MSFS2024 compatibility?
-
Any official guidance on this? Just curious. I haven't tried to load the Dukes in 2024 just yet, but I'm very close to trying it ;D
Generally curious about compatibility plans with all the Black Square products - I'm sure it's not easy or quick to fix everything, once again, just generally curious.
-
So a hopefully related question, can I have the Duke installed in both 2020 and 2024, or do I have to choose one or the other? I just opened the install executable and it says it's already installed. I can uninstall it and choose the 2024 community folder I assume, but I'd rather keep it on both for the moment, if possible.

@lilycrose No products from Just Flight can be installed to MSFS 2024 presently via the installers. All of the installers look for MSFS 2020's UserOpt.cfg file. If you don't have MSFS 2020 installed, it outright fails. If you have MSFS 2020, you could try copying the addon's files from the 2020 Community folder to the 2024 Community folder, but I don't know if it would work.

The Pa28 is loaded, but i have a licence error message on the efb

@Derek WOW! Awesome news!! Thank you for pointing this out!
And the Commander 114! Also awesome! When I was about 12 my dad rented a Commander 112 a few times, I always liked that plane. Hugely looking forward to that!
For those wondering about getting the Dukes working for now in FS2024 - Copy your Duke aircraft folders from your FS2020 community folder to the FS2024 community folder. Also, if you want to keep your engine hours and maintenance condition, etc. then find the state.cfg file for each aircraft, and copy them to their respective FS2024 locations as well. I flew the Grand Duke last night and it worked very well in FS2024. There are some animation issues as mentioned elsewhere in this forum by Nick, from what I could find this mainly consisted of the altimeter and altitude preselect window appearing strangely when they move. This is in no way a show-stopper though and I find the aircraft perfectly usable for now.
Awesome times in flight simulation are upon us, and more are soon to come with the new Professional editions of the Analog Overhaul aircraft, the Starship, and the Commander 114! I couldn't be more excited for what is ahead.

I have tried the Turbine Duke, it works 90% but the altitude indicators and baro numbers are wrong. That makes it unplayable for the moment. Also something fishy seems to happen with the amperometers fluctuating more than usual and the cabin thermometer is showing wrong temperature in comparison with the tablet which seems to be the correct one.
-
@sumnersd With both piston and turbine in 2024, it seems what it is actually doing is combining them - Look in the variants and liveries and you will see it's all there, it's just laid out in a really weird way.
I'm sure this will be sorted out when updated for 2024, but it is all still there to access.

Hi, All. I haven't made a comprehensive statement about compatibility since MSFS 2024 released, but I thought I would address these particular issues, since they are all related.
All three of these bugs in MSFS 2024, as unrelated as they may seem, are the result of an incorrectly implemented mathematical operator in the Reverse Polish programming language called "integer divide". In MSFS 2020, the integer divide operator correctly divided two numbers, and then rounded down to the nearest integer. This rounding does not happen in MSFS 2024, resulting in the wrong output.
As you might imagine, this is roughly equivalent to changing how a button on a calculator functions without telling your accountant. This operator is used over 1,000 times across all my aircraft, so replacing it would be no small effort. We have notified Asobo of this issue, but have not heard any acknowledgement of the issue as of this writing.
I hope this explains some of what you are seeing, and might also give you a glimpse into what kind of issues my fellow MSFS developers and I are facing in MSFS 2024.

@Black-Square Having working RPN is 2020 and somehow then breaking parts of it for 2024 was not on my bingo card!
-
@Black-Square Thanks a lot for the update. I really appreciate it. Yes apparently breaking a mathematical calculation means a lot of trouble. I hope Asobo gets back to you as soon as possible.
-
@Black-Square For me everything works fine. The 2 things I saw was the altitude indicator flips a bit weird, and the InHg is showing +1000 3992 instead of 2992 for std pressure.
-
@Avionic I'm not savvy on this, just thinking out loud. Do they not use a standard RPN library? If so, did the library update and change something? It seems strange unless they somehow manually coded their own RPN implementation that such a fundamental operation would change. Not doubting anyone here, just really trying to grasp how it would happen. Edit: From what I can tell, they do have their own implementation. Interestingly, RPN doesn't even seem to have a
flooroperation, the closest isnearwhich rounds up or down on either side of 0.5 to return an int. MS's own SDK showsdivreturning a rounded number though. What an annoying little bug to have to deal with. -
@SwissairMD11 These are all due to the integer division operator, believe it or not.
@LostPilot I actually doubt it's a standard library, or at least one anyone would recognize, because I believe the MSFS RPN implementation has been virtually unchanged since 1995. If I had to guess, I believe this change was probably the result of experiments with compiled RPN, which is a new option for developers seeking a little performance boost to their animation code. You can imagine how this might entail porting the RPN interpreter to a new language in the process. Hopefully you can all understand how this affects us developers, and why I'm not rushing to update my code in twelve aircraft across two simulators for such a fundamental oversight.

Very understandable. Having to update all of those uses of the operation when they'll likely fix it would be a waste of valuable time. Good luck!
