Naughty Boy driver by Sal and John Bugliarisi.
This driver is based largely on MAME's Phoenix driver, since Naughty Boy runs
on similar hardware as Phoenix. Phoenix driver provided by Brad Oliver.
Thanks to Richard Davies for his Phoenix emulator source.

The dipswitches are even identical. Spooky.

/* Pop Flamer
   1st protection relies on reading values from a device at $9000 and writing to 400A-400D (See $26A9).
   Then value stored in 400C must be xxxx1001 (rrca x 3) or else reset
   2nd protection relies on the values stored in 400A-400D matching $2690+($400E) (Starts at $460)
   If the values all match then it will jump to 0x0011 instead of 0x0009 (refresh instead of reset)

/* These 'Trivia Genius' roms were found on a Naughty Boy pcb, factory?-retooled somewhat to use 8 2732s instead of 16 2716s. The pcb is a real Naughty Boy PCB, with Jaleco markings. Latest chip datecodes on the PCB are from 85 (on the two proms) but the other chips are dated 81 and 82 (which makes sense if they're formerly naughty boy pcbs).
This may be a hacked/bootlegged version of trivia master, hacked to run on a naughty boy pcb, or (if ALL versions of trivia master ran on naughty boy pcbs) may be a 'second source bootleg', a bootleg of the trivia master naughty boy conversion.
