GBA2PSP-UI v1

Initial version of Windows build of GBA2PSP-UI

By design, you can not specify replacement assets for ICON0/PIC0/PIC1/SND0.
If they are missing you will need to add them to the database. You can do this via the github UI which will build a new version of gba2psp-ui for you.
Once it looks nice, use the github ui and create a pull request and I will add your changes to the database.
