BIOS question.

[EFX]

Hi,

I have successfully soldered (piggyback) and flashed my new Bios using Dreamshell RC3.
I wrote the Link83 Bios 1.0

Is there a bios that automatically boot on SD without the Dreamshell CD ?

With the Link83's Bios I tried to change the region of my DC, but it doesn't write the change. Any hint ?

Thanks

If a keyboard is needed, I don't have one.

I have flashed "SD LOADER WITH.BIOS" it doesn't have this issue.
Is there a page with the BIOS description ?

Thx

Thank you very much. you are great help.

1/ I did the R512 mod and now I can write the changes.

2/ as the screen is down I'm not going to see what I type. Anyway, I'm going to try in "blind mod"

[EFX]

vmode -m -d 4 (NTSC) worked for me

vmode -m -d 6 (PAL) let the screen in the same state that it is in the picture attached.

BTW my console and monitor is PAL.

Possible to have pal with the screen centered ?

If it's not possible, how to save ? thanks

I would like to report that

REGION CHANGE:
--------------------

- Doesn't write changes with DS_CORE.BIOS
- write changes with SD LOADER WITH.BIOS

SDISOS/CUSTOM BIOS
--------------------------

Most of SDISOS games doesn't work with both BIOS (DS_CORE.BIOS, SD LOADER WITH.BIOS) but works great with "Original Bios" + BootCD.

[megavolt85]

Flash BIOS from this topic and replace on SD card DS_CORE.BIN. With this bios games work how with "Original Bios" + BootCD.

Цитата:If it's not possible, how to save?

1) download in attach startup.lua.zip
2) unpack and replace /DS/lua/startup.lua

DS_CORE.BIOS doesn't have flashrom syscalls so any flashrom operations is ignored.

Is the boot_loader_unlock_G1.bios region free?

[SWAT]

DreamShell is region free in general. Boot loader doesn't boot the games, only DreamShell, so it's doesn't matter.
