* - emulate slave dsp!
* - tokyowar tanks are not shootable, same for timecris helicopter,
* there's still a very small hitbox but almost impossible to hit
* (is this related to video board? or cpu?)
* - fog (not even hooked yet up on not-super)
* - polygon seaming (fix those small gaps between polygons)
* - missing/wrong sided textures (eg. ridgerac race start, propcycl scoreboard)

* + xy offset
* + clipping to window (eg. timecris)
* + eliminate garbage in airco22b
* + some missing sprites in cycbrcycc (most easy to spot is the missing city picture at titlescreen)
* + y doublesize/scaling feature? (cybrcycc)
*
* - lots of smaller issues
