ChuChu Rocket! Online & Dreamcast ID

[pcwzrd13]

It seems there may be an issue with DreamShell and playing ChuChu Rocket! online. When creating an account in ChuChu Rocket, the account is associated with a unique ID which I believe is stored on the BIOS chip. If you try and log into the same account from a different Dreamcast, it will give you an error. So here's the issue. It seems that with the DreamShell bootloader flashed to the BIOS, this ID changes every time you boot. I've confirmed this with Shuouma who hosts the ChuChu Rocket! server. He noticed that my Dreamcast ID changed from one login attempt to another. This results in a password error if I try and log into the same account again.

Is this something that can be fixed?
