Context#

This needs some investigation. Discuss ideas and findings on the talk page.

The game contains a jump table starting at 4000:005F and called upon at 4000:005A jmp far cs:[bx+5fh]. The table includes the address 4000:4A40 which is the main routine for an Angel Animation Viewer. The Angel Animation Viewer routine will get called if the offset at DS:3AA contains 0x0D but is not clearly visible anywhere in the ROM.

A debug routine also exists at 4000:CC6E but again there is no clear usage.
