Chances are those things will be faster in next version, but we'll see.
On the light gun topic, I sent notaz my PS1 guns awhile back and he's hoping to be able to implement light gun/touchscreen useage for PSX-ReARMed in future if he can figure it out, so perhaps a few TimeCrisis/Pointblank type titles will eventually be possible with stylus/TV Out.
I've visited my parents and played with that on one of their CRT TVs during the weekend. The Guncon protocol (Time Crisis, etc) seems to be simple enough, but I failed to dump meaningful data in the justifier mode. An open source input plugin with gun support has surfaced not so long ago, hopefully it will help to figure out missing parts.
