How do I get past the set time and date screen in NullDC?

Recommended Posts

I have mapped my keys but after setting the correct date and time; I can't exit the screen and continue! I've tried pressing all of the buttons including Start when I have Select highlighted but it won't exit the screen and go further!

 

How do I get past the set time and date screen in NullDC? :unsure:

Your flash file is corrupt.

Do you mean the dc_flash.bin file? :unsure:

Yes, that one.

 

Alternatively, deleting the dc_flash_wb.bin file might help. Maybe.

I have the same exact problem, I've tried deleting the dc_flash_wb.bin file, then I deleted all my other bios and replaced them with new ones, but when I start the game, it's still on the time/date screen and I can't get out of it. :(

 

Any help would be appreciated, thanks!

Then the flash file is still corrupt. When it is not, any DC emulator will ask you for the date and time only once when you power up the BIOS for the first time, and then let you into the main menu. Do not change the time/date values, just cancel that.

Omg, that was so simple! Thank you man, I feel like an idiot. I just assumed I did something wrong when it took me back to the time/date settings.

 

lol nvm, that was only a temporary fix. It worked the first couple times I started up a game, but I tried again a few hours later and it went straight to the time/date settings again. I don't mean to flood the forums or whatever, but I just don't know what I'm doing wrong. I deleted the flash and flash_wb.bin and replaced them, do I need to replace my other bios too?

No, The Dreamcast stores date/time and other BIOS settings in it's flash memory (similar to some GBA games to stores save data in flash memory). The actual BIOS is a program on a separate chip and it is not altered in any way.

 

The flash (both the physical representation in the DC itself and (apparently) the dumped file which contains the Flash memory are very volatile. Why it corrupts itself so easily is a mystery to me. As a final solution, replace the Flash file with a known uncorrupted version a boot the console up, cancel the date/time questionnaire and then immediately close nullDC the normal way (File --> Exit or whatever it's named). This will hopefully write the flash file properly upon exit. Then boot the console up once more and see if things have improved.
