Can't boot up cdi, nrg images?

[RZetlin]

I am having issues with starting games with cdi and nrg images.

NullDC just boots to the CD playing screen.

When I mount the nrg file with Nerodrive the game loads up.

When I mount the cdi file with Daemon, the game doesn't load up.

Does anybody else have this issue?

[refraction]

doesnt it work with the imagereader plugin?

I tried it out with different games.

Some games can boot boot up okay with the cdi format while some cannot.

I remember a similar issue with Chankast.

Does NullDC require self-booting DC games?

Tried out the same games and it works under Chankast.

The games that don't boot up, I would use the Utopia boot disk.

Under NullDC this method doesn't work.

Any sort of cdi, mds file that I try to boot up in nullDC immediately brings me to the CD spinning music player. Is there any sort of fix for this?

Yes you have to use the call znullgd. Then you mount the image of the game with deamon tools, and it works.

hmmm, it still gives me the same CD spinning when I mount the image with daemon tools and using the zNullGD plugin. I've tried a couple of games of different cd image type and still nothing.

Try using HLE boot instead (File->Hle GDROM Boot).

[Firebricks]

Still the same CD spinning screen :/. Anyone have any other ideas? (thanks for all responses)

[PsyMan]

Try switching back to the image loader plugin and using HLE boot.

[Firebricks]

still the same spinning CD. I've tried several bioses and flash files and still it's the same thing.

Did you set the drive letter to E: when using zNullDG with daemon tools? It could be a different letter if you have more drives.

Even if you select the correct drive the game won't play.

I still get spinning cd. Here are what I think are relevent consol lines

GDROM emulation is one of the more problematic things still remaining. Two methods thus far are two different plugins. One should definitely use "selfboot" images to get the easiest use out of either plugin.

With zNullGD, mount the selfboot image and select the proper disc drive in the options for this plugin. Start the emulator, and it should work properly if the image is good and the game is supported.

With ImgReader plugin, load the proper image and run the emulator with the start option.

The HLE boot is not recommended, the games initial program requires the hardware to be initialized properly by the bios before it will run. We no longer emulate the state of the machine after bootrom has run, we have proper emulation with the bootrom image itself.

Hopefully this clears a few things up. Most of the problems center around poorly constructed images.

I can't get any games to run at all. I have an image of a CDI and an NRG games, but neither work. Tried mounting with daemon tools, tried just loading them up straight, nothing seems to work. I know my images are good because I burned them onto a cd and played them on my dreamcast so.

i used to get that spinning cd with time stalkers so what i did was convert it with bin2boot+gui tool after it was done i left a cdi image with works like a charm

heres the link in attachment btw sorry for my eng spelling i suck at it =D

If the image worked in your dreamcast burned to a cd-r, without needing a boot disc, it ought to work properly in the emulator. Please report what game(s) your trying, the filename, and make sure you have the relevant files needed by the emulator (bootrom, syscalls etc in ./data)

[realworksuks]

i've tried bust a move 4 and rez. I have both the bios and the flash in the data file and named it like the readme wanted. They both work in my dreamcast so I don't know what i'm doing wrong.

I get the same problem with Powerstone 1, and it always booted in chankast (I never burnt it to test on my DC - seemed a little stupid)

That bin to Boot Program worked perfectly, thanks a million
