You have a Unicode bidirectional override character in your GitHub display name. This ends up in the “real name” field for commit messages for squashed pull request commits. It causes display issues because the commit message is displayed in reverse order. Please fix it.

@cuavas fixed!

Thanks. Do you know how it got there in the first place?

(Using these characters to screw up page display on forums used to be a common attack in the early days of Unicode support on web forums. But we’ve now seen a trailing U+202E character in multiple GitHub display names.)

@cuavas fixed!

@giulioz
Your PR was committed to source and Dev is still looking for the ROM data that matches it for verification. Please send this in via the instructions on link posted earlier ASAP.

Thank you for your contribution.

@Tafoid I sent it, but I'm getting an error:

The recipient server did not accept our requests to connect]

Any other option?

[Tafoid]

Odd. That was attempting to email?
I'm emailing your Github connected email - simply reply with any DATA or supporting documents (manuals/pcb pictures/etc).

Thanks!
Tafoid

I Have found waverom A & B for the 880 but they have different hash.
did the waveroms ever got some sort of revision?
