lr-dosbox, how use a general config in orde to speed up execution

mth75

Hi all,

I'm experimenting with both lr-dosbox and the "normal" dosbox package. On my rpi 3b+ (updated to all the lastest packages) I find that the normal dosbox crashes on the F1/Keymapper (crashes in such an order I have to pull the power plug) while lr-dosbox is slow (out of the box).

My question is, how can configure lr-dosbox (in ordere to configure the [sdl] options)?

In dosbox I use the dosbox-svn.conf file for a general configuration. In the lr-dosbox I couldn't find such a file ... while using the retroarch-core-options only seem to provide a subset of configuration options in comparison with the dosbox-svn.conf file.

Best regards!

Marc

@mth75 What exactly do you mean launching the keymapper crashes DOSBox? What does the keymapper look like? If the boxes and text are blue like this, then you should launch DOSBox with dispmanx enabled, which you can setup in the Configuration / tools menu of the setup script.

I never used the keymapper on the Pi version of DOSBox. Instead, I set up and tested each DOS game on the desktop version of DOSBox first. While doing so, I would use the keymapper. I would then copy over the game files and mapper files to my Pi. Though now, I tend to create the mapper files manually.

For lr-dosbox, you can launch games using a .conf file in which you can place the DOS commands to launch the game as well as any setting from the DOSBox config file, dosbox-SVN.conf. You can do this for the standalone version of DOSBox too.

You should never pull the power plug as it can lead to SD card corruption. If your Pi is connected to the network, then you can use SSH to reboot - the command sudo reboot will do the job. Alternatively, if you have an Android smartphone, you can use an app like Raspi Check.

Thx for your reply Dudleydes.

The system shows a blue screen and freezes completely and can't be shutdown (even remotely). Of course i'm aware of SD card corruption :-) ... it happened just before I made my first back up image. In the meantime I've read that this is a known bug.

Using a conf file per game has the advantage that scraping is possible.

Indeed, i'm aware. I reverted to the experimental dosbox_sdl2 package, runs perfectly. Although i've to quit manually with an exit command on the dos prompt.

@mth75 The blue keymapper screen shouldn't be frozen. It's just that it's difficult to see the mouse cursor (it can just about be seen in the top left corner in this image) unless the brightness is turned up .

Have you tried launching DOSBox with dispmanx enabled and then launching the keymapper?

What do you mean by

can't be shutdown (even remotely)

DOSBox can't be shutdown or the Pi? I have never had an issue using SSH to reboot from the blue keymapper screen.

To exit DOSBox automatically after quitting a game, you can add the command exit as the last command in the [autoexec] section of your conf file.

The whole system (the normal Dosbox package that is) freezes when trying to open the key mapper. Hence a remote shutdown isn't possible. Somewhere I read that this is a known bug.

Yes, totally forgot! Thx!
