The HotDog hack:
When the HotDog prototype was discovered, some people aquiered actually the copyright on it. For that reason, a new title picture had to be included in the ROM before it was sold to public. I did this with the most minimalistic hack i could think about. I added the new picture to the end of the ROM and “just” changed the directory entry in the encryped loader. As the encrypted loaded ignores the actual directory entry, it is still the same. This means, if you run the encryption utlity on the ROM or replace the loader by another (hacked) one, you will have the original title picture back.
