Never, ever, ever, ever access large amounts of data (more than will fit in the system cache) from a slow drive (i.e. DVD) via memory mapped files; you will kill Windows (or at least make it wish it was dead).
I am a graduate of computer science and biology (molecular biology and biotechnology specialization) looking to get into the game development industry. I have been staff at Campaign Creations since 1998, and staff at Camelot Systems since 2001. In that time I've published the popular game modification programs MoPaQ 2000, MPQDraft, and ThunderGraft, and done a variety of game reverse-engineering projects. The last few years, I've taken up linguistics as a hobby, with special interest in Japanese, Latin, and Trique.
