"Market" for old macs?

While it's not the sort of game you're talking about, I recall discovering some of the elaborate copy-protection "defense in depth" in the Tempest ROMs. I've been on-and-off (rather "off" for a while now, I fear) working on a fully commented disassembly of the Tempest ROMs. It's only 24K of ROM, including all the vector-generator tables...and there are at least two pieces of code that try to ensure the game breaks mysteriously if you change or dike out the copyright notice on screen. (Indeed, one of them is buggy and thinks valid copies are invalid; it's responsible for the easter eggs you can find described for Tempest - certain values in the low two digits of the score at certain times can produce weird and wonderful effects. This is a misfire of copyright-anti-dikeout stuff.) Not much good unless the game is inherently "online", 'cause it means the game can't be played unless it can connect to the mothership. Still defeatable by use of emulators or ICE tools, though; while they can do things like PK-encrypt the game's code, the code must at some time exist in executable form, and can be copied then. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
