BYOND 499 limited the number of icon states that can be added to a DMI to 512 states. Why? Who fucking knows. Magically, DM can't edit them but the server doesn't care how big they are, so it's probably a shitty hack so they don't have to change the array's index type.

Whatever the case, we ran into this wall. You cannot edit items_lefthand and items_righthand with BYOND anymore. We filed a bug report: http://www.byond.com/forum/?post=1507331

They closed it with "Not a Bug".

So, here we are. The only way to edit DMIs that big is with third-party tools like OpenBYOND.

How to Compile

Simply dump your DMIs into the appropriate folder and run compile.py from within this folder. It'll build the DMIs and jam everything into a single meta-DMI for you.

Simple.

Adding More Output Targets

If you've run into the problem mentioned above with another DMI, have no fear: Just edit compile.py and add the new output target to the ToBuild dict as shown in the comments.
