On the Neo-Geo screen

caveat: some details might be wrong/incomplete/missing

This screen, called the "eye catcher" screen by SNK, is a game-specific feature. There are three options:

• No eye catch
• Standard eye catcher
• Custom eye catcher

If the standard eye catcher is used, the game must provide all the data. This is why various games (ADK's games, Viewpoint) use variations on the Neo-Geo sound. In the main CPU program ROM header, here is a description of th eye catcher fields:

$114 byte  "eye catcher" (screen before attract loop)
           0 - standard NEO-GEO screen
           1 - custom (example: Psikyo screen in Strikers 1945 Plus) (TODO does this use 1 or 2)
           2 - none
$115 byte  defines where the game stores the standard Neo-Geo screen's tiles (apparently games needed to provide that themselves?)

where the number on the left is the ROM address. So for NAM-1975,

0000110: 0000 1000 0138 0000 0400 0000 0648 0000  .....8.......H..
                   ^^^^

shows that NAM-1975 merely uses a custom eye catcher. - Andlabs 22:01, 18 April 2013 (EDT)

Interesting. I did not know. I was just browsing through Kawak's sound feature and heard the jingle. I figured I should mention it, however, I do not know anything about opening roms and such. Still reading the documentations this site provides. But I still don't understand why the eye catcher doesn't show up in that game. Anyways, thanks for the explanation.--RandomName 22:09, 18 April 2013 (EDT)
