Readme file for GBA Jpeg viewer Version 2.3 by Tony Savon

GBAJpeg lets you display pictures in a slide-show fashion on a Gameboy Advance(tm). To create a jpeg GBA rom use the GBAJpegPacker included in the zip file: Open or drop the pictures in the listbox and press the "Create GBA rom..." button. The GBA rom can be loaded by a GBA emulator such as Visual Boy Advance ( http://vboy.emuhq.com ) or uploaded to a real Gameboy Advance using a flash2advance ( http://www.flash2advance.com ) or a similar backup tool.

Usage:
To browse the pictures of your slideshow use "L" and "R" keys on your Gameboy.
Hold "A" while pressing "L" or "R" to skip 10 pictures
Hold "B" while pressing "L" or "R" to skip 100 pictures
Press "A"+"B" to jump to a random picture
Hold Start and press Select to reset or to exit to Pogoshell
Press Select to bring up a simple help screen
Hold Start and press "R" to start slideshow mode
Hold Start and press "L" to switch to thumbnails mode
  In thumbnails mode use pad to move cursor, "L" & "R" to skip a page and "A"
