Treasure Galaxy Helper is opensource software I wrote to fill in level 5 satellite codes. It's really only worth using when you get one of those codes in which the first 3 numbers are filled in but no others are. But when you do get that kind of a code, it's very helpful. You can tab over to this, fill in two numbers, all while the satellite opening animation is playing.

This is software for Windows. You will need the .NET framework, which you can get on ninite.com
