Layer -1

[*b*]

However, you aren't really using every screen on every map are you. O_o

about 90% of all the screens on a map. I know there are a few screens this would be handy on, because I'd like to have grass as well as bushes, but I think that what was suggested in the Inherent Combo Flags thread is better: each combo having it's own undercombo, like the Next feature

now, I'm not saying this is a bad idea, I'm just disputing weather using the -1 layer as a multiple-undercombo solution is

I'm not sure how the game would read it. If layers -2 and under are not normally used by the game at all, then it should be harmless. They may have to configure the source code though.
