Summary	02699: tkdensho, tkdenshoa: [possible] character misalignment when scrolling
Description	Background floor and character sprites are misaligned when scrolling in-game in all stages. If I had to guess, it looks like missing linescroll (parallax effect like in SF2).
Steps To Reproduce	Start the game, preferably 2-player-vs, make the screen scroll by walking left/right and look at the character's feet. It's easily visible on the 2nd player that's standing still.
Additional Information	- happens in 0.128 official version too tkdensha -> tkdenshoa in 0.133u1

Flags	Possible
Regression Version
Affected Sets / Systems	tkdensho, tkdenshoa

This doesn't look like an emulation bug. MAME is set to pop up a warning if anything actually writes to that area but the game never does. It looks odd, but I'd want real hardware verification that there is a missing effect before any work is put into investigating it.

And Haze, I played arcade version of jojoba in Taito Station in the same place. I confirmed that the message of combo count for 2P is clearly displayed. This (arcade version) is single cabinet with twin control panel type (not twin cabinets with single control panel). I inserted a credit then press 2P start button. And selected story mode with Hole-horse as player character.

No.04660 Tafoid Administrator Jul 19, 2009, 21:13	Per some comments from Haze regarding another possible BTANB (01172) - I'm setting this back to a confirmed/possible state.

No.08107 hap Developer Jan 29, 2012, 23:02	Thanks, will mark it as BTANB
