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'.
