|Tester||rhurst||View Status||Public||Platform||MAME (Official Binary)|
|Assigned To||couriersud||Resolution||Fixed||OS||Windows XP/Vista 64-bit|
|Version||0.127||Fixed in Version||0.129u5||Build||I686|
|Summary||02212: bzone: vector drawing corruption when using a save state|
|Description||Game plays, just a variety of vector lines draw off-screen when using a valid save state.|
|Steps To Reproduce||Works fine after deleting sta/bzone folder and running Battle Zone. Launching a 2nd time, and when state successfully loads, vector line-drawing goes jittery.|
|Additional Information||I also tested in a separate directory under Linux using sdlmame 0.127, and it exhibits the exact same behavior upon re-using a save state. Works fine when it is deleted.|
|Affected Sets / Systems||bzone|
|There are no relationship linked to this issue.|

|could this be related to the change of avg_done in a custom_input (even if it would have been present also before 0.127, in this case)? I thought that since avg->sync_halt was already saved there would have been no problems...|

|Tested again on .128 and still fails. The same behavior occurs with redbaron, another Atari vector game, possibly related to same bug.|

This seems to be a general timing issue. When load ing a save state, the screen is only update half as often as with a fresh start.
More specifically, with a save state, I have to press 5x Shift-P in Pause Mode to get an update, whereas after a fresh start it is 2x to 3x.
Loading a save state does not exhibit the issue at all.
