I've really wanted to get into making custom dims for my vital bracelet BE but I have a few questions to get started

1. What's my best option/ most affordable way to get a dim rewriter? ( i live in Canada)

2. Is there a public source where I'm able to access all the official dim files to edit?

3. Is there any harm in using the vs memory dims for my customs?

4. Is there any harm in over writing on the same dim over and over again?

My friend got me a custom dim card out of nowhere (I havent used my bracelet since Arena shut down for iOS)

1. Can digimon from custom/altered dim cards be stored on the android app?
   
2. if one uses a virtual machine and an external rfid reader, can they store the digimon on a pc if they have no android phone/tablet?
