|Summary||06027: bigkarnk: Game freezes under some circumstances|
The game could freeze in some particular circumstances, with sprites unable to move and music still playing.
It may happen in level 2, inside the pyramid, if the color-changing ankh is pulled it when it's yellow or black (optional in both cases and not needed to proceed). After doing that, the game will possibly freeze when doing any of the following actions:
1) Jumping on a stairs.
2) Touching the top step of a stairs (only when going left).
3) Landing after walking off a platform*.
4) Landing after a jump, if you hit something in midair (wall, object or enemy)*.
5) Landing after receiving a hard hit (like a kick from the mummy boss in level 2).
6) Jumping on a higher platform (unless you land on the edge).
7) Jumping down to catch a rope (only on the ship in level 3).
* = not always, but eventually it happens.
|Steps To Reproduce||It might take a few tries to reproduce. Unfortunately, I don't know what exactly triggers the freeze, pulling the ankh when it's yellow or black is only the final part.|
I currently can't trace a regression (if there is one), given the semi-random nature of this bug.
However, it does seem to happen consistently from recorded INPs. So I have included 2 INPs for comparison, with the freeze happening in only one, even if I did basically the same actions in both.

Unable to reproduce this anymore.
It seems it was fixed in 0.215
Uploaded savestate from mame 0.220, so that anybody can test this with the stairs

It's not fixed yet.
I have confirmed it in 0.238, and that the trigger is during the second stage, while grabbing the ankh while yellow or black, at the "wrong" time.
The crash is intentional. I have an idea of how to fix it.

|Possible related to thoop freeze?|

|Does anyone have an objection to resolving this then? Any idea who fixed it, and when?|

from what I remember: peterferrie came up with a range of hz at which thoop2 will work(not crash) at, then Haze found a perfect hz in that range which matched up with pcb recordings
peterferrie, legendary fix, buddy :)
