Someone was nice enough to post it to ISOZone. Be sure to read the description, as it is a Dingoo release. There's some key mapping issues, but it works great once you get it mapped correctly. After unzipping, place the folder somewhere on your Zero. Then, navigate to the "emulators" page and press SELECT. Highlight "Add link in emulators," and find your Temper folder. Just select the "temper.dge" file, and you should be good to go. It even adds the correct icon automatically. By-the-way, HuCards must be in an unzipped state to be recognized by the emulator.
