It might be near time for Saturn core to get its own subforum here. :)

Anyone who's tested the beta, could you mention how it handles save files? For example, PSX core creates one save file (virtual memory card) per ROM folder. Wondering if Saturn core is similar or works another way.

I second this. Saturn should have it's own subforum as well as the Atari 7800/2600 core.

Exciting times!

On another note, that seems to be a fair amount of code for CD support, are there no common functions in the CD infrastructure that could be used by all of the systems? (Looking at that code I see similar for PCEngine and MegaCD, though how similar would take some digging)...

Consolidating is often a false economy; if something needs to get fixed on one console, currently only one console's operation needs to be verified. Consolidation would amplify the amount of testing required, and likely increase the complexity for anybody to work on the internals. In order to justify this, there should be some real tangible benefit, but I can't think of any.

srg320's Github repository for the Sega Saturn is here should you wish to compile yourself. Do remember this is an early work in progress, see the README.md for more information.

I think there's a problem with the repo. During the build process, there are some relative paths to seem to leave the project folder. For example:

Yes. You need to grab the 'Saturn' repo and the 'SH' repo.

Saturn: https://github.com/srg320/Saturn
SH: https://github.com/srg320/SH

Put them in the folder above the Saturn-mister, and start your build. :)

just use the multinorm bios, no hassle with region

btw it's not a beta, it's not even an alpha build...

Anybody else getting an authentication request when trying to clone the Saturn git repository?

EDIT: No bother, I've downloaded the ZIP file and am proceeding from there.

This has probably been said before, but what do you need to rename the BIOS to and where does it need to go? I've tried numerous combinations.

Thanks

EDIT: Again, ignore my last. I originally tried the boot.rom filename change, which didn't work. Using the multinorm bios worked like a charm. Ta :D

You need to rename the BIOS file to boot.rom

although the region switch in the OSD does not work i think the multinorm should be future proof when the function is available to change the region. or even auto region depending on which game you load, like on PSX.

I downloaded and compiled this, got the BIOS working but can’t run any discs. Am I correct in thinking I need to either compile a new main mister or wait for the next release of it for discs to work?

You need to compile the latest main, yes.

Folder Structure:

games/Saturn/boot.rom
Thanks. I figured it out. Interestingly though, my structure is ~/Saturn/boot.rom and it works fine (apart from games not loading, but that'll be because I've not compoled the latest version of Main)

I'm not sure if anyone is interested but the region free bios works for me and I don't need to mess with changing the system region in the menu

If the images are on the SD-Card ~/Saturn/boot.rom is fine, it is only when you use an USB device that the core automtically looks up the folder in games.

If your Saturn directory is on a USB drive but not in /media/usb0/games just create a symlink from the SD card to the USB drive.
Ex:
/media/fat/Saturn -> /media/usb0/Saturn
or
/media/fat/games/Saturn -> /media/usb0/Saturn

Does anyone have a compiled version they'd mind sharing here?

Edit: Nevemind, I see that's not available to the public quite yet.

, yes, I wouldn’t refuse the compiled file either, obviously at least somehow working :) For I compiled it, it’s not difficult, it’s only long (1 hour 13 minutes :), but it either compiled incorrectly, or I can’t find the right BIOS . And so I can share the file.

For anyone having trouble synthesizing the core on linux, you need to open the Saturn quartus project and remove VDP1_PKG.sv and VDP2_PKG.sv, and then add them again. The developer compiled the core on windows, and on linux the file names are case-sensitive, so the project can't find them.

Here is the Saturn rbf (single RAM version). Put it in the cores folder and then download Sega Saturn BIOS v1.01 (1995)(Sega)(JP)(M6).bin and rename it to boot.rom. You also need the latest Mister unstable build: https://github.com/MiSTer-unstable-nigh ... tBuild.zip
