@arvis1 NEVERMIND, i found the issue. In this thread: https://retropie.org.uk/forum/topic/34661/solved-remove-pulseaudio-and-revert-back-to-alsa/3
The issue was that using purge on pulseaudio did not fully uninstall, so you have to go into the retropie setup as detailed in this guide.

RetroPie is just a RaspiOS Lite image underneath, so a regular Linux/Debian installation.
You can add your code to the autostart.sh script that RetroPie uses to start EmulationStation (see here how to access the script) or just create your own service to start on boot (see here).

The RetroPie PI image uses the Raspbian Lite distribution as its base, so if your code can run on Raspbian, then it's highly possible it will also run on a RetroPie image.

Here's an article with three different options: https://www.ostechnix.com/test-your-bash-skills-by-playing-command-line-games/

The last one can be played offline. I haven't tried them all, but they should be plenty to teach you the basics.
You should know when to stop though. The wargames site goes into some very advanced stuff which you'll never use. Most of the stuff you need will probably be in the first level.

@TitQuentin said in FFIX some code doesn't work properly:

-pcsx-rear

I'm having a very similar issue with FFVIII but can't seem to get any help on the boards. Did you ever figure yours out?

@rbair6600 Thanks for sharing your solution.

@loubron Google hide boot text then you can use run command to hide the emulator options. There is a kids mode but it's in beta effectively in experimental packages. I would study the wiki a lot of the info is there. You will not get perfect experiance but you can get bloody dame close

@andershp
We can try and help you but you're going to have to give us more to go on, if it works on PC it should work on the raspberry pi exactly the same (providing the version of ES is the same). Paste a copy of the changes you made exactly as they appear in the theme you modified on the raspberry pi, or if possible upload the xml somewhere for us to see - it could just be a simple mistake that we can spot.

As the text tag list doesn't contain something like outline

Available tags:
pos, size, text, color, fontPath, fontSize, alignment, forceUppercase, lineSpacing
Source: https://github.com/Aloshi/EmulationStation/blob/master/THEMES.md#text

you have to use a font with a outline. Just search for a folder called "art" in the root of the theme you want to edit and replace the old font with the new one.
If you don't want to mess around with the XML files, rename the new font like the original one was called.

That's it. If you need more help or a finished solution, tell me.

EDIT: If a change of the font color would fix your problem to you could edit the "main" XML (it isn't called main in most cases), located at root of the theme folder. Edit the color hash in the <color> tag

@BuZz

Yep, simple markup is definitely needed for this, at least several different menu item types: regular (button), input, checkbox and maybe numeric slider. This should be enough to stay within the EmulationStation. Onscreen keyboard is needed anyway, even without this nice feature.

Of course fork is a good way to implement this, but I like RetroPie and I want it be better for everyone. So I shared this idea and wanted to hear you opinion first.

I could narrow the problem down a little bit. When the db9_GPIO_RPI driver is not loaded and i try to unload it, I get:

"modprobe: FATAL: Module db9_gpio_rpi is not in kernel"

that makes sense but I tried to avoid that with try/except. Seems it does not work. Any idea why?

@backstander it's not work both of them
he ask me for IP and password and when I type the default one he said it's wrong :(

@subz No worries man I appreciate you coming back to say you got it sorted. The forum is here for people to search first and foremost. Most people find a solution and then never come back, not caring about those that come behind them.
