I'm affraid I'm not tech-skilled enough to understand your answer!
What's decrunching? Is it related to memory?
No I don't have "compacks"... I don't THINK so to be precise... I had some cover-disks with two or three pd games on each but that's all.
Most of my disks where original commercial games, and a few cracks.
[edit : oh and I remember I had a game that displayed "decrunching - please wait" before the title! I don't remember what game...]
