it seems overall height / width of the tilemaps can be configured somehow

darkseal clearly needs 64 rows, whereas other games need 32.

width seems configurable in a similar way, with nitroball and lockload

needing narrower tilemaps. lockload/dragngun might be a good study case

as they run on the same harwdare, and both rely on different behavior.
