I appreciate everything you have done with the JagGD and getting CD support working as best as possible with the hardware limitations. Has there been any thought given to an upgraded version of the JagGD in the future that would be better able to handle CD support to hopefully eliminate some of the finnicky issues people are experiencing?

An 8GB no name class 2 and a 32GB SanDisk ultra … If I format default they both have 32KB sectors. The 8GB formatted 4KB was bad, at 8KB was better but WTR left in demo loop would eventually lock up. The 32GB on my PC via usb3 reader reads at 90MB/s and writes at 60MB/s … I always have to have 2 copies of the whole cd folder (guess the lower sector are “slower”) but I have not been able to successfully pause Hungary (arcade race after USA) and return to main menu and play again … it randomly locks somewhere, tried with 8KB/16KB/32KB. Are you using the SD in 4bit mode or strictly serial? 17 hours ago, Zerosquare said: Interestingly enough, some SD cards documentation's do point out that minimum throughput is only guaranteed in 4-bit mode, not in SPI mode. 6 hours ago, SainT said: No clue.

SainT Posted May 14 Author Share Posted May 14 Throughput isn't an issue with regard to hanging issues in general, mostly it's because the Jag is missing an interrupt generated by the GD. I'm also getting some spurious data coming from the Jag during WTR which is what the hanging is you're seeing with that game. I'm debugging that at the moment, but with no improvement yet. 2 Quote Link to comment Share on other sites More sharing options...

Hey SainT! Thanks for you're hard work on JagGD! All my CD games work. I had a question, is it possible to extract the memory track files from the SD card? I wasn't quite sure where it was getting saved to. BTW Folks if you're having issues running a game, chances are also the game rip is bad. Look for REDUMP versions. I downloaded redump and converted to JCD and they all worked perfectly including WTC and VidGrid. Quote Link to comment Share on other sites More sharing options...

Look for REDUMP versions. I downloaded redump and converted to JCD and they all worked perfectly including WTC and VidGrid. Good idea to use certified sources but they may not solve all the problems, in my case I can start WTR and play arcade on the US track then go to Hungary and play but if I pause in Hungary and via option exit the game eventually it gets stuck before I can chose to play again, it’s fine if instead I exit in the US race (well I did it once and it worked vs Hungary that never did for me) … the spot where it blocks is not always the same so not sure about the bad rip theory. This is an image I dumped and jcd converted myself from an Etsy bought WTR burn that works just fine on the real JagCD exit and all … so there’s some instability … Vidgrid on game drive has been great since the last fw and I quickly tried dragon’s lair, space ace and braindead 13 and I saw no issues at least in the first 3 or 4 scenes of each as well as primal rage first 3 fights.

Sure, there's a hidden folder on the root of the memory card called "MTRACK". This contains all the memory track save data. 1 Quote Link to comment Share on other sites More sharing options...

WTR is a pain, I know it has issues. There does appear to be an issue with one of the CD tracks missing data markers, but I don't *think* this is actually causing any issues.

SainT Posted May 15 Author Share Posted May 15 Ok, a new firmware update has been released. I've fixed one of the issues I was seeing with WTR which was causing instability, it still dies if left on soak, but I think it's improved. Likewise I've fixed some other potential issues, but am not sure how much things have improved due to this. Issues with memory track on homebrew (notably Yopaz and Alice) have been fixed. These were actually due to junk being passed instead of a filename, so I've accommodated for this by using "NONAME" where junk is passed. Save on Robinsons Requiem is still misbehaving and I don't understand why. 8 Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted May 15 Share Posted May 15 Is there a direct link to download the firmware or just the qr scanner option Quote Link to comment Share on other sites More sharing options...
SainT Posted May 15 Author Share Posted May 15 If you have a cart which has the QR update system, you have to use it. There's about 200-ish JagGD carts in existence which don't have it, so of the active user base it's very few. I don't like posting the link for the older carts publicly as everyone with the new carts then downloads it and asks why it doesn't work. 1 Quote Link to comment Share on other sites More sharing options...

bjkock Posted May 15 Share Posted May 15 Unfortunately the 1.14 was a step backwards for me. After upgrading I tested WTR, Vid Grid and Robinsons Requiem and they all hanged and wouldn’t start, but they work almost every time with 1.13. Decided to reformat the SD-card and copy them back again, but this didn´t help, they still hang at different places every time I try to start them. Downgraded back to 1.13 and now they work as they did before again and are playable most of the time. Anyone else experienced this when upgrading to 1.14?

SainT Posted May 15 Author Share Posted May 15 (edited) Interesting. Stick with 1.13 then! It's definitely been no worse on my Jag, and generally a bit better. Unfortunately there's little I can do to figure out why, either. Edited May 15 by SainT Quote Link to comment Share on other sites More sharing options...

Else I will stick with 1.13 for now, even if I really looked forward to be able to save on Yopaz and Alice 🙂 Quote Link to comment Share on other sites More sharing options...
SainT Posted May 15 Author Share Posted May 15 There’s one thing it might be. See how you get on, I may do a private update for you to test with just one change. At least it would help rule things out. Is ROM loading affected? Quote Link to comment Share on other sites More sharing options...
phoenixdownita Posted May 15 Share Posted May 15 (edited) Went to 1.14 but WTR (the only one I tried) would not even start, never managed to get to the start screen. Reverted back to 1.13 for now, messaged Saint already about it. Note that the QR code changes at every flash, and it seems you need new .upd/.ovr files afaict (I used to keep the old upd files but they are useless it appears) ... which slows down the cycle, anyhow I am back in working state.

SainT Posted May 15 Author Share Posted May 15 Update files are one shot use, so don’t keep them. Make sure after update that the versions numbers are correct when you hit 0 on the menu. There’s no reason they shouldn’t be, but it sounds like some people’s didn’t update. If you have any issues with the update then get another QR update link and click the top link on the versions list. This will download a firmware.ovr file. Update using this, it forces everything to update rather than just the bits that changed. Quote Link to comment Share on other sites More sharing options...

SainT Posted May 15 Author Share Posted May 15 (edited) There’s some question as to whether it’s updating everything. Check the versions by hitting 0 on the menu and see what you get. If the menu version is wrong, rename the .upd to .ovr and see if that works. If it’s still doing nothing, try copying it to a blank memory card and trying again.

The info states you should get 1.14/1.10/1.10/1.06 but my menu stayed at 1.09 (from the 1.13 update).
