I know some people probably want to quiz themselves on katakana, right? but there's only MegaHiragana on the program...well until they update, I have done it myself.
You'll need to know how to get the keyboard lay out for Japanese Katakana.
Just go to MSpaint (easiest way of doing this rather than photoshop for me. you choose ur program).
Use the Text tool, and set it to katakana. Now put the letter ア.
Save the picture (I'd make the picture around 400x400 pixels, but your choice, jsut don't make it too small) to a jpeg format.
You'll need, I think, at least 5 pictures. So just put 5+ katakana's that you feel comfortable with or have practiced with.
Go to the program, and go to the section "MegaVocab."
Click "MegaVocab Creator."
Browse to the picture. Japanese translation to the pronounciation of the symbol A for ア, etc.
Push the spacebar in the English translation field (so it's blank and you don't know the answer).
Do this until you have the katakana you want.
After you're done, go back to MegaVocab, and make sure "MegaVocab" is checked. Click "GO!" and you have your katakana tests!! 8)
