I registered for this sole purpose. I've been all over the internet trying to figure out why Super smash bros rumble and warcraft tower defense just wouldn't work on my DSTT. GBAtemp is where I found the most answers. Problem was, there was always a group of people who said it did work, and a group of people making the topic, but never getting it to work. I'm hoping to set that problem straight with this topic. I originally couldn't get it to work, but I did get it to work today. I have a 4gb Kingston microSDHC card. I still haven't gotten those homebrew programs to work on it, however, my 1gb Kingston microSD, it worked everytime using DSorganize. I literally tried to do everything I could to make it not work, and it worked. So I'm assuming the problem occurs with microSDHC cards though it's just a theory. My question to all of you is, what exactly could be the difference between microSD and microSDHC and why does that difference make it not work on microSDHC cards? More over, does anyone out there have any solutions I could test?
