HDPack - yeah - you just need to zip it up in a specific format. I need to do the documentation at some stage. As a reminder to me, put that as a feature suggestion herE: http://retrorigs.biz/Mantis/my_view_page.php
CRC - yes - because the db is only on the exe CRCs that I know about.
Loader - errr... the terms of your question are dificult to answer. TypeXtra basically executes the file you identify as the Launchfile and monitors the GameExe for termination so it know the game's ended. You can customise what files Typextra uses for these. So, broadly, I 'd guess yes. Don't use teknocarrot and my understanding of GameLoaderAllRH is that it just produces a modified game.exe - so this should definately work with typextra
No. You'd have to create the D,E and F drives yourself via windows mapped network drives. TypeXtra does tell you whether these are available via the checkboxes at the bottom right.
