@jamrom2 You'll have to wait for the install script to be updated in order to get the default shaders included and get past this error. Or you can create the shaders' folder as $HOME/.config/dosbox/glshaders and copy the files from here in that folder.

EDIT: I found it funny that specifying glshader = none in the configuration file would actually make dosbox to load a shader from none.glsl file.

jamrom2

@mitu ok, I'll give that a try. I would think without a shader specified it should just load without it, or default to none and skip it.

Will the shaders even work with a Pi3? Never did before.

Thanks!

They don't seem to work, but that may be because the detection in dosbox-staging for the GL driver seems to fail on a Pi3. I wonder why that is...

jamrom2

@mitu That worked. I added the shader folder.

Not sure about using the shaders though. I set mine to "none" until it's confirmed they'll work on a Pi3.

Hi,

DOSBox Staging latest update has now been merged in Retropie (0.79.1). It contains bugfixes (mostly SoundBlaster related) as well as a new extra: mapping files for Xbox controllers. This allows users to enjoy DOS games with only their controllers. Plug your controller, point your conf to the proper mapperfile and you're good to go. Select+Start combo works the same as RetroArch: it closes Staging. The doc is there.

Shaders are there as well yet they will work only when an opengl* output is selected (RPi4 only).

I'd recommend users to upgrade to that version from the Retropie-Setup script. Staging has now been moved under the optional section.

After you've upgraded the DOSBox Staging binary it's wise to update your dosbox-staging.conf as well. Do so by typing in the following command:

C:\>config -wc

Thanks to the DOSBox and Staging community. Any feedback appreciated as well as any participation. And of course thanks a lot to mitu and buzz for excellent feedback, thorough testing and advices.

Leisure Suit Larry 6 and 7.
On the oc they run fine with no modifications. However, the dosbox on the pie is asking for a cd. Is there some batch file with mounted drive I need to create? Does the pie being drive Z mess things up as it isn’t drive C?

Specific questions I have , I know. If you need the files...to try to simulate issue....

nemo93

@duglor thanks for reporting. Not sure to understand your exact issue (what's an oc?). The Leisure Suit Larry's are all working fine on DOSBox Staging (DOSBox too I suppose) even if I prefer to go with ScummVM for those. You have to mount your CD image then go through the install process prior running the game.

There are quite a lot of docs available online covering that topic. I can point you to DOSBox Staging wiki which contains some pointers for new users. The official DOSBox wiki is also a great source of information. Please read those carefully.

The Z: drive is special as it contains necessary files to run the DOS console. It won't mess up with anything.

DOSBox Staging 0.80.0 has landed a couple of days ago. Thanks as usual @mitu for ensuring Retropie's script has been updated accordingly (thanks!).

You can read the changelog but in a nutshell:

ReelMagic DOS games are now playable thanks to the efforts of Jon Dennis, Chris Guthrie, and Joseph Whittaker, with testing and feedback from Vogons users Uka, DonutKing, and Vetz
Mouse emulation has been improved and now supports up to six independent mice, enabling split-screen play in games like The Settlers and The Settlers II
More settings, including video, audio, and MIXER effects, can now be changed on the fly

Enjoy!

DOSBox Staging 0.80.1 has been released with the usual bugfixes. Yet the biggest news is: new website for this fork. It just landed hence few things will be tweaked in the coming days. An overhaul of the doc should come as well.

I still consider it the best 'all rounder' fork available. Really nice performance (ie. Doom runs at 'full speed' on stock Pi4), same config file as Dosbox 'SVN' (eg. easy to make the switch) and clearly the best fork regarding audio given the many soundcards supported/emulated with great accuracy. Not as comfortable as a libretro 'core' (Pure, Core, etc) for sure yet it's worth a try. I'd like to mention also Dosbox-X which is fantastic fork as well for those wiling plenty of options.

@BuZz @mitu not sure it's the best place to ask yet would you be ok for Retropie to appear under the Downloads/Linux section of that new site? (Frankly I'd love to). We collectively spent a tremendous amount of time to ensure it works great on RPi devices and integrate well in your distro. I won't push any more PR if you agree :-)

Thanks.

@nemo93 I would love to include this on my RetroPie extras GitHub if I can.

I have not gotten around to messing around with it yet but I'm all for adding more things to it

Sure, why not ?

Thanks for all the testing, much appreciated ! PRs shouldn't be needed except on build issues (like the updates for 0.80 due to the meson upgrade), since the scriptmodule automatically installs the latest stable release (as opposed to Amiberry, where the version is pinned).

nemo93

@mitu @BuZz appreciated. A short desc will be added soon on site. Thanks for your patience and also all testing/checking/packaging (you certainly look after way more softs/emus than me).

@ExarKunIv not sure what you mean? DOSbox Staging is part of Retropie (Optional Packages) already. Let me know what I'm missing here please.

ExarKunIv

@nemo93 my bad, i have not updated my script in a long time, so nevermind then

@nemo93 Hi, I just read the whole MT32 Wikipedia list drama. As I don't know how to better contact you I'll do it here: the list was cloned to the Vogons Wiki, so you might want to link to that from the Dosbox Staging Wiki.
I often used the list and really still don't understand why it was removed from WP.

nemo93

@ecto thanks for that. I edited wiki with link to Vogons. I saw it yesterday so your timing is perfect. This decision by Wikipedia is really baffling to say the least.

@nemo93 hello there

Is there a guide to install Windows 98 / ME in the Raspberry Pi 4???

I followed some guides before using dosbian but it crashes to the desktop on first boot with explorer crash and other misc errors

The only working dosbox was the dosbox-X

But the performance there was very very slow

I saw videos of dosbox-svn and dosbox-ece running very good Windows 98 but couldn't install them successfully i got the errors described above
I must do something wrong

Thanks

nemo93

@retropi19 as far as I know there's none. The reason is simple: DOSBox doesn't support officially anything after Windows 3.11. You're right DOSBox-X is the one to look after to achieve that task yet as you said performance-wise it won't be great (X does have a fine wiki with plenty of guides one of those is dedicated to Win98).

For Staging the actual stance is similar to DOSBox 'SVN': no official support (as stated on https://github.com/dosbox-staging/dosbox-staging/wiki/Windows-9x). Some users are really committed to get it to work but they're using much more powerful systems than RPi's.

Don't set your expectations too high for the time being. Perhaps you could check box86/Wine instead? There's already a topic in that forum.

If anyone knows a better way feel free to share in order to keep me honest. Thanks.

Hello all, apologies if this is a newbie question --- I'm revisiting some of the custom DosBox mappings I have for a few games and for my RetroFlag GPi case (the original on a RPi Zero 2W) the axis mapping is 4/5 not 0/1.

I must be missing something because I thought the syntax was axis id and 0 if -, versus 1 if +.

So I thought

key_up "key 82" "stick_0 axis 1 0"
key_left "key 80" "stick_0 axis 0 0"
key_down "key 81" "stick_0 axis 1 1"
key_right "key 79" "stick_0 axis 0 1"

Would translate to

key_up "key 82" "stick_0 axis 5 0"
key_left "key 80" "stick_0 axis 4 0"
key_down "key 81" "stick_0 axis 5 1"
key_right "key 79" "stick_0 axis 4 1"

But that's not working. Normally I'd just fire up the keymapper to test but for this device I don't have a pointing device to drive it.

Please help!

nemo93

@ParadoxGBB let me point you first to that wiki entry. What kind of pad/controller do you rely on please?

ParadoxGBB

@nemo93 Yup, that wiki doesn't go into the specific syntax of the axis entries, or at least I'm not seeing it.

The controller I'm targeting here is the one built into the case itself, it is similar in form factor to the original gameboy. I've mapped out all the buttons but not sure how to translate the dPad.
