He just released it, and actually... (amazingly) it's not ALL bull****. Now I might not agree with this whole paying thing... but presentation wise this thing is frigin' beautiful. When you open it at first everything kinda swooooshes into place, VERY polished graphically.
The mp3 player is also very polished, you tap the left shoulder button and it brings it up. Showed all my mp3s and clicking them (mouse moves the same as psp-oss) started them instantly, it also has options for shuffling, playlists, and a few other things.
It also has like a movie player thing, but I'm not sure if it just loads the movies or if it has it's own thing, plus I don't have any mp4 encoded movies (using PMP of course) so dunno about that. The image viewer thing doesn't seem to work for me either, though the flash demo on the site has it (not that that really means anything).
Also it has a screen that shows your UMD which works well along with two other screens that say MOD and NET. I'd assume the MOD is that developer resource thing (the modules or whatever) and NET... is he gonna add a browser? Now if he could get a working and nice browser on 1.5 ... well I just might be willing to pony up some cash for that. Also there seems to be a window for a file viewer, but that doesn't do anything as far as I can tell.
Ok as far as negatives, it works well but some things are less that intitive. Like there's no option that I can find to actually exit out of the program and back to the regular PSP menu. Nothing happens when you hit home, and if you push start it just restarts psix. Select and the rest of the of the buttons on the bottom don't do anything either. In fact the only buttons that do anything is the analog nub, shoulder buttons, X, and start. Overall I found it a little confusing to use, but damn... if it isn't pretty!
My recommendation is that it's probably the best looking homebrew I've ever seen. However despite the really awesome mp3 player it's hampered by no built in (functional at least for me) file browser or image viewer. Runs eboots and UMD's fine though. PSP-OSS has more functionality overall, but not by alot. And if he actually gets the image viewer and file browser working... well then it'll really be giving PSP-OSS a serious run for it's money (pun intended).
Ease of Use: 6/10
Oh ya, and if what I'm saying is kinda confusing about the interface he's got a pretty nice flash demo here:
EDIT: Fluff told me I was WRONG so I changezed my silly mistakes :P.
