I have been busy working on reducing the complexity of setting up games with Winulator, in order to reduce the amount of actions required by the user.
Regarding WCH - it would be obsoleted :) I'm working on rewriting and incorporating the bulk of it into the app itself so conversion will be automatic, fast and transparent for the user. This issue gained priority during this month when I discovered some bugs in the conversion. Obviously re-conversion should be automatic, and for that, the app itself need to handle this. Tackling the code that drives the whole-executable static recompilation is arduous, and it would take some more development time on my part.
Lots of people are asking about other games (and StarCraft - it's advancing but not yet full). I'm taking all your suggestion into consideration.
