Dreamcast widescreen menu ?

[CabbageHead]

I guess the title ist self explanatory, but is there a hack for the Dreamcast bios menu to be widescreen.
I think it would look rather nice to see on a HDTV with a dccdmi mod.

There is a widescreen hex code made by @Esppiral.
But you have to patch your bios by yourself.
I don't know how to do that.

Patching is not a problem.
Do you have a link ?

checksum calculation algorithm where do you plan to get it?

[CabbageHead]

Pardon ?

[megavolt85]

if you change at least one byte in the BIOS, it will stop loading

Sorry to bump up an ancient thread, but if that is the case how did Japanese_cake make the freezone replacement bios?

I don't know how Japanese_cake did it, but I modified the console for brootforce checksum
moreover, you can’t replace a large piece of code and pick up a checksum, you can only change small pieces and sort through the checksum each time
latest bios from japanese_cake use bios from sega aurora slot machine, it allows you to create almost any custom bios, but game compatibility is far from perfect
