BLOCK to ENDBLOCK gets copied into the stack at location &015E by part 4, so by the time we call the routine at the second EQUW address at the start, the entry point is on the stack at &0163. This means that the RTS instructions at the end of parts 4 and 5 jump to ENTRY2 and the start of part 6 respectively. See part 4 for details.
