Is it possible to boot retail ISO's with BIOS mod?

[atari2atari]

Just to add some more information for this bug - -

I, too, see the exact same problem, and on more than one modded Dreamcast.


- BIOS modded unit(s) as per mmmonkey's tutorial (http://mmmonkey.co.uk/console/sega/dc-dev-bios.htm)

- Retail ISOs will load and run when booting from Dreamshell RC1 disc AND with SD card with DS folder in adapter

- Retail ISOs will also load and run when booting from Dreamshell RC1 disc and a "blank" SD card with only ISO on it (no DS folder)

- If booted from modded BIOS flashed with "Dreamshell loader with bios" and SD card containing the DS folder (of course), the retail ISOs either: 1) show ISO loading screen and attempt to run 1ST_READ.BIN, but then go to black screen and freeze, OR, 2) show ISO loading screen and attempt to run 1ST_READ.BIN, but then the system reboots and Dreamshell restarts


It looks like some component in the DS folder that is used when booting WITHOUT the disc might be causing the problem?

Maybe a new/different DS folder is required?


I have also tried bootstrapping, load high, multiple ISOs, etc. - - same issue.

I see this on two modded Dreamcasts, using multiple/different SD cards and card readers.


Hope that helps! The software is AMAZING so far, thanks for your work!
