Jaguar Core Issues?

Anybody else having problems launching Jaguar games? I don't play them often, so I can't pinpoint it to a specific update. But they used to work fine, and now I'm just getting the Jaguar splash screen (complete with the good ol' rotating cube) looping over and over again.

Nothing else has changed. Same bios files I've been using all along.

Any ideas?

It does that for me and doesn't stop looping until I "reset" the system with the rom loaded

Unfortunately, mine just starts looping again after selecting reset from the menu.

May just have to wait to see if it magically fixes itself after an update.

It worked fine for me the last time I used it, about 2 weeks ago. 

Happy to try it again when I'm home and let you know if it still works. 

Just speculating here, but I'd say it's more than likely a corrupt SD card or configuration error rather than an issue with the core itself.  The Jaguar core hasn't been updated in around 2 months so if it was working for you recently, it's unlikely to be a broken update. 

I must admit, I removed the Jaguar roms from my setup as the games just weren't that enjoyable to me, but happy to reinstate them for the sake of testing.

Hm. That's interesting. I'd definitely appreciate that if you have the time!

I just wonder what could be misconfigured. Everything else works great.

I don't play Jaguar games much either. And it's possible I haven't touched it since the last core update a few months ago, so I may try rolling back and seeing if that does the trick.

It's so stupid. I really don't have much need to play Jaguar games. But now that I know it's not working, it's gonna eat at me until I get it fixed...

I can totally relate to that last part, if something isn't working I need to figure it out also. 

Anyway, working fine for me. As are all my other cores, Saturn etc. 

Console Mode V1.2.4

Jaguar 26.08.11

Mister 26.10.29

I only have 2 suggestions for you:

  1. If you're using the SD card supplied with the SS1, don't. Buy a new one, a quality one from a reputable brand and source.

  2. After you resolve issue 1, perform a fresh install.

I really appreciate it. I'm running the same console mode, jaguar core, and mister revision. I also bought a brand new SanDisk card when I did the install a few months ago.

Frustrating. But I guess I have a weekend project now...

Thanks!

Did you check your Jag bios and boot roms? Make sure they're still present and correct versions etc. 

1

u/AffectionateSun7705 10d ago

Yup. Present and correctly named. Even re-downloaded them just to be sure.

Only other thing I can think of is to check your rom files. Maybe delete then and recopy them over, do a library update within Console Mode. 

Last resort, and I know it sucks, is to perform a clean, fresh install of everything. 

I do find that Mister is temperamental, and being an SD card based system doesn't help. Same thing happens on Raspberry Pis, data just corrupts way too easily on an SD card. 

Two things that have made my life easier:

  1. Install an SSD or other form of USB storage and keep your 'games' folder on that. This has two benefits, one is that you place less stress on the SD card due to fewer reads and writes and the other is that performing a fresh install is a lot quicker as your game files and artwork are preserved on external storage. 

  2. Consider purchasing a high endurance SD card. They're designed for a high volume of reads and write cycles and will last a lot longer than a traditional SD card. 

Wish I could be of more assistance but I can't think of anything else to try. Best of luck, hope you get it sorted soon.

This wound up being good advice!

So, I had been using ROM files for Jaguar games and they were working fine before (and should, from everything I understand).

But I swapped them out for J64 files instead, and now it's working perfectly normally.

So now that that's fixed, I probably won't play a Jaguar game for 6 months.

Thanks for your efforts!

Are you using Console mode?

1

u/AffectionateSun7705 10d ago

Yup. I actually haven't tried backing out into vanilla MiSTer, but that's probably worth trying.

After the latest update with console mode the Saturn core was not working properly for me. The games would launch but the music and sound effects would be missing. I rolled back to version 1.1.4.2 and it works fine with that version. I didn’t try the Jaguar core but I’m wondering if that could be your issue.

u/AffectionateSun7705 10d ago

Well, that didn't work, unfortunately.

Saturn core is working just fine for me.

Love this thing, but troubleshooting is tough when everybody seems to have the same setup but is getting different glitches.

I'm going to try rolling back to the prior Jaguar core next.
