Sega Saturn Core in Development

[Beeble]

You have to be logged into github

Then so must the end-user running this script, and that wont work.

You could require the user to supply a personal access token in an .ini file, but I suppose that would leave less tech-savvy users high and dry.

Would it break any rules to have it downloaded by a github user to some place like the psx core was before and distribute from there?

[boogermann]

There seem to be no download links attached to the artifacts.

Then so must the end-user running this script, and that wont work.

If you want a quick and dirty solution that would make it easier on your side.
Do the following:

1. Fork the repository.
2. On the sidebar under Releases, click Create a new release.
3. Click Choose a Tag, pick a tag name for example 20220907 then click on the + Create new tag: xxx on publish
4. Fill up the release title, could be the same as the tag name of whatever you want, then click Publish Release

This will trigger the workflow, compile the core and upload the artifacts for release which will be available on the sidebar under releases.
You can then make your script fetch the assets of the latest release via the github api at

Code: Select all

https://api.github.com/repos/<username>/<repo>/releases/latest

Based on the workflow you'll have 4 assets available. The JSON path for them are at [assets][0-3][browser_download_url]

Code: Select all

Saturn_<tag>.rbf
Saturn_<tag>.rbf.sha256
Saturn_DS_<tag>.rbf
Saturn_DS_<tag>.rbf.sha256

and you'll have the download urls like

Code: Select all

https://github.com/<user>/<repo>/releases/download/<tag>/Saturn_<tag>.rbf
https://github.com/<user>/<repo>/releases/download/<tag>/Saturn_DS_<tag>.rbf

PS: The workflow will compile both versions of the core on the same action, so expect it to take awhile to complete.

And who updates the fork when its a commit behind ?

It can download files from anywhere, it just has to be anonymously accessible by wget or curl

You can potentially make a GitHub workflow that syncs the main branch of your fork with the main branch of srg320's fork if you wanted.

[Akuma]

Sure, but the question in my department is more of a "how?"

Problems to solve:
1. I followed the instructions of @boogermann but I don't see any artifacts.
2. Keep the repo in sync

Hi hopefully an easy fix. Now yesterday i had the core working fine, got a bunch of games to work the splash screen etc comes up. Im using bios 1.0 jap. I also use a usb drive. initially i had the boot.rom folder on my sd card and all the games on the usb drive. all fine. then when i ran update all it said 'no bios' found. ok.. so i put the bios.rom with my games on the usb drive. It worked again. Now running update all back to square one. I think it's the update all script thats messing it up but not 100% sure it's the only thing I can think off. Ive tried put the bios file back the SD card, even having one in each (sd card and usb). What is going on ,, because it simply says no bios found now. yet yesterday afternoon it was working for hours. any help appreciated. its another script getting overwritten changing the destination or something?

Update all doesnt know anything about the saturn or Bios for saturn so it cant be the script

[pepito]

When this CORE will works on the Antonio Villena's Mister?
I remember as SDRAM issue blocking this core working fine.

He uses a non standard 4 chip design as such you cant expect the deveoper to handle a niche non standard design. Easiest way is to buy a standard 2 chip ram and fit that.

Once you leave the approved designs you are on your own

I have written a small script that will update the Saturn core to the latest successful build from the workflow.
It will also look for your Saturn directory and download the US bios if a bios is not already present. If it can not find an existing Saturn directory it will be created for you and the bios will be downloaded into the created directory.
You can find the script on my Github.

(I removed the bios part of the script as it was causing issues. I will release a bios script for Saturn separately later.)

The script didn't work for me. The error I received was "Read-only file system". I really do appreciate your effort though. Thank you

[SwedishGojira]

That sounds weird. It works for me and several other people and I've never experienced that error.
Do you keep your Saturn gamefiles on an external HDD by any chance?

No but I do use a NAS because who doesn't want every single Saturn game at their finger tips. I've never seen this type of issue before

Have mine on a NAS also. No issues here.
But you have the core itself on Micro SD, right?

I messed up part of the script to install the bios. I removed that part and now this is a pure core updater script and hopefully will work better.
I am working on a separate Saturn bios script instead that I will release later.
Try running the script again and see if it will update itself, or just grab the updated script from github manually.

Thank you for testing it out. If you don´t have the fancy ASCII art header that says "v.0.4" when you run the script, then redownload it from github. The auto updating feature was not working properly, but has now been fixed so it should work in the future when it is updated.

update - when i copied the bios file to the sd card or usb card it automatically gets named to boot.rom.rom so i deleted the first .rom (after the boot.) and it seems to work again?! p.s i always had it at boot.rom but maybe i deleted the wrong extension if this makes sense!

Also thanks for the update script above

Just added a helper script to github for updating the dual SDRAM core for those that want it instead of the regular core.

I just ordered a standard 2 chips.
Let's see.

Hi all

Would someone be so kind and link to the latest single ram version?

[djsquare]

Hi all

Would someone be so kind and link to the latest single ram version?

use the update script posted in this thread

[Beeble]

I did overlook it, thanks for the heads up!

[pbsk8]

running that script, it automatically downloads the rbf file for saturn core?

[ntt]

In my opinion the simplest way is to create a free account on GitHub, when you're logged in the artifacts become downloadable - including those of the Saturn core.

It sure does. You will find it in the folder named "Unstable" on the MiSTer menu.

That is exactly what my update script does, except that you don´t need a Github account at all.
