In open defiance of all that is sane, I actually got a chance to lay some significant groundwork towards ad-hoc networking. The recent addition is pretty significant, and if all goes well, an ad-hoc capable emulator should not be too far off. (And yes, that is ridiculously vague, but my work [definition: annoyance that pays the bills] and family obligations make precise estimations all but impossible. And let’s not forget about the greatest game ever made being out.)
It has also been brought to my attention that FMPAC still doesn’t function correctly in fMSX PSP, so look forward to a fix of that as well.
