Hacking Ubuntu VM with Pegaswitch Libtransistor and RetroArch PreConfigured

[yardie]

New scripts updated to include NES, GBA emulators
Easily select the option you want to start building. Remember to put your roms in the RetroArch/fs folder before running the buildretro script

The first script:

• removes and rebuilds libtransistor, snes9x, vba-next and fceumm from their github sources
• creates fs directory

The second script:

• make-cleans the retroarch folder
• prompts you to select which emulator you want to build for
• copies the respective libretro_switch.a to the RetroArch folder and builds the emulator .nro file

I am thinking about updating the script to give you a choice between snes , nes and gba retroarch

Do you have the source link for the ace loader?

umm... it's already part of libtransistor? If you need to update it:

cd /path/to/libtransistor/projects/ace_loader
git pull origin master
make clean && make LLVM_POSTFIX=-5.0

If you want half of a clue how this stuff is set up, I suggest you read here: https://reswitchedweekly.github.io/Building-RetroArch/ and here: https://reswitchedweekly.github.io/Development-Setup/

And if you want to also set up the image for 3ds stuff, I HIGHLY recommend you start by using the perl script, then update ctrulib (when installing, use sudo -H make install, that goes for installing python stuff as well (sudo -H pip install pycryptodome, "sudo -H pip install git+https://github.com/TuxSH/firmtool.git", etc)). Perl script is here: https://github.com/devkitPro/installer

yardie you a lifesaver tried running script and got error about recipe for target fs.squashfs failed?

thanks urherenow i will try build ace.nro this way i had tried just typing make

Not sure if anyone still uses this, but when I downloaded the VM and run the scripts they were no longer working. So I have updated them to fetch the missing dependencies (only for this machine it will not work on a vanilla machine, although if requested maybe I can do that) and instead of always download the repositories, just do that once and next time, update with latest changes. Also, now ace.nro being compiled on scripts.
So the steps are:

1. Unzip the files wherever you want and give them running permissions
2. Open a terminal and run ./buildenv.sh
3. Add the roms to ~/RetroArch/fs/ as said before with lowercase characters with no space
4. In the terminal run ./buildretro.sh and choose the library accordingly to the roms added before
5. At this point, if there was no error, the ~/pegaswitch/nros dir have both the ace.nro and retroarch.nro files resultant of the compilation
6. Now on the terminal write pegaswith and the pegaswitch window will be visible.
7. Insert the DNS IP shown in that window to Switch network DNS configuration.
8. Now try to connect the Switch to pegaswith by attempting to connect to internet. Retry this step until connected to pegaswitch with success (could take more than one try)
9. Open another terminal and enter nc -v -l -p 2991
10. Now back to pegaswitch window, in there enter runnro ./nros/ace.nro
11. On the previous terminal window now there should be some action. If there is not something like this on the terminal:
    - starting push server ...
    - IP is 192.168.1.110
    but this:
    searching for webkit ...
    - ready to exit
    Press X on the Switch once and that should do the trick.
12. Now for the final step open another terminal and go to ~/pegaswitch/nros dir and do ncat --send-only switchip 2991 < retroarch.nro note that 'switchip' must be the IP shown in the other terminal, in my case ncat --send-only 192.168.1.110 2991 < retroarch.nro
13. Look at the Switch, it should be running the RetroArch now.

P.S. If wanted to try another core emulator or another roms, just run the second script (start in step 4 and continue).

Thanks yardie for the initiation on this.

Create the folder manually. Maybe the script doesn't create it

I'll update my script to include the updated stuff
I dunno what his script does

this error was with your v2 script

Script needs updating
Gonna work on it later tonight

trying to build snes9x again

Strange, in line 27 the code is similar to the one yardie had.

read emu
if [ "$emu" == "1" ] #line 27

It should replace the "$emu" by "1" but instead replaced it by ": 1:"
I will try to search for more info on this.

Edit: Ok after reading more on this, I think I found the cause on StackOverflow.
You are executing the scripts with sh which has a less extensive syntax, so, open terminal and run with ./buildenv.sh and ./buildretro.sh instead.

Good instructions i have question. Is vgmoose retroarch cabable moving joycons attached to portable mode without removing them to unit.

Good instructions i have question. Is vgmoose retroarch cabable moving joycons attached to portable mode without removing them to unit.

Yes, with vgmoose's build you can use the joycons while attached.

Btw, anybody knows how I can use other cores? I found several compiled cores (f.e. GearBoy) here:

https://drive.google.com/drive/folders/1L5r_OhnMeFK0fE9gQiGIWTEPJTn11l9y

But whenever I rename them to libretro_switch.a and replace the original one with it, I get an error (something along the line, that retroarch_switch.a could not be created). If I rename it to snes9x2010_libretro_switch.a and replace the original one with it, I can create a retroarch_switch.a and can run it, but it still uses the snes core and the Super Mario World Rom (even though I placed a Gameboy-Rom in the FS-Folder). I could need some help.

i dunno if this help but found this tuto. https://gbatemp.net/threads/how-to-build-vbanext-only-for-people-with-ra-and-pega.493795/

mv the libretro_switch.a to the RetroArch folder and insert the Rom of your Choice into the Fs Folder

and build with that command make LLVM_POSTFIX=-5.0 -f Makefile.switch (only for non arch systems)

dont forget to delete bevor each build the fs.squashfs (not the one which ends with .o or .c) this line im thinkin its maybe some kind of cache to earlier build and need to del. But always try if it works

Just read the error, you need to install elftools.

emphasis on the "i really suck at linux" part

Hello i tried to compile vgmoose retroach and get cannot compile fs.squasfile cannot found
. I heard this must be delete on original retroarch .

i hope launcer release is this week.

Edit fixed it its my typo on fs folder naming named it to ls instead of fs. Now its compiled to nro.

 

[MlSTERT]

If I want to create a nro file to be emulated by yuzu/ryujix it will work?

(something like a gb/genesis rom)

Thanks for the tip, and now i get this...
