The bugfixes I've mentioned I made are not released on this site yet. They're only available right now when you download the source code and compile it yourself(the base PSPSDK 10.0 is all that you'll need).
When the SDK is installed(C:\pspsdk in my case), on Windows you can then run remake.bat in the UniPCemu folder, which will compile the app. Using Linux with a PSP devkit you should also be able to compile it, albeit running "make psp build" (without quotes) directly without the batch wrapper.
It's easy enough to compile for the PSP, though. Just download the PSPSDK 10.0 and add the missing encryption package. You'll also need the prx encrypter pack from gbatemp.net (google for it). Then just run the batch file on windows(or make command from Linux compatible) to compile the eboot.
