In any case, JJ2+ continues to support Windows XP, despite the dangers of people using it in any other context.

Sure, it ran Windows 7 with Aero (nvidia geforce fx 5200), but as explained from the specs above, not a really good idea. The latest Ubuntu version that supported NVIDIA-173 drivers for my graphics card was 14.04, and I liked performance on my games, so yeah, I had to improvise on XP during all those years. Like how Teeworlds 0.7's binary downloads didn't work on Windows XP so I compiled it from source myself.

Nowadays I have two laptops with Windows 7 and Windows 10 on them (I main the former), but I had to go through quite a lot while I was on that old rig.

I'm sure you have your reasons, but the fact remains that you are using an operating system, connected to the internet (I assume), which is not equipped to deal with the attack surface exposed by doing so. This is even more true now than when I wrote that previous post. Perhaps you have weighed the pros and the cons, and made sure there is no personal data at all on the PC, et cetera.

But from experience I feel it's safe to say that many other people who played JJ2 on XP, three years ago at least, had not carefully considered the disadvantages of doing so, and simply did so because 'it still works' or because they did not want to go through the hassle of upgrading or switching. That remains a bad idea, and if anyone reading this is still using XP for that reason, I again strongly urge them to upgrade.

The same goes for Windows 7 users.

Hello,

Hey, I’m sure that people still using Windows XP or 7 are very old-school people who never have any simple consideration for recent opinions or facts.

I've had much better luck running JJ2+ with recent versions of Wine than anything Windows ever offered since 8 came along.

Besides odd micro stutters, the problem of losing connection in-game after switching from fullscreen to windowed kept persisting all the way to the latest version of Windows 10 (build 2004). Alberto's ddraw.dll substitute at least made fullscreen mode manageable.

Hi everyone again! It's been a while... I'm happy to continues the Windows XP support of the Plus. Because the my laptop is weak to Windows 7 or above.

New release (5.7)
Download from J2O | Download from ModDB | Download from GOG (or use GOG Galaxy)

The full list of changes can be found over here.

If you are having trouble with the latest version, report the problem in this thread! General discussion of JJ2+ is fine in this thread too. For less urgent bug reports or suggestions, please visit our dedicated issue tracker instead.

Yay!

Related to the anti-cheating updates, here's a long article I wrote with some ruminations on JJ2+'s (lack of) anti-cheating features if that's something you're interested in.

partayyyy its finally betterified i love it!

Thank you JJ2+ developers for the continued support and the awesome new features. Your work directly invigorates the community. My favourite in this update is the "rescalable window" option.

I am sorry to potentially sow distrust here, but my Windows 10 antivirus tags the "plus_install.exe" downloaded from Violet CLM's link ("Download from J2O") as a virus, more specifically "Trojan:Win32/Wacatac.D3!ml". Respectfully asking, can you offer an explanation for this alert?

The same issue has been brought up in another thread here (note that the thread starter mentions 3 other pieces of antivirus software that don't detect anything).

It's hard to guess what Windows Defender has an issue with precisely, but it's probably the usual: it's a rarely downloaded file from an unknown source, it's new and Defender hasn't seen it before, and it modifies an exe file on your computer to run its own code. To antivirus software, that sounds scary. Perhaps it also detects some specific byte pattern that just happened to occur naturally by chance within the file.

It's always hard to know, because antivirus software relies on heuristics. It tries to be usually right but there's just no way to reliably tell malware apart from safe software, and antiviruses are generally closed-source so we can't just check with them and figure out which of the things we did triggered an alert (which makes perfect sense, because if we could, so could malware developers).

Just out of interest, would that mean that an antivirus eventually stops detecting it because some magic download number has been reached?

Not directly. I think Google Chrome takes download count directly into account and warns you if an executable file is rarely downloaded, but Chrome is a web browser. An actual antivirus would probably have to go further than that. I know Avast has the thing where if it suspects a file is dangerous, it suggests that you send it for further analysis. Who knows what that means; probably still heuristics but ones that take so long to run that people wouldn't want to do it on their own personal computers, so they have servers do it.

Theoretically, a large number of downloads (by unique people all running the same antivirus software) could lead to the software coming to conclusion that "OK, a lot of people are running this file instead of just 5, maybe we should actually perform deeper analysis on it," which could effectively mean that a magic threshold has been reached and now the file is suddenly no longer considered malware, but internally it would be because it has qualified for further analysis which found it safe. This makes sense in theory - if the more accurate analysis is more computationally expensive and performed on company servers, the company may want to avoid using it for every report, and the number of users it affects is a decent metric for estimating how urgent that is. Does any antivirus software actually employ this strategy? I have no clue. They're black boxes as far as I know.

Thank you Seren for your thorough reply.

Had the same issue for some reason

What version of JJ2+ are you running? That bug was fixed in 4.3.

"If one of the splash screens shown when starting up the game says "LK Avalon," that is additionally not a compatible version of the game."
Mine says "LK AVALON" but mine is compatible, so wdym

ok thats just incorect
i have jj2+ running on a virsion of jj2+ with LK AVALON
so pls dont lie to anyone

Have fun using our mod! I'd provide some tips but apparently you already know how our software works better than those of us who've been developing it for the last 13 years.

Same here, it's working very neat with my LK AVALON version. Not sure what Seren wants to say.

I don't know what shady version of Jazz Jackrabbit 2 you've got, but the mod doesn't and won't ever work on the official LK Avalon version.

Hi there, this is my first post on these forums (despite being a JJ fan since... forever). I managed to patch my copy of the game from 1.20 to 1.23, and download the Plus version. I can't wait to test all of the extra content!
