Is there a GBA backup device that allows users to backup & restore edited save data to/from GBA ROM cartridges?

Hello, is there a GBA backup device that enables users to backup & restore edited save data to/from GBA ROM cartridges? What's the website where I can purchase the GBA backup device from? I need to backup and edit my save data using PKHeX, and reset the real-time clock to 0 days because my internal battery has run dry. This will also allow me to access Mirage Island forever because the seed will always be 0000 bytes.

Hello, there are several options, I recommend that you watch the videos and decide. There are three that I know of:

1. Use a DS Lite.

2. GB Operator (Epilogue)

3. GBxCart RW
