some investigations and whatnot on that
the following crash happens:  R2 and R6 are the nybble's value it calls function at 02004598 function at 020045F8 is (indirectly?) responsible for the crash commenting out the call causes the sprite to spawn two(!) chomps, freeing them freezes the game silly me ROM:02172A68 LDR R0, [R5,#8]
ROM:02172A6C AND R6, R0, #0xF
ROM:02172A70 CMP R6, #1
ROM:02172A74 BLS loc_2172A7C
ROM:02172A78 BL OS_Panic
ROM:02172A7C
ROM:02172A7C loc_2172A7C ; CODE XREF: sub_21729CC+A8j it basically reads that nybble and checks it, and purposefully crashes if it's above 1 that nybble tells how many Chomps you want _________________________ Kuribo64 - zrghij |

So the nybble is the number of chomps then?
I'll add that to the sprdb. Do you know if the "unchained chomp" actor is spawned by the chain chomp actor? |

What do you mean rather do it the other way round? You mean if you were Nintendo?
 I'm not sure if you are saying chain chomp does spawn unchained chomp or not Also I wonder why it crashes when you fully push the stake in. Another purposful crash? |

That is just sooo cool looking!
I think this might have some uses, if you can figure out why it crashes One question though, why do you think they would make it intentionally crash? Especially since this was once used in an old level... |

That also supports the theory they placed sprite 0 in some (or was it all?) the unused levels, to stop them being used/developed further.

Those are probably just leftover entries.
The beta had different sprites, like for example the checkpoint rings. Those sprites are gone from the levels that used them. As well as the pipe cannons for some reason. (and it appears that those were different too) _________________________ Kuribo64 - zrghij |

Yep, pipe cannons were definitely different. Maybe those sprite 0s are the missing objects with all values (including location) set to 0.
