@mitu Yeah, I figured it shouldn't have any effect on audio output. The only audio settings I've changed are in /usr/share/alsa/alsa.conf, where 2 is the number of my audio device:

defaults.ctl.card = 2 defaults.pcm.card = 2

@barbudreadmon oh I follow you now. And that's nice to know about the mame keys. That will be useful to me shortly.

Thank you again for helping me understand all of this.

Luckily in this instance, it was user error.

@mitu great thank you it works :)

@eberhab

Ok,
Good find !

@mitu That's it! That was the solution.

Thanks for helping me out. I'd probably never had guessed that. Thanks a lot!

@wawa Assuming the core's source code is hosted on Github, all you'd need to is make a scriptmodule for it, test it to verify it works, and then submit a pull request to the RetroPie-Setup Github repo.

Thankfully, for libretro cores, there are tons of scriptmodules you can use as a reference to write your own; just take a peek in /home/pi/RetroPie-Setup/scriptmodules/. Assuming you know how to write a .sh file that complies with this style guide (and know how to use Github's pull requests), you should be good to go!

@Protocultor said in New scriptmodule for Master System & Game Gear emulator:

Seeing that I've created a second scriptmodule for another Sega 8 bit core, this time I've opted to do a PR for both:
https://github.com/RetroPie/RetroPie-Setup/pull/3170
I hope this one has a future.

Just in case, Gearsystem, the new core, is not better than SMSPlus-GX, but has SG-1000 support.

SMSPlus-GX looks interesting. Thank you for submitting a PR and keep submitting them and don't be discouraged! 😊

For ChannelF libretro core

Working well for me, except on my pocket console (don't like teensyduino with START button)

I can get to the core options using select&start anyway. (Those two are the only buttons that function) I couldn't find the option at first (because one would think that would be in the Controls menu...) but I found it and it now lets the joysticks work, at least. I have to check the buttons on a different game (because pacman has no buttons). I'll set it at the Core level once I test it out. So far, so good.

EDIT: I think it's working properly at this point. Thanks!

@BJRetro no it ran very poorly on my overclocked pi 3b+ last time I tried it. Maybe some older 2d only games might be ok but the few games I tested were very choppy.

@BuZz
Is it possible to add this core to retropie?
https://github.com/stella-emu/stella/tree/master/src/libretro

It's the upstream stella, but I am not sure how to compile it as libretro core... so I do not know I it's compatible with arm architecture.

Hello all, a quick PSA :)

The lr-mupen64plus-next core got updated some days ago and now is defaulting to 640x480 resolution for new installs. This resolution is a bit taxing for humble devices such as the RPI3 or less, so is strongly recommended that you set the rendering resolution to 320x240 (as it was previously the default) for these devices. Perhaps this is not necessary for RPI4, you have to see for yourself.

This can be done after starting any game and going to the core options menu in RetroArch.

It is important to note that this is not a RetroPie change, but an upstream change. We decided to not change the upstream defaults therefore it is your responsability to change this setting for your own setup.

If you had the core previously installed, the new defaults will not apply because you already have the previous resolution set in your core options.

@mitu Thank you so much. You were right. I had mixed line endings from editing it on Windows. It install and runs. It runs really slow on the Pi, but I'm sure I'll figure that out.

@hhromic I have changed my script module to include the sources_superflappybirdsfunction as you have suggested. I'll also set it up under the ports folder.

I am hoping to get the game added to zerojay/RetroPie-Extra repo, once it is working well.

THANKS MAN! I WANTED IT FOR MANY TIME!

Hi Mitu,

Thank you for all the help, but i gave in last night after spending another couple hours install --reinstalling everything i could think of. That particular package wasnt in my list, but good to know in the future.

Obviously i did something that caused this and it seems to be related to the nvidia driver used so theres a pretty good chance ill run into this again at some point since all my workstations (including at work) run linux with some that do have nvidia cards.

I wish i knew exactly how i did it though...I even went as far as setting up another workstation retracing my steps exactly as i thought i did at home and could not reproduce the issue.
I believe i also had a couple ports open running to the machine for when it ran windows, but i dont think theyre open by default in ubuntu (666, 3389) so maybe, but maybe not...

Anyhow thank you for much for the help!

@John_RM_70 said in New Sega Saturn libretro core : Kronos:

The odroid xu4 has a awesome Sega Saturn emulator, at early stages, but it's looking great for a single board computer.

@barbudreadmon said in New Sega Saturn libretro core : Kronos:

I'm not sure support for boards like the odroid xu4 is likely, because i know a few people who tested standalone YabaSanshiro on this board and were disappointed, and libretro-kronos is most likely slower than YabaSanshiro on this kind of board. However i intend to buy one of those to do some tests.

Yeah, i know those videos, and i know people who tried the real thing too.

I recently installed retropie on my Raspberry 4 and one of my main goals was to emulate the Channel F System. (my first gaming console when i was a child). I did a manual install (i missed the experimental package) and it works fine with all roms.

Unfortuneately i cannot run the multirom from Sean Riddle.
http://seanriddle.com/chanfinfo.html
I see the game selection screen, can change the games but i cannot start a single game.

Is it a problem of the Rom, controller config or the Emulator?

PS.:
Meanwhile all works fine. It was just a controller problem. I love to remember this old console despite the games are really bad. But if you ever had the original, you remember the childhood and the hours i have played "Maze" wth my friend.

For new games, this is probably not even worth a try.

Even the current version of MAME requires a good number of samples but Donkey Kong was fully emulated (no samples required) with version 0.116 and mame2014 is based off of version 0.159 so that's kind of interesting.

@chemdream said in Libretro-Mame-Latest (experimental):

I swear I googled this and couldn't find it.

If I installed the experimental package of mame-latest, does that install mame 0.200(or whatever the latest is at the time of reading this) core? Or will it install a different version. I wasn't sure how fast mame releases were turned into cores.

I have the latest updates of RPie/Emulation station on AMD Ryzen, Ubuntu 18.04.1.

Thanks!

The repository for libretro/mame merges the new MAME code in usually within a week or 2 of a new MAME release.

So the current lr-mame code includes all the mame0.200, changes in mame 0.201 will be added in in about a week or so (ish)
