+CAVE's venture into PC based hardware platforms. The game did not 
+sell that well and was plagued by BSODs and hardware issues. The 
+motherboard bios version that shipped out with the game is F2 on
+a Gigabyte GA-MA78GPM-UD2H board
+( http://www.gigabyte.com/products/product-page.aspx?pid=3016#ov )
+
+The following versions are known to have existed.
+
+1.00 - released 2009/05/14
+2.00    
+3.00 - sometimes scrolls the text "2ND UPDATE MASTER VER 3.00" at
+       the bottom of the title screen
+
+The archive contains the following:
+
+./images, documentaiton 
+./cf_card_2gb, a dd image of the 2GB CF FLASH card
+./usb_drive, the game is updated using a USB drive and will not
+  start if it is not present
+./motherboard manual
