Hmm, I guess the reason for the lack of feedback is that the Chronicles is one of the less popular games in the series...
In fact, I personally haven't even completed it.
Anyways, as far as I tested it everything seems to work fine nice work so far, Mindless!
However, if you place one object beyond the level boundaries that are defined in the *.dat file, the whole level will be screwed up: I tried in the first level of the shadow tribe (for reference, the change I did only changed the byte at address 0x007c in Temp101.obs from 0x90 to 0xa0) and it caused the graphics to screw up, random blue terrain pieces appearing everywhere, and after nuking the palette in the following screens being screwed up.
Guess it's a problem of the user if he places objects out of bounds, but I guess it's noteworthy nevertheless.
