Most likely the display drivers disabled the Pi4's GPU drivers by modifying the bootloader configuration.
Can you post your /boot/config.txt file ? How did you install the display drivers ?

I'm running a near identical build but with 2 wired contollers. The only psp games I run are the Williams and Gotlieb pinball games, but they run well on ppsspp. I just had to activate frameskip, otherwise there's minor stuttering.

It may just be that those games are some of the ones that the pi struggles with.

Just wanted to confirm that building RetroPie on current Debian ‘testing’ using RetroArch’s 1.10.3 source works perfectly.

Thanks!

@mitu
i have 2 usb to the Pi
1st wireless keyboard+mouse
2nd bluetooth dongle

reason you're not using the built-in Bluetooth of the Pi 3B+
already try with built in bluetooth
I got the same problem sir

Hi,

screen tearing is almost gone with some extra buffer in config.txt

extra_transponse_buffer=2

What i found is that this extra buffer will help while dispaly rotating.

You'll need some additional setup or driver for the circuit inputs - is the Pi board connected via GPIO to the circuitboard ? What model is the handheld - maybe the vendor has instructions on how to configure the inputs on a bare RaspiOS installation.

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

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

@zemendonca1 in general (as this knowledge can be used for more than just retropie), savestates usually do not transfer between different emulators, or even different versions of the same emulator, for that matter. but in game saves or memory card files typically do. just have to rename them to the proper format of what the other emulator requires.

@shark

Wow, on a hunch I changed the following line in /boot/config.txt and it has corrected the issue.

overscan_scale=0

From what I read this is supposed to be the default setting, but it was set to 1 in my config file. Sometimes all it takes to figure out an issue is to write out a lengthy forum post LOL!

@Abadden1 said in Really need beginners help:

I literally do not know what I'm doing.

@KimDb
hope its not late,I just sign up recently and saw this topic, I have solved this by change this line to
input_map[ui_cancel] keyboard[0,esc] or joystick_button[045e_028e,y] joystick_button[045e_028e,mode]
, for now it can be exit by select + x, I can not figure out why the start button seems can not be detected in this advance mame.

@mitu Makes perfect sense. flipped that value to true in the config and the controller works every time from wakeup.

Thanks so much!

Well... I just figured out what was causing this, although I still don't understand why it was causing it, so if anyone has any suggestions I'd still like to hear them.

I start EmulationStation with the "screensize" command line parameter, because I'm running at 240p on a CRT with a super-resolution (1920x240), and if I don't do that Emulationstation gets confused and scales things wrong. I then use XWindow's built-in scaling to scale EmulationStation to the full width of the screen.

This morning I changed it from this:

--screensize 300 225

to this:

--screensize 300 222

because a few lines were getting cut off on the bottom. I neglected to change the horizontal though, I should have changed it to 296, to keep the aspect ratio at 4:3. Apparently it was the aspect ratio change, even though it was tiny, that screwed the buttons up.

I had moved on to editing my theme and completely forgotten about making that change by the time I noticed the messed up buttons. Oops. :-)

@kiro Thank you, sounds really useful!

@mitu error 404 confirmed... jesus :)

Can you run, from a terminal, the following commands:

aplay -l aplay -L

and post the output ? The error in EmulationStation logs indicated the audio settings for the volume control are not correct. Do you have sound during gameplay, when running the emulators ?

I was able to find a another version of Genetic Species that was split up into .lha files. I won't say where, but you can find it in a certain place if you look hard enough. I unzipped the files within WinUAE (PC) and it created a Genetics folder with all of the files (the one that is the launcher is labeled in red as "Genetics." ). I made sure to choose the 3.1 revision 40.68 kickstart rom. It asked me to select the resolution, but after selecting low resolution under NTSC and the lowest possible dimensions, the emulated machine seemed to run out of memory. I know I'm almost there in getting this to work, but I'm wondering what I should do to these folders (maybe zip them up into a Genetic Species folder?) so that it can be read by one of the emulators successfully. If anyone has any more ideas, thanks for the help.

As far as Assasin - Special Edition goes, I used the same kickstart rom, but decided to delete the three .adf files it used in exchange for one .hdf file. It loads slowly, but it does seem to work. The original set seemed to be the wrong combination of roms, because the emulator kept trying to reload them until it brought me back to the game selection menu.

hi, just following up on a very old topic!

Latest retropie build from the retropie site -downloaded sept 22. I have an ipac 2 and a physical joystick, that works Left Right Up Down and fire in all other retroarch emulators.

I initially had the same issue - I've set the keyboard to port 3 as above, and kempston as port 1 and both lr-fuse, and fuse, 'sees' the L R U D and fire inputs as kempston.

However - when I press a direction the game i'm playing pauses. Same if i use the usb keyboard attached. I've tried changing the options/time to release the key in MS and it seems related. its almost as if a direction key, holds down the key and freezes the emulator or game, until I move in another direction and so on.

I just tried port 1 to retropad and used the arrow keys on the usb keyboard - same effect.

Any advice please welcome how i can address this!

thanks

Last I looked it was still part of the setup script. Can’t remember if it’s an experimental/optional package though. But it does work. Just scraped with it the other day.
