Torlus wrote the core many years ago now using the netlist files from Atari. ElectronAsh ported it to MiSTer and attempted to make it run. Rysha (Kitrinx) is now also having a go at making it run. Ash's attempt had bandwidth issues so she implemented dual SDRAM to help alleviate that some. It still has a number of issues. The way the netlists were brought into verilog makes the code extremely difficult to understand.

There were only ever 50 official games released for the Jaguar. So having 30 run isn't too shabby.

Found a full set in a No Intro pack, have updated the testing sheet, here is the breakdown:
Games Playable : 33 66%
Games Runnable: 8 16%
Games Not Working: 9 18%
Total Games: 50

Runnable games load to at least a game splash but you can't progress into the game. That's pretty damn good for a WIP core. Hopefully there is a new one to test soon.

I just played Super Burnout on a real Jaguar system and it was pretty cool and fun. The game starts with the Jag core but you can't actually able to load any race any tracks properly but the Jag core I have is from 2020 February 26...haha that's actually today.

You need to be using the build that Kitrinx posted on the discord a week or so back, which also requires dual ram. On that build Super Burnout is playable.

Thanks for the heads up but I must be blind because I'm not seeing it in the "test-builds" section

It was posted in one of the chats rather than the test builds section, I don't have it to hand to post I am afraid. Maybe Rysha is willing to post it test builds, or compile an updated one, or she might be wanting to work on it more before a proper test build is released.

For anyone looking for the file on Discord, filter for Kitrinx and select the posts with embedded files only. It was posted at the end of March 2022.

There is no download link, go to the discord server and search for the post Kitrinx made.

Not everyone is on Discord. It should be trivial to attach this rbf to a post here.

As Kitrinx didn't share it outside of Discord it feels not okay for me to share it on another platform.

Unless it's in a private chat or explicitly asked not to be shared, I fail to see the problem. Both forums and Discord are public platforms after all.

I don't really care for the rbf myself, it's just it's not the first time when Discord sounds like some sort of special club. And I'd rather think we're one MiSTer community.

This is the atari jaguar core I have used but does need dual sdram.

It's not a special club, it's public and open to all and everyone here has been invited in the post below. As with this forum, anyone with a web browser can access it.

viewtopic.php?t=1964

If the Jaguar core was really worth sharing widely it would have already been done so by now. The way the core stands now, it's really unstable. It also uses an unsupported configuration (Dual SDRAM modules).

I'm well aware of how Discord works, but we're here on the forum, and there clearly is interest in the core (unstable as it may be) so why not just post it.

Which is what Annette has just done (thanks!), it's been downloaded several times already, and we can all move on.

It's fine to share it, just be aware that it's pretty unstable. Some things work okay, most things eventually have problems.

Lets not get all tinfoil hat here. The mister discord community is a good place to be if you want to be on the bleeding edge of core changes, as there's regular test builds for feedback, 1 on 1 debugging of issues, and other things that benefit from a live chat medium.

Yes, but these are not the same TOS. At the time of accepting the TOS of a service it also matters what the terms are, who controls the service, and often, where they are. The MiSTer forum's terms do not include a clause like this: "...disputes that are not subject to arbitration will be resolved exclusively in the state or federal courts in San Francisco County, California, and you and Discord both consent to venue and personal jurisdiction in these courts". Being in Spain, that's a problem for me. Not that I plan to have any such dispute, but accidents happen. There's a reason why legal insurance exists, and I don't have one.

So, I'd say it's much more relevant to mention that Discord is not actually open to everyone, but only to those willing to register, than to say the same thing of the forum, even though many people still prefer not to register.

If it were IRC, things would be different. Many IRC servers do not require registration nor acceptance of any TOS, and that *is* open to all and everyone with an internet connection. It's also a chat, allowing for many of the things that Kitrinx has mentioned.

Chris23235 wrote: Thu Jun 23, 2022 5:41 am I guess this means you would say the sentence "The MiSTer forum is public and open to all end everyone." should be modified to "The MiSTer forum is public and open to all end everyone who accepts the MiSTer Forum TOS?"
More exactly, to anyone willing to register (accepting the TOS is implicit in registering).

I know I should not have replied, sorry. I won't reply to any other posts related to this.
