+ Chameleon 24
+
+ driver by Mariusz Wojcieszek
+ uses NES emulaton by Brad Olivier
+
+ Notes:
+ - NES hardware is probably implemented on FPGA
+ - Atmel mcu probably controls coins and timer - since these are not emulated
+ game is marked as 'not working'
+ - 72-in-1 mapper (found on NES pirate carts) is used for bank switching
+ - code at 0x0f8000 in 24-2.u2 contains English version of menu, code at 0x0fc000 contains
+ other version (Asian language), is this controlled by mcu?
+
+PCB is small and newly manufactured. There's 24 games which can be chosen
+from a text menu after coin-up.
+The games appear to be old NES games (i.e. very poor quality for an arcade product)
+Screenshots can be found here....
