 == Rewrite FMOPL emulator ==
-<font color="magenta">TODO</font>
+In ScummVM we use well-known FMOPL emulator from MAME V0.37a with some modifications. That was one of the few
+versions on MAME released under GPL. Jarek Burczynski later rewrote FMOPL emulator to be bit-precise,
+but unfortunately for us his work is under GPL-incompatible license.
-This is tough task, as it should be
+What needs to be done is to understand current Jarek's code and write a new emulator. The efforts should
-implemented by clean room RE. Though I think it is doable by a single
+be made to avoid verbatim copying of his code, so license violation will not take place.
-person if he/she will try to fix existing one with new behaviour.
+There are several approaches to do it, and even less are suitable for a single developer. One of good
+ways would be either fix current FMOPL code looking on how Jarek's code works, or fix completely different
+emulator which we have. It was written under GPL by Ken Silverman.
