Burger Time

driver by Zsolt Vasvari

hardware description:

Actually Lock'n'Chase is (C)1981 while Burger Time is (C)1982, so it might
be more accurate to say 'Lock'n'Chase hardware'.

The bootleg called Cook Race runs on hardware similar but different. The fact
that it addresses the program ROMs in the range 0500-3fff instead of the usual
c000-ffff makes me suspect that it is a bootleg of the *tape system* version.
Little is known about that system, but it is quite likely that it would have
RAM in the range 0000-3fff and load the program there from tape.


This hardware is pretty straightforward, but has a couple of interesting
twists. There are two ports to the video and color RAMs, one normal access,
and one with X and Y coordinates swapped. The sprite RAM occupies the
first row of the swapped area, so it appears in the regular video RAM as
the first column of on the left side.

These games don't have VBLANK interrupts, but instead an IRQ or NMI
(depending on the particular board) is generated when a coin is inserted.

Some of the games also have a background playfield which, in the
case of Bump 'n' Jump and Zoar, can be scrolled vertically.

These boards use two 8910's for sound, controlled by a dedicated 6502. The
main processor triggers an IRQ request when writing a command to the sound
CPU.

Main clock: XTAL = 12 MHz
Horizontal video frequency: HSYNC = XTAL/768?? = 15.625 kHz ??
Video frequency: VSYNC = HSYNC/272 = 57.44 Hz ?
VBlank duration: 1/VSYNC * (24/272) = 1536 us ?


Note on Lock'n'Chase:

The watchdog test prints "WATCHDOG TEST ER". Just by looking at the code,
I can't see how it could print anything else, there is only one path it
can take. Should the game reset????
