Usage of mode 2's special scrolling ability ?

Post by Bregalad » Thu Jun 12, 2008 3:27 am

I'm trying to do some things in SNES dev, and after experimenting a thing or two with mode 7, I'd like to exepriment the special scrolling ability of mode 2. Too badly this seems to be completely undoccumented, I just know something that allow special scrolling exists, as seen on Chrono Trigger's title screen or in Final Fantasy 5's battle background when you summon Leviathan.

All informtaion I can find about it in docs is that "Offset value can be set in H/V direction against the cell". I cannot find any register to handle this tough. Can anyone tell me where I can find more info about this ?

Isn't offset per tile the same thing Tetris Attack uses?

Read the newer documents written by Anomie, not the old crap.

Oh many thanks. This mode is kinda cool. I guess it would be possible to do perspecive effects in mode 2 as well, if you set each tile so that they scroll against each other for horizontal reduction and change the vertical scroll via HDMA for vertical reduction, you get a scaling image without mode 7 !
