Details:
The major differences between install and portable modes should now be:
1. Portable mode doesn't use the registry at all.
2. Portable mode uses the folders inside pcsx2 folder as default (install mode has some default at "my documents").
3. Portable mode tries to save relative paths at the ini file where possible*.
Specifically, portable mode now allows to select custom folders for plugins, bios, etc via the standard UI, which allows using several portable pcsx2 folder sharing the same resources (bios, iso, memcards, etc).
* Relative paths where possible = the following sequence (thanks to pseudonym for the brilliant idea):
1. If the file/folder is inside pcsx2 folder, it's saved as completely relative (to pcsx2.exe)
2. Else, if the file/folder is at the same drive as pcsx2.exe, it's saved as absolute path without the drive letter (e.g. /ISO/...)
3. Else, saved as absolute path, including the drive letter (for linux, without drive letter naturally).
This allows to create a removable drive with (one or more) pcsx2 folder on it, configure all the files/folders to point to the same drive (ISOs, save states, etc), and then take this drive, plug it into another computer (where it will be assigned with a different drive letter), and everything will continue working.
Please test it if you can. Bugs here can be inconvenient...
