Mushiking The King Of Beetle, SEGA 2004, NAOMI M2/M3 Prototype Cart

Even though there is no game name sticker on the cart the serial number
on the the cart shell matches that of the PCB as well as the serial 
numebr stored in the secure FLASH.

There is no EPROM

Cart is populated with 11 FLASH ROMs.

rom8,9,10 and 11 are unused and filled with the same pseudo random pattern. 

The actual game resides in rom1 to rom7.

The dump has been validated against the ROM TEST checksums.

The header in rom1 is incorrect. SEGA did not bother changing the 
checksum during development.

Comments from MetalliC:

Game has no any protection, neither cartridge protection or RFID

Game data ISO file system built about month before release (28.04.2004 this
dump and 31.05.2004 release)

This cart is early version of Mushiking 2K3 2ND English, from early May 2004,
about a month before the final version. (possible based on Japanese 2K4 1ST 
ver, as said in ROM header). 

Observed differences with final game: supports 6 x less Beetle cards, 
uses Japanese "License cards" and has no "Management Chip" (RFID) protection.
"Management Chip"s decremented a counter at each coinup in English Mushikings.

Cart type      : M2/M3
Game Id        : MUSHIUSA '04 1ST VER0.900
