Checks blocks to see what to do whenever Samus runs into one of them (NOT while Samus is touching them)

X = block type*2
94:953E: Vertical. JSR ($94F5,X)
94:9527: Horizontal. JSR ($94D5,X)

8F47: CLC and RTS - always unsolid

8FBB: Load the BTS AND #$001F. If greater than 5, load the full BTS, put it into $1E77, and JMP $84D6. If it's less than 5, just JMP $8D2B (with the BTS AND #$001F in A)
    84D6: If BTS is negative or Samus is moving vertically, just CLC and RTS. Get the distance ($12.$15) in A, and $8588,((BTS AND #$001F)*4) in Y, and JSL $8082D6. Use 05F1 and 05F3 as new distances.
    BASICALLY: Multiply Samus's movement by (94:8588,X)/(100), X = 4*BTS. The multiplier is, obviously, usually less than 100.
    8D2B: BTS AND #$001F into $0DD4. BTS X/Y flip into $0DD6. Other stuff I'm not going to bother figuring out.
    BASICALLY: 94:8E54 is a table of 4-byte entries for the first 5 special 'slope' blocks. 80 = solid, 00 = air, organized topleft, topright, bottomleft, bottomright.

904B: Check BTS. JSR $902B,BTS (8E83, 8ECF, 8F45, 8F0A, 8F45 for the rest. 10 entries, 20 bytes). JMP $8F49 when done (normal solid).
    8E83: Unless already hurt, deal 60 damage (environmental) to Samus, unless in WS and Phantoon is alive.
    8ECF: Unless already hurt, deal 16 damage (environmental) to Samus.
    8F45: SEC and RTS. Just a solid block.
    8F0A: Identical to 8ECF.

905D: Check BTS. JSR $902B,BTS. JMP $8F82 when done (normal solid).

90CB: Check BTS. If positive, make a PLM from the table at 9139,X (X=2*BTS, max BTS is 4F). If negative, make a region-indexed PLM (91D9 + 20*Area + 2*BTS, max BTS is 0F). If PLM fails to be made, JMP $8F49 (normal solid).

9102: Check BTS. If positive, make a PLM from the table at 9139,X (X=2*BTS, max BTS is 4F). If negative, make a region-indexed PLM (91D9 + 20*Area + 2*BTS, max BTS is 0F). If PLM fails to be made, JMP $8F82 (normal solid).

938B: Store #$E17D to $099C, store BTS to $078F, lookup (2*(BTS AND #$7F) + DoorOut), check to see if elevator or door. Set $078D and $0998 if door, else some elevator code, I think.

93CE: Store #$E17D to $099C, store BTS to $078F, lookup (2*(BTS AND #$7F) + DoorOut), check to see if elevator or door. Set $078D and $0998 if door, else some elevator code, I think.
