GBA exploader allows for the use of slot 2 flash carts for use in GBA cart emulation. It lets you move GBA roms from the slot 1 card, and place them in the memory of the slot 2 device. Not only that, but it allows for saved games management, and loading GBA homebrew. I think there are more functions, but I havn't used it in months, I just got a new flash cart today. I'll be more knowledgeable later. Now, I'm going to grab the source for DSOrganize and so how hopeless or hopeful it is for me to add the features I want.
I'd like to add a vote o Comic book DS. It really is a great application. I not only have all the Heroes comics, but after converting the pdf's to jpegs, I have a great way to view bus schedules. It really owns. I just wish there were previews in Picto DS that showed how stuff that's going to be converted will look like on the DS. Sizing issues are just try and try again, unless I missed some part of the program, if so I'm deeply sorry.
