* 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.
Out of what's new:
This set is verified
removes the botched silver land conversion set as the program roms where from the unprotected set_entry
9.2t has bad bits, it's replaced with the new dump which matches the bootleg
New Clone Added
------------------------------------------
River Patrol (Japan, unprotected) [ShouTime, Henrique Areias Pontes, Dane Biegert, Evan Korzon, Mario Mantese, Smitdogg, The Dumping Union]
* pacland: sprites bugfix
Fixed the difference with real hardware:
- fixed: incomplete priority of sprites on fg
- fixed: sprites could not be displayed at the bottom of the screen
* Update pacland.cpp
* It's generally not a great idea to do integer ops on bool - it implicitly casts to/from int and may perform poorly
* Get rid of required ram_device in atari 8-bit common state - it isn't required/used by bartop52
* Get rid of bogus RAM device in bartop52
* Restore some authors' stylistic choices
* Make some stuff more consistent
