We can take this to PM or the FujiNet forum - clearly I'm pissing off some folks in this thread by stress-testing the game on too many obscure or unusual hardware configurations. But I will also note that the file versions have only caused me problems on my NTSC systems. My PAL 1088XLD will run the "bugfix" full-game ATRs for hours from my LAN, not the local SD card.

The issue lies squarely with the Fujinet device right? Could be. On the other hand, in ~11 months of using FujiNet devices across all my A8 machines very heavily, this is literally the *only* title I've run into that has any issues with running indefinitely from my LAN's TNFS server - and that includes quite literally hundreds of ATR, ATX, CAS and XEX files both vintage and modern. We already know the core PoP game code runs stably when formatted to run as a cartridge image on real hardware; it's only when running from a LAN TNFS server on NTSC hardware via FujiNet that I've had problems. Does that point a finger at XBios for exposing an edge case in FujiNet or does it point a finger at XBios for being an edge case in terms of file systems? You be the judge of that one. I point this out simply because FujiNet has rapidly become the single best, most capable and flexible SIO device available and is being used by a LOT of hobbyists. If there are compatibility issues with a prominent and dare I say maybe even important new piece of software for the A8 platform, it's best to hammer out the compatibility edge cases no matter if they're on the game's file system side, the FujiNet firmware side, or a combination of both. That said, and in the interest of providing feedback to both @mozzwald and @rensoup, I've had the June 18 "bugfix" full-game ATR running from my FujiNet's local SD card on my 576NUC+ for over an hour when previously I had difficulty even getting it to load successfully on this hardware from my LAN server, or getting the later optimized demo versions to run for very long. 1 Quote Link to comment https://forums.atariage.com/topic/298914-unicorns-season-prince-of-persia-for-the-a8/page/78/#findComment-4853287 Share on other sites More sharing options...

Hopefully the cause of this can be worked out. For everyone's sanity, let's all say a prayer at the alter of Fuji, that this is not a machine dependent timing case, like many of the Phi02 issues, or god forbid - U1MB + Rapidus in the same room.

I would almost suggest trying the PoP_DD_20210610.rar version... but there is also an uninitialized display list issue which can cause it to crash at boot with certain configs. The bugfix version only dodges potential issues by trying to avoid retry errors... the PoP_DD_20210610.rar has tons of retry errors but loads with real drives (very slowly). So if you want to expose potential driver bugs easily, this might be the version to use. Alternatively I could make another test build with the fast mouse drawn many times to force retry errors.

tschak909 Posted June 29, 2021 Share Posted June 29, 2021 (edited) Holy f*** this blew up! There seems to be a fundamental misunderstanding on how network performance impacts timing on FujiNet: Basically, we don't send a complete back, until we have the sector we want in question. This can take a variable amount of time, and in order to keep performance up, we ask for approximately 512 bytes of data from the TNFS server. Again, we do not send the complete until we have the sector we're asking for in fujinet memory. This is completely within the SIO spec, as SIOV will wait until DTIMLO has expired before re-attempting the command. one of two things can be done: (1) an ATX format disk can be made, which will ensure that timing is correct, because we cache that entire disk into the FujiNet memory. (2) a read only fetch mode can be implemented from our side, again, to ensure that timing is correct. I am a bit worried that we are assuming things like best effort sector timing in our loaders. -Thom Edited June 29, 2021 by tschak909 3 Quote Link to comment https://forums.atariage.com/topic/298914-unicorns-season-prince-of-persia-for-the-a8/page/78/#findComment-4853610 Share on other sites More sharing options...

When I posted the photo a couple pages earlier, I was well into the 3 hours of gameplay, I had just let it run idle at that moment because I had to do some other stuff shortly after.

Who will do the 48hour burn-in, ermm, looping test of this demo ATR ? P.S.: Afaik, the Speedy 1050 enhancement always caches Boot and DIR sectors of DOS 2.x disks. 1 Quote Link to comment https://forums.atariage.com/topic/298914-unicorns-season-prince-of-persia-for-the-a8/page/78/#findComment-4853907 Share on other sites More sharing options...

Nope - countless people used to run BBSes back in the day, 24/7 for years. 1 1 Quote Link to comment https://forums.atariage.com/topic/298914-unicorns-season-prince-of-persia-for-the-a8/page/78/#findComment-4853960 Share on other sites More sharing options...

I'd rather start a Kickstarter campaign to surgically remove that stick from your ass (and maybe even your head while the surgeons are in there). 1 4 Quote Link to comment https://forums.atariage.com/topic/298914-unicorns-season-prince-of-persia-for-the-a8/page/78/#findComment-4853961 Share on other sites More sharing options...

I had played for nearly 3 hours in a row, died a ridiculous () amount of times between the first few levels I was able to play. Then, I left to cook dinner a bit later that day, and kept the Atari 800xl + AVGCART running the game, which eventually went back to the demo + title screen loop, and that alone ran for the entire evening until I came back in my office and powered it off. Everything was still running perfectly fine. In total, the game ran for nearly 6 hours without a single problem. In fact, I couldn't even tell if there was any bug present during the entire time the machine was powered on. When I posted the photo a couple pages earlier, I was well into the 3 hours of gameplay, I had just let it run idle at that moment because I had to do some other stuff shortly after. This was the day before the "bug fixed mouse animation" version if I am not mistaken too. I can verify this as well. I've left the .CAR image running for days on my Incognito 800 with the Ultimate Cart. Mostly demo mode, but I've taken a few stabs at actually playing the game. I'm not very good at it yet... having a hard time with the controls, figuring out the different moves. Is there an unofficial manual for this somewhere?
