Exophase has Temper, the best PC-engine emu ever but has hit a snag with WiFi and won't release.
You've got the story all wrong. It's more like the wifi core is working fine, I just need a few more days to get the GUI in place and polish up a couple things and it'll be ready for release. Lately I've been busy with other things and this is the sort of stuff I'm not enthusiastic about doing, so it takes a little longer than usual. I'll also be out of town this Friday and weekend. But it's really close to being released, don't think that it's on some kind of indefinite hold.
To me I have to say I am a bit dissapointed by the menus in the emus. No button configs, bad ROM selectors have you weaving your way through a cryptic linuxy directory tree everytime you load them, no overclock functions built in (loading that separate app everytime you want to change speeds is a PITA.) Then some menus REQUIRE you to pull out the stylus and use the touchscreen because the coder didn't feel like changing the interface to be useable with a d-pad etc.
And this is why I don't rush a port out, to get simple usability concerns like this taken care of.
Re: gpSP - there are like three people looking at it, it's just kind of tricky to get working. notaz could probably do it with his eyes closed, but his plate is super full right now. As said, I'm definitely not working on it - this isn't just a matter of being lazy or stubborn; since I'm actually really serious about doing another GBA emulator I see working on something like gpSP as in direct conflict to that. Time is better spent on the longer term but more meaningful investment, and I don't want to exactly write two competing pieces of software.
