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.

Pop Flamer appears to run on identical hardware as Naughty Boy.
The dipswitches are even identical. Spooky.
