Hi,
I am a new happy owner of the gaming machine.
I bought a game machine two days ago and when I go to setup then it will ask keychip

but what is right keyship???
Board assy no is 7570390 and stickers P/N is 75703903 REV:B
Base type is
I0000738
01/28/02 (1-4002)
if I buy here
http://www.ebay.ie/itm/IGT-GAMEKING-KEY-CHIP-/262017752915? Key 22 and Key 40 are for non- enhanced boards, So whether they are correct?
And what do you know of these game roms, whether these only one game or more
GME1
G0001323
GME2
G0001323
Will this change the games if I only buy new GME roms?
Here are some images to clarify



I'm sorry for my bad english
Regards, Topi
