/**************************************************************************
 *
 * 39in1.cpp - bootleg MAME-based "39-in-1" arcade PCB
 * Skeleton by R. Belmont, thanks to the Guru
 * PXA255 Peripheral hookup by Ryan Holtz
 * Decrypt by Andreas Naive
 *
 * CPU: Intel Xscale PXA255 series @ 200 MHz, configured little-endian
 * Xscale PXA consists of:
 *    ARMv5TE instruction set without the FPU
 *    ARM standard MMU
 *    ARM DSP extensions
 *    VGA-ish frame buffer with some 2D acceleration features
 *    AC97 stereo audio CODEC
 *
 * PCB also contains a custom ASIC, probably used for the decryption
 *
 * TODO:
 *   - PXA255 peripherals
 *   - 4in1a and 4in1b are very similar to 39in1, currently boot but stuck at
 *     'Hardware Check' with an error
 *   - rodent should be correctly decrypted but expects something different
       from the CPLD (probably)
 *   - 19in1, 48in1, 48in1a, 48in1b, 60in1 have more conditional XORs,
 *     encryption isn't completely beaten yet
 *
 * 39in1 notes:
 * The actual PCB just normally boots up to the game, whereas in MAME it
 * defaults to test mode and checks the rom, then jumps out to the game
 * after loading all 39 games. It is almost like it is defaulting to test
 * mode on at bootup. On the real PCB, it just loads the 39 games then
 * shows the game selection menu. Going into the test mode does the same
 * code check but then shows  a test screen with color bars. Pressing
 * next shows a high score clear screen (if the HS dip is on). Pressing
 * next shows the game dips screens and allows you to set up soft dip
 * switches for each of the 39 games.
