Summary 08082: tokio, tokiob: Player ship incorrect right banking animation
Description As stated, the banking animation appears notably wonky when moving right in newest builds. Easier to see in action rather than using stills.
Steps To Reproduce Insert Coin, start game, then move right
Additional Information Used this video as brief reference:

Also looked at previous bug reports, in which one video moves the player but doesn't exhibit the issue. Also not present in Taito Legends.

I can't see what you mean at all

I, too, can't figure out how the moving the ship left to right looks "wonky" in any way.
You'll need to be a bit more descriptive and illustrate precisely what you mean and how you achieve what you are asserting.

Play in slow motion (eg. speed 0.2) to see it better.

But! it looks the same in the pcb video.

Apologies for wasting time, it seems hap is correct. I've also used the 0.25x replay to confirm it is present in other videos as well - which is weird because they didn't seem obvious at normal speed when I checked before making this bug report, and it *really* stuck out like a sore thumb when playing it in MAME the other day.

To better explain the effect, upon having moved right a certain amount of frames and then either stopping or presenting other input, the ship appears to have a jerk-like effect on the wings while animating back to it's center frame. This doesn't happen when banking left, only when banking right. Upon closer inspection using frame advance it appears like half of the sprite is actually reverting to its previous frame while animating, but the videos online would seem to confirm this to be a PCB bug and not a MAME emulation issue.
