Summary 02269: buckrog and clones: Guessed VCO voltage and the title centering issue.
Description VCO voltage : 1.43 Volts

Note! This is guessed to make the sprites a reasonable size. A shot of the title screen after coinup from a real machine would help to fix the real voltage and give the correct sprite sizes.

Note in MAME the Buck Rogers title isn't centered because of the guessed voltage, though I'm sure it's very close.

Is it like that on the real machine?

The "BUCK ROGERS" title is now fixed and the VCO voltage also (video\turbo.c)

0.129u3: Added calculation for caps >= 100pf to buck rogers LS626 frequency
calculation. Formula was derived from figure 6 of LS624/628/629 &
625/626/627 datasheet. "BUCK ROGERS" is now centered and big ship
appears centered over br's ship. [couriersud, Guru]
