Question, since I can't find it on the thread, is there a way to change your town name at all (most likely through hex)?
You can use this method.
My HxD version is in french so I don't have the exact traslations but you'll understand
Open the ram file in HxD (or any other editor) and press ctrl+R (works in HxD), write your actual name in hex in the first search field (if it's John it would be
4A 6F 68 6E, add nullbytes if needed)
Write your new desired name in hex in the second field
Choose "Hex values" as type
And then click "replace all"
Do the same for your town name.
For the text message in the profile card, press ctrl+G and type 6B40 (message start at 6B44) in the search field
You'll see your message and then you can edit it, don't forget to reverse the bytes, E0A2 become A2E0
