Ymir

[secreto7]

Only available on Linux & Windows at the moment

I saw at github that Wunkolo helped implementing the Mac version, but I think it must be compiled manually for now. Wunkolo also was implementing some automatic dev builds with each new commit.

 

[Gabrinius]

It's good, but not good enough. Ymir's dev already promised Internal Resolution scaling, something I eagerly want, but Mednafen will never implement.

that's something to really look forward for... i'll want to test it once this feature is avaliable.

 

[secreto7]

The automatic dev builds are ready, to download them you need to be logged on Github and search the commits on the Actions tab, or use the nightly.link service.

I am wating for CHD support... al my saturn games are CHD format

 

[Waffles's iconWaffles]

The SEGA Saturn needs more love and I'm honestly glad that it's finally getting it.

It has a pretty wild library that most people don't even know about.

I don't think so? Post a print of the error. I'm playing the USA version of Guardian Heroes.

It's working now, i deleted the emulator and downloaded it again.

 

[thecrow2313]

I have nothing but positive vibes for this emulator. I hope it gets mpeg decoding support.

The other time I thought the automatic builds artifacts were ready for downloading but it seems they only were testing compilation.

They're working on CHD support & 3D control pad

This is my big wishlist item as well. I like Mednafen well enough, but it's probably the only emulator I regularly use that doesn't support CHD files.

I've been trying out Ymir a big on my Linux machine. I'm excited for the progress it's made, and it seems the dev has been making rapid progress as well.

 

[secreto7]

A pity that CHD isn't really lossless, and have some trouble with tracks, if not I would have started using it.

Hi and thank you for your hard work on Ymir! As far as I know there is but one Sega Saturn emulator that is able to support Video CD Cards/MPEG Cards today and it's called Nova. Nova is unfortunate...

It does warn in the code regarding tracks can be omitted. Convert with caution. This is the debate everyone talks about regarding saving disk space by converting to CHD. There is other conversion methods. You can revert back. .GDI is Sega Dreamcast GD-Rom dumps.

for /r %%i in (*.chd) do chdman extractcd -i "%%i" -o "%%~ni.cue"

for /r %%i in (*.chd) do chdman extractdvd -i "%%i" -o "%%~ni.iso"

for /r %%i in (*.chd) do chdman extractcd -i "%%i" -o "%%~ni.gdi"

But I think somewhere it said for that to work it have to include data/info that's not on bin/cue dumps, and nocash said something about not preserving sectors correctly.

I've had that happen when the game wouldn't boot so I ended up reverting back the conversion of the disc. In some instances for example some mod or hacked disc, it wasn't worth pulling my hair & stressing over it so I left it as is.

 

[secreto7]

To be honest I have not enough knowledge to comprehend all, but I try to read all nonetheless.
Of all that I linked and readed, I don't know if even the method of cue/bin that redump uses is good enough to preserve all aspects of the discs.
For the sake of simplicity and to avoid more confusion I use the validated Redump cue/bin dumps.
Nevertheless I hope that preservation keeps developing better, and that CHD or new formats be ready to use.

I totally agree with you
