galaxian.cpp: Video and timing updates from #3783 [kazblox] * Correct sync in Take Off, Explorer, and set 2 of Amigo. Sidam bootlegs of Konami games have a 12MHz pixel clock with video being scaled by two pixels instead of 3. * Correct Jump Bug background hardware behavior, as per real hardware. Stars actually show up until the 232nd pixel. * Correct bullet behavior in Scramble. Shells are now two pixels long, and have been verified on real hardware. * Fix(?) clocks on jungsub. The Subelectro 113 board has no XTALs, and I am assuming the CLK lines come from the pixel clock on the Konami L-1200-2 board. * Given Take Off's hardware hierarchy, correct the year from 1980 to 1981 as a guess. * Correct machine setup for Take Off, Explorer, and set 2 of Amigo. All are now correctly set up as per the 12 MHz pixel clock. * Mark Explorer and set 2 of Amigo as MACHINE_IMPERFECT_SOUND. Explorer requires the same sound timer as Take Off, which I have no idea how it works. The latter probably has a similar case, although it might be different from Explorer. * Mark Take Off as MACHINE_WRONG_COLORS. See the reference video for more; some colors that are purple with the default palette_init are green on real hardware. * Correct background hardware on SF-X and Monster Zero to now show stars and RGB backgrounds. Colors may not be correct, and the current schematics scans are not easy to read. * Converted galaxian.cpp to use MCFG_SCREEN_VBLANK_CALLBACK. * turpins is likely more derived from Super Cobra hardware than Scramble hardware. Change the set description to match this statement.
