IMO this is a really cool app thats going to open loads of options for everyone.
in simple terms on the ps3 start PS3Load and on pc load a .self with wii loader

i hope soon this will lead to loading .self's with arguments (ps1_emu.self - ps1game.bin) via a simple text config file, from usb/hdd/ftp a bit like radshell on the ps2.
edit:
what version of wii loader is best for our needs on xp??
