Zaccaria Pinball ASK to ZIP decrypter

Post by aluigi »

Just wrote a decrypter for the ASK archives used by Zaccaria Pinball:

Script:
http://aluigi.org/bms/zaccaria_pinball.bms



Technical info: fixed key, some shift operations on its 32bit fields, 64bit multiplication with constant and dynamic shifting. I had to use the runtime C compiler because bms is too slow for these operations.
