4.5. My system starts to load a game but then displays a message like this:
"DISK I/O ERROR", followed by a error code in brackets. I can only power off
afterwards, what's wrong?

There are different error codes for specific conditions but you mostly see
these:

0000 = General error. Clean disc and try again.

0001 = Read error due to damaged/dirty laser lens or disc.

0002 and 0003 = Mechanical problem or copy protection alert.

If you see one of those codes popping up, power off, let the system
cool down, then use a Q-Tip and pure alcohol to CAREFULLY clean the small
lens that sits on the CD reader. Don't use any force, just carefully wipe
it and make sure there's no residue or fuss left.

Next, check the game disc for scratches or dirt, clean it if necessary but
don't use any alcohol/cleaning fluid, just a fuss-free cloth.

If the error messages still appear with one game but not with another
the game disc may be faulty. If the error messages pop up no matter which
game you put in, there may be a problem with your CD reader unit.

You may want to check out some online stores (see 2.3) and ask for a CD
reader unit replacement kit. Also don't forget to visit some internet
message boards like www.neogeocd.net or www.neo-geo.com to browse for more
info or to ask for help with system repairs.

4.5. 我在自己的系統上載入了一個遊戲，然而卻提示這樣的訊息 : "碟片 輸入/輸出 錯誤"
隨後出現了一條錯誤代碼, 我只能選擇關机, 這是什麼錯誤 ?

依特定情況而不同的錯誤代碼主要有這些, 請看 :

0000 = 一般錯誤, 取出光碟並再試一次

0001 = 由於雷射頭 (光頭) 損壞或弄髒了碟片而造成的讀取錯誤

0002 和 0003 = 遊戲机本身的問題 或 防拷技術啟動

如果你看見這些突然跳出的錯誤訊息的其中之一, 先關机, 冷卻一下,
然後用棉花棒和純酒精細心清潔雷射頭 (光頭) , 不要太過使力, 謹慎的擦拭就行了
確認沒有殘留的污垢就可以收手了

如果仍舊提示錯誤訊息, 但隨後卻沒有第二條訊息出現, 那麼這張光碟可能是壞的,
假如錯誤訊息突然跳出, 且不管放入哪個遊戲都是這樣的話, 那就是你机器的讀取問題了

你也許可以到線上購物確認一下 (見 2.3) 並要求替換讀取設備
別忘了到一些像 www.neogeocd.net 或 www.neo-geo.com 這樣的網上留言版查詢更多的訊息,
或是系統修補方面的幫助




水平有限...將就看看.....

看來那幾個遊戲真的是 copy protection alert ( 防考技術啟動 ) 了.....
