GCC Developer Steve Golson left a few comments on the recent video! He actually looked into an older version of the source code to see what exactly happened, and it looks like the code worked as intended at first, but was modified and broke during later development!

@13:46 Yes, it was just an error! I disassembled the earliest version of code I have (this is actually Crazy Otto). It shows the correct patch for all four monsters: 2745: 2A 0A 4D ld hl,($4D0A) 2748: 3A 2C 4D ld a,($4D2C) 274B: CD 2F 3F call $3F2F 274E: CD 66 29 call $2966 277B: 2A 0C 4D ld hl,($4D0C) 277E: 3A 2D 4D ld a,($4D2D) 2781: CD 2F 3F call $3F2F 2784: CD 66 29 call $2966 27B8: 2A 0E 4D ld hl,($4D0E) 27BB: 3A 2E 4D ld a,($4D2E) 27BE: CD 2F 3F call $3F2F 27C1: CD 66 29 call $2966 2800: 2A 10 4D ld hl,($4D10) 2803: 3A 2F 4D ld a,($4D2F) 2806: CD 2F 3F call $3F2F 2809: CD 66 29 call $2966 Note they all have the same CALL $3F2F. So originally we had it working, all four monsters random, and then we screwed up INKY and SUE when we adjusted the patch code to align with 8-byte boundaries. Ok that is seriously depressing.

For all of my "followup" videos (the ones I put the quicker intro in), I tend to use my footnote voice, which is just my normal speaking voice instead of super enthusiastic voice I use for the main videos. Of course that means I get a lot of comments asking if I'm depressed, ha
