If Argo is referring to
this thread, then there isn't any guarantee (that dosuae F12 quit key could be a coincidence). Anyway, as UAE is GPL AInc could use it without any "deal", as long as they comply with the license. If the GPL UAE is there, the game archive must include the written offer for the source code of the GPL parts. Also, if the game system is tightly integrated with the UAE, then those parts are GPL aswell. The other possibility would be that AInc has contacted all UAE copyright holders and obtained a separate commercial license for all parts of UAE. That sounds somewhat unlikely, however.
I could still take a look, but I am not willing to give any money to AInc myself.
