Started working on shadows & highlights again in the Konami drivers.
Atm, I've implemented a better way of blending which keeps the priorities straight. I've also made it generic for the konami driver and improved it a little.
I still need to get it to work properly for simpsons, but it works fairly well in Surprise Attack and XMen.
Notice the glass in the screenshot. In the current fba release, it's all black & opaque. ^^
