The audio and video sizes are now displayed instead of "Yes," similar to how it is done in IsoViewer.
You can now select PIC1.PNG or ICON1.PMF video from a file as the background. Just like the selected theme, the preferred background option is now also remembered.

Atrac3 audio now plays correctly. (It turns out that previously, only Atrac3plus was playing.)
The video now plays without being cropped. (It turned out I was testing with a problematic game where the video itself had black bars.)

The BOOT.PNG file now displays in PSP games. Specifically, this has been verified with FakeNP games!

ICON1.PMF now plays!
Object display has also been slightly improved, and text now wraps when the window is resized.

First release!
