@androidonpi The errors appears because you're running RetroPie from the desktop environment. As @dankcushions mentioned, this is not a supported configuration. On the Pi4, drastic will run by starting an X server first (as a few other ports already do), if you're already running in a desktop environment, that won't work.

@bio_hazard1282 The PS5 controller has a touchpad right? If so you should be able to use that to emulate the stylus.

@retropieuser555 your welcome 👾😉

I counldn't figure out how to use drastic, so I used Ir-dusume 2015 instead, which works great and is 10x easier to use.

@mitu @sirhenrythe5th Whoa! I'm very sorry. Please don't hold anything against me.

UPDATE-
I have Pokemon Black ordered off of Ebay and on the way here. Thanks for the suggestions.

@mitu yup it seemed to remember the controller when it was the only one plugged in. What I’ve noticed is that the controller is switching to and from JS0 to JS1. I just configured it with the keyboard and it’s JS0 again. I’m wondering if having multiple controllers plugged in at one time might be the issue. I’ll try running Drastic and using just the lone PS4 controller and hopefully it works out!

Thanks again!

I've been running PCSX2 for a while, it is heavily optimized for Windows and you are going to have a significant performance drop unless your machine is a beast.

@mat The instructions look like Windows, but only because a windows program is used to prepare the cheats file. Drastic doesn't run on Windows.

@driagonv

I'm afraid not at the moment and unfortunately I don't think that is bound to change anytime soon. The DraStic team has had a bit of hard luck, losing key members and even a certain amount of their source code. Right now, the main developer has the all-to-common problem of not having enough time to work on the project. However, there is talk of the existing source being opened up, at which point you'd likely see a lot of revitalized interest and advancement. Perhaps even a libretro core.

@breyyne If you have afolder for DS then it is probably installed. A
Are the rom extensions .nds or .zip?

@reeebs said in [Rpi3] NDS touchscreen:

I don’t expect nothing in particular, as the two positions - the real one of my finger and the one of the pointer - are completely wrong: if I move, it moves too, but when I am in a corner it starts from the center and so on

That's very telling behavior and explains why the Dolphinbar wasn't recognized. The touchscreen is apparently being read in this case as a standard relative coordinates mouse. If it were being read as an absolute coordinates pointer device, the cursor would snap to wherever it was you touched at. Needless to say, this limitation combined with the wide area required to receive input really hinders precision.

I took the advice from @jonnykesh and it totally worked, the problem was indeed the custom es_systems.cfg that was created when I ran a script for installing it, thanks for the support

Alright, thank you both for your responses. I'm going to keep looking and I will try to make it work. I'll post back if I found anything.

@sselph worked great on all of the Systems but the sega Genesis Mega Drive. Thanks again for all your help.
