It seems that whenever I look at a driver, I find something to fix in it
In this case, while looking at TNZS, I noticed that some games, e.g. Insector X and Plump Pop, were quite obviously running at 30 fps instead of the normal 60. This makes a lot of difference in the smoothness, strange that nobody ever noticed. Anyway, this was caused by missing support for sprite banking, a feature of the hardware which was already supported by seta.c (the games running in this driver use Seta custom chips). It's now fixed so Insector X looks better than ever :) The improved emulation also fixed the various gfx issues with Kabuki Z.

Well, on the other hand we have Green beret working at twice fps than normal, only bootleg is really 60/60. Maybe the same problem?
Nice work Nicola! :P
Nicola, keep in mind that the original pcb of kabukiZ is full of gfx errors. There is a lot of sprite flickering.
