in game level objects and 0x80

[city41]

For in game levels, the byte 0x80 in an object stream, and not attached to any object, seems to signify something.

1-1

At the end of 1-1, there are these bytes:

40 19 80 f 40 18 83 f 41 19 83 f 80 8 42 80 42 1a 8b 9 41 18 91 18 0 12 94 2 0 0 9b 29

I think they parse out to this

• 40 19 80 f a brick
• 40 18 83 f a brick
• 41 19 83 f a brick
• 80 8 42 80 ????????
• 42 1a 8b 9 a bank 1 object with id 9
• 41 18 91 18 a bank 1 object with id 18
• 0 12 94 2 a bank 0 object with id 2
• 0 0 9b 29 a bank 0 object with id 29

so what is the 80 8 42 80 sequence?

4-2

4-2 kicks off with an 0x80 right away

80 42 17 0 5 45 15 8 7 40 14 9 5a 44 16 10 7

If you ignore the starting 0x80, the rest of the bytes do seem to be objects as expected.
