Sorry for my late reply. I did it on my emulator since it takes a huge effort to root my phone. But I transferred my data to my phone and haven't used emulator for a while, so I can't be sure 100% that I'm correct.
The code stands for a group of numbers. I forgot what types they belonged to but it's easy to find though. I used GG in my emulator btw.
The number "50" stands for the cost for a Single Item Ruffle. As you can see, make it minus and it will give you accordingly the GPs, and the GPs can be consumed as normal GPs does. Available in ruffles too.
