- Premise:
- Allegro 5 is the main lib.
- All Allegro 4 stuff is handled by Allegro Legacy, linked to AG5
- CLassic Quests play in a background running process of ZC 3.xx (Legacy Environment)
- on top of ZC4 (New Environment).
- New quests run entirely on new environment.
- No emulation is needed, nor do new quests need to maintain compatibility with
- legacy quests, as the old software runs invisible over the new, with input and video
- output being translated.
- All old quests run in this 'Blue Box' module, running on top of 'Yellow Box', invisibly to the user.
