Regression found somewhere between 0.97 and 0.98. Whatsnew examination strongly suggests 0.97u3 as the actual regression version:

Major video update to Taito F3 driver that amongst other things properly
implements zoom & column scroll according to how the hardware does it,
which not only fixes glitches in various games but allowed many hacks to be
removed also. Sprite & tilemap clipping is also implemented, as is
proper priority mixing and alpha-blending on the vram and pixel
layers. [Bryan McPhail]

some incorrect assumptions in alpha blending handling are being violated here;
line data 72xx is b00f, changing lines to e.g. 700f causes vram to display.
