Strange error in Dosbox

I can also confirm the speed issue ! Just miles away from before. Some games becomes unplayable. I just tried with No Remorse, even the sound of the videos is interupted or echoed. It is as if you play with lowest framerate. Very strange.

I'm afraid that most games become unplayable, the ones I've tested are not really demanding

I tried some things, also CtrL+F12. There is no changement and some-times he just jump out of the game with Ctrl Keys. Just nice, in Crusader you see now the bullets flying like in MaxPayne.
I was yesterday trying to install Oddworld and didn't arrive, so I will switch back to my Christmas SD.

I just swapped OS, it seems to me that the speed issue is existing already from version 180209 ! So seems to be not a fresh issue. If somebody has still this not yet updated system version, he can perhaps confirm.

@voljega
@lmerckx
Also to note, if it can help. I have not all versions but see a notable increase of size between 2017 and 2018 :

OS 170417 Dosbox size 2977700

OS 180209 Dosbox size 5048136

OS 180330 Dosbox size 5111180

For the moment I copied back the version from 170417 to /usr/bin, and again perfect.

@dragu nice to know ! well maybe @lmerckx will have an idea (and 14 569 notifications )

@voljega
Also something new about the MOUNT C "/usr/share/dosbox" story.
After copy of dosbox 2017 version, this always exist in the actual OS 180330, seems to be a configuration issue.

[lmerckx]

@Dragu @voljega For the moment, not too many notifications !
But sorry for the inconveniences.

The /usr/share/dosbox usage is clearly new to virtual keyboard. The increase of size is strange indeed: new modifications due to b*mp and virtual keyboard modification can't explain this size.

As voljega said before, can be due to a change in compilation directives !?

I will check tonight. But, on my RPI2, I detected no lag ... what are your platforms ?

[Dragu]

@lmerckx
Dont work in the nights !
We have time and also a job to pay for the playing toys. Anyway, for the moment, I am fine with older version.
In my case it is the PI3, but are there differences also in dosbox in PI versions ?
And dont worry.

[voljega]

@lmerckx RPI3 for me too

[Dragu]

@lmerckx
@voljega
Could this be a possible explication for the volume size increase, that the 2018 build is the 64-bit version and not the 32 ?

[lmerckx]

@Dragu @voljega
Back home ...

I've just tested my DosBox RPI2 (updated to 18.03.30) and I confirm: I have no lag problem on games Wolfenstein 3D, Epic Pinball, Ultima 7.
The size of my dosbox is 5046488.

Can you send a support archive ?

Edit: Now, I can reproduce the /usr/share/dosbox bug ! I've never tested without dosbox.bat, in fact.
I look for a correction.
Still no idea for lags.

[lmerckx]

@Dragu Mine is still 32 bits.
Here is the result of the "file dosbox" command, launched from another Linux workstation:
dosbox: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 4.4.0, stripped

[voljega]

@lmerckx doesn't work in recalbox for me : # file dosbox -sh: file: command not found

tried Epic Pinball, lags horribly too :s

@lmerckx do you have a RPI3 ?

[lmerckx]

@voljega Yes, I had to transfered my dosbox exec to another Linux workstation to get "file" command.
I have a RPI2.

Do you also launch games with autoexec or with a dosbox.bat script ?

[lmerckx]

@dragu So, I think I have solved the "/usr/share/dosbox" problem:
When there is no dosbox.bat file in directory, DosBox scan other parameters to find a valid file to execute or directory to mount. When it find the share directory, it stops and go on with it.
It explains why I had no problem. I always use the dosbox.bat file.

So, the solution was to put the initialization of the virtual keyboard before the autoexec startup.

But, I'm curious, how do you configure your autoexec ?
Do you need to specify the mount and exit in it ?
Do you have an example ?

s**t I f you don't have a rpi3, it's not gonna be easy to find the issue ...

Do you also launch games with autoexec or with a dosbox.bat script ?

I always use a dosbox.bat with all necessary instructions in it (mount for instance but no need for exit), I keep no command at all in dosbox.cfg (I always have one too)
If you need, I can give you my dosbox.bat and dosbox.cfg for Epic Pinball

figured as much, but I don't have any linux at home other than my recalbox ...

@lmerckx
In general I have always an dosbox.bat file to start games, and mostly the mount operations I make at the end of dosbox.cfg. But this is just personal choice and no issue.
I found the story with the VK at testing a game. Because, if you start with dosbox.bat and have an error, you will never see it Screen erase instantly.
I for this reason sometimes start a game with no dosbox.bat, for debugging.
Concerning the speed lag, it is in relation important 1/2 as before if not less.
What is surprising that you have with the PI2 no problems, but we with PI3 have.
So, I think solution between both build.

[Dragu]

@lmerckx
I have another idea. Would it be possible to upload somewhere your version of PI2, to test with PI3 ?

[lmerckx]

@Dragu Good idea. The link is here: https://www.proximuscloud.be/web/app/share/invite/HLQ1C8rABR
If it doesn't work with it ... can you send me your configuration file. Perhaps, is it a change I made which still allow to get good performance.
