Mupen64plus-GlideN64 Control help

@Drdave79 Are you really sure you're running the libretro core for N64 ?
You can delete the /opt/retropie/configs/all/n64/retroarch.cfg file and then re-install the lr-mupen64plus-next package, which will generate the config file.

Drdave79

@mitu Alright, progress! Thank you @mitu. That allowed me to access the Retroarch menu. However, this emulator is running really slow and choppy with the default graphical options. Do you have any recommended settings for this on an non-overlocked Pi? When I was using mpuen64plus-GLideN64, the gameplay was pretty smooth, though graphics suffered a bit.

Since some games use the N64 joystick and some use the dpad for movement, there's got to be another way to change this per game besides editing the .ini file manually every time you want to play each game?

Could you do it with the --datadir (and/or --configdir) flags? If you're willing to experiment a little, try this:

Put the config back to how it was so the joystick is read as the analog axes.
In /opt/retropie/configs/n64/, make a sub-directory called dpad. Copy the following into this dpad dir:

font.ttf
*.conf
*.ini

Now edit the dpad/InputAutoConfig.ini file with your D-pad fix from before.

Now you have two config dirs: n64 with the standard analog control, and n64/dpad with D-pad control instead.

Next, edit the file /opt/retropie/configs/n64/emulators.cfg. We will add another entry to it, to use this new config dir. Find the line for GLideN64:

mupen64plus-GLideN64 = "/opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh mupen64plus-video-GLideN64 %ROM% %XRES%x%YRES% 0 --set Video-GLideN64[UseNativeResolutionFactor]\=1"

Copy that, change the name to mupen64plus-GLideN64-dpad and add the --datadir (path) param to the command:

mupen64plus-GLideN64-dpad = "/opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh mupen64plus-video-GLideN64 %ROM% %XRES%x%YRES% 0 --set Video-GLideN64[UseNativeResolutionFactor]\=1 --datadir /opt/retropie/configs/n64/dpad"

Launch the game; press a button to open runcommand launch menu, choose "select the emulator for ROM" and select mupen64plus-GLideN64-dpad.

The only reason I can think why this shouldn't work is the mupen64plus.sh launch script already sets a --datadir param, so this will have it in there twice. I'm hoping it will just honor the last one used, but it might instead use the first one, or just break.

If that's the case, you could probably still do it, just a little different.

Still do everything up to making the "dpad" entry in emulators.cfg, but don't add the --datadir param to the command there; instead, just change the name and change the specified launch script file from mupen64plus.sh to mupen64plus-dpad.sh:

mupen64plus-GLideN64-dpad = "/opt/retropie/emulators/mupen64plus/bin/mupen64plus-dpad.sh mupen64plus-video-GLideN64 %ROM% %XRES%x%YRES% 0 --set Video-GLideN64[UseNativeResolutionFactor]\=1"

Now go into the binaries dir:

cd /opt/retropie/emulators/mupen64plus/bin

Copy the launch script. You have to use sudo to make any changes in this root directory:

sudo cp mupen64plus.sh mupen64plus-dpad.sh

Edit this new copy:

sudo nano mupen64plus-dpad.sh

Navigate to line 447:

SDL_AUDIODRIVER=${SDL_AUDIODRIVER} SDL_VIDEO_RPI_SCALE_MODE=${SDL_VIDEO_RPI_SCALE_MODE} "$rootdir/emulators/mupen64plus/bin/mupen64plus" --noosd $PARAMS ${WINDOW_MODE} --rsp ${RSP_PLUGIN}.so --gfx ${VIDEO_PLUGIN}.so --audio ${AUDIO_PLUGIN}.so --configdir "$configdir/n64" --datadir "$configdir/n64" "$ROM"

Change the --datadir parameter from "$configdir/n64" to "$configdir/n64/dpad"

SDL_AUDIODRIVER=${SDL_AUDIODRIVER} SDL_VIDEO_RPI_SCALE_MODE=${SDL_VIDEO_RPI_SCALE_MODE} "$rootdir/emulators/mupen64plus/bin/mupen64plus" --noosd $PARAMS ${WINDOW_MODE} --rsp ${RSP_PLUGIN}.so --gfx ${VIDEO_PLUGIN}.so --audio ${AUDIO_PLUGIN}.so --configdir "$configdir/n64" --datadir "$configdir/n64/dpad" "$ROM"

That should be it. Again, you would launch the game and select the "dpad" variant in the emulators menu, for each game that requires D-pad control.

@sleve_mcdichael wow, that's a lot of information. Yes, let me give this a go and see how it goes. Need to make a backup of my build first though :)

That being said, if I could find settings that made lr-mupen64plus-next run smoother, it'd be a great solution as well. Going to spend sometime looking into this as well.

lr-mupen64plus-next

@mitu @sleve_mcdichael Upon further testing, lr-mupen64plus-next run pretty slow. lr-mupen64plus without the next actually runs pretty well. Much better than the "next" version. And since they're lib cores, I can edit the controls directly in the menu!

I think with N64, it's really going to come down to the individual title. Some will work just fine in the default lr--next, but some others that are unplayable in that one, may still work in one of the others.

I think the thing with the "next"/"no next" versions is that "next" is still actively developed, while "no next" is abandoned. If it works, it works, but don't expect any updates (which is not necessarily a bad thing, as long as it does work.)

Drdave79

@sleve_mcdichael That's interesting. I tested around 10 titles and almost every one worked smooth with no next. I had to use mupen64-plus-GlideN64 for Star Wars Rogue Squadron for smooth gameplay and control, but that was the only exception. Almost seems like the "next" team is going in the wrong direction.

No, it's not. The direction is to achieve accurancy and better emulation of the original N64, not speed. That's not specific to N64 emulation only.

Drdave79

@mitu I didn't mean to offend anyone by my statement. I know everyone involved in these projects work very hard whether paid or volunteers. It was just an observation that the non-next version, which apparently is no longer supported seems to work better. At least, for my testing.

No offence taken, and it's normal that is runs better, since the performance requirements are lower. This is why it's still available in RetroPie.
