Talk:Digital Devil Story: Megami Tensei II

I've noticed that loading the rom without a .sav file present causes the logo to display on startup. It won't happen once a .sav has been created. Similarly, disabling battery backup in the header causes the logo to display every time on startup. The strange thing is, the color of the logo varies based on the emulator used. Nestopia displays it in blue, and I think this is the correct behavior. Nintendulator 0.970 displays it in orange, and the logo is scrambled. The 3/9/12 beta of Nintendulator displays it in blue, and the logo is still scrambled. Loading the game on a Powerpak doesn't display the logo at all, though the intro in general is kind of glitchy.--Skrybe 16:16, 29 April 2012 (EDT)

Interesting - I didn't realize that it always displayed when there is no save present. It suddenly seems a bit less mysterious now that I know that the player is actually supposed to be able to see it at least once, though the multiple colors and the fact that the correct peripheral can cause it to appear is still interesting.

also, on a technical note: There is a variable at address $00FB which is incremented continuously during "idle time" (many times per frame); the color of the DDSII logo is ultimately determined based on what value is stored here at the moment the game begins to display the logo. Because of the way the game handles input, an expansion peripheral would likely cause this value to be slightly different (the input reading routine takes a different amount of time to execute based on what's being read from the controller ports). However, the fact that the color can be changed by resetting multiple times in a row seems strange, since the counter at $00FB is cleared on reset.
