From Andrew Broad's Manic MIner Room Format: http://www.oocities.org/andrewbroad/spectrum/willy/mm_format.html#special_graphic

"Rooms 0, 1, 2 and 4 have a special 16x16 graphic (see Appendix C) associated with them, which is held in Offsets 736 to 767. On all other screens, Offsets 761 to 767 are zeroised"

Offset 761 actually holds #FF (255) in some caverns, to terminate a vertical guardian list in a cavern with four vertical guardians.

From John Elliott's Patch for Manic Miner:

https://www.seasip.info/Jsw/mmdiffs.html

Part of the source code gives the wrong conditionality, although the actual patch inserts the correct opcode:

"LD A,(B8073)
AND 10h
CALL Z,C9135 ; Kong"

The latter command should read "CALL NZ, C9135"?

**

Also, the "Routine to strip surplus bits from the border colour" at #934C should probably be CALLed from the Kong Beast routine when Kong is making a falling noise, although I can't detect any adverse effects from that omission.

John Elliott's list of the differences between the Bug-Byte and Software Projects versions of Manic Miner:

https://www.seasip.info/Jsw/mmengine.html

omits to mention the different graphics (for Fire 1 and items) in 'Processing Plant'.
