GPL compliance
Starting with the ichorescent release of the OHRRPGCE, we have re-licensed to Dual GPLv2+ & MIT license by the unanimous consent of all current and past contributors.
As always, your games can be distributed under whatever license you choose. This article is only relevant to those who are modifying and recompiling and redistributing the engine itself.
You may use either license that you prefer for your own fork. We appreciate it if changes are contributed back under the same dual license, but that is up to you.
Distributing Copies of GAME.EXE[edit]
If you just want to include an unmodified copy of GAME.EXE (or CUSTOM.EXE) with your game, you should also include a copy of LICENSE-binary.txt which tells people where to get the source code.
You are not required to release your RPG file under the GPL or the MIT. Your game is just a data file. You may still make sure that players know they can have the source code to GAME.EXE.
