How exactly are you going to have a new FC soon? If you discovered a method to change it, I'd love to hear it. Hate the fact that my FC starts with "0920" (Hate zeros as the first or last number of the initial part of the FC)
I'm designing my own entertainment cabinet for my man cave, to store all my systems, then I'm also designing a power supply/HDMI switcher so I can switch to whichever system I want, and power it also. Already picked up the cabinet board, but tinkering with my drawings before start
But yea, I have frogger arcade cabinet that I gutted and put a Pi4 then Pi5 into, but it never gets played much anymore, should sell it. Even when the kids come over, they don't want to play on it, just the xbox. TMNT and Simpson's arcade is still so fun on it, esp w 2 players.
Anyways, you can do change the FC without formatting with GodMode9.
