Because King's Field II has 200 monsters on its maps this week I've worked on increasing SOM's limit up from 128. The player only took me a day, but SOM_MAP took more than few days.
All that's left to do is to add the extra data to the save file. In a normal software project changing the limit would just be typing in a new number, but with SOM it takes a week! But it's worth it. The problem with this case is this is a systemic part of the program and in all except MapComp the data is fixed by the program's code. I wouldn't normally mess with this kind of thing under the circumstances but for KFII I make an exception, plus the map elements are on the periphery of the system, so they are easier to monkey with than the SOM_PRM data tables. I think From Software set this number too low to begin with and now there is a layer system which means there's more vertical real-estate to fill with monsters!
