Indeed, it happens for all BIOS for me:

1) when doing a soft-reset after some specific point during the BIOS animation 
or after the game has been loaded (not always)

2) while in the system menu itself (always)

It must be caused by the way I'm handling soft-reset on the CD side, I might be 
resetting stuff that should remain unchanged (I'm still not 100% sure of real 
behavior and it's not well described).

Shouldn't the tray open itself on Model 1 CD hardware when pressing the RESET 
button ? It doesn't happen in Kega though I think I was sure it was expected 
behavior. Maybe the animation is meant to be stopped in that case ?

Also seems 1) above depends on the game being loaded, some games always display 
the BIOS animation after a soft-reset during game, some doesn't.

At least on model 1 Japanese Mega-CD units, the CD tray always remains closed 
until you press the Eject button from the system menu.

It's quite an awkward behavior, specially since there's no actual physical 
Eject button and all, but that's the only way I know of opening the CD tray...

Word-RAM should be put back in 2M mode on reset, this fixes the logo not being 
displayed properly when doing a soft-reset after it was changed to 1M mode 
(hence why it only happened for some specific games, in BIOS system menu or 
when doing a reset at a specific moment)
