Don't hide sprites behind $60–$7F or $E0–$FF By default, sprites will disappear when they're behind (on top of) tiles $60–$6F or $D0–$FF, as well as the regular font tiles. This is so they won't appear on top of textboxes. We need to change this to hide sprites behind *any* text tile, instead of assuming certain IDs are always for text. |
