Ok, so I finally got curious and took apart the older EA (fat track) loader. I even ended up writing a disassembler for the P-code that it uses. I know it's not earthshattering, but the EA protection section is a bit thin on details. If someone would like me to write up an article on the loader and the P-code, I'd be happy to. |

E-mail it to me at peter@c64preservation.com and I'll be happy to put it up on the site. |

I remember trying to crack Hard Hat Mack and another EA game (One on One?) with a friend. In the end, we figured out that the loader wasn't "protected" and we inserted a BRK where the JMP command was to run the program. After that, the file was just 10 SYS 2063 (or something like that). We saved it and had a cracked copy. Some of the later games like Archon didn't work that way though. |
