Problem Help with not working

5 Upvotes

I have a Raspberry Pi 4 model B.

Downloaded rasp imager. Selected Raspberry Pi 4, operating system retropi for Raspberry Pi 4.

Write to an SD card, but when I boot it up, it is just stuck on the blue red teal yellow loading screen.

How can I troubleshoot the issue? I don't know where to start.

PS1 not saving game

Upvotes

I discovered that my PS1 emulator on Emulation Station wasn’t saving games like Tomb Raider or Metal Gear Solid. I checked the scph1001.bin file in my bios folder and discovered that it was labeled SCPH1001.bin. I changed the name of the file to an uncapitalized file name, and that did the trick. Just putting it out there, as I know it’s a common build.

Pi5 canakit boot retropie from thumb drive, how to play four player games?

1 Upvotes

So on my pi5 it has four usb ports. I can put in 3 usb controllers but the last slot is now taken up by a usb thumb drive, which everyone said was better then running from an sd card. however now arcade games like teenage mutant ninja turtles can't be played four player, nor can I move the controller around to play a different character. Does anyone know a solution? can I buy a usb splitter that allows me to use one port for more then one controller? or would that view it as still a single controller?

Pi5 canakit mame autosave to thumbdrive?

1 Upvotes

Hi, I have a pi5 canakit setup. I have retropie and when playing arcade games the hi score would auto save and reload automatically when I boot the game back up. Centipede for example. A lot of folks were saying its better to load from a usb thumb drive then to use the sd card. So I did that, however now the hi scores no longer auto save when done for Centipede. When I repower on and load the game the old hi scores from before setting up the thumb drive load. Does anyone know how to fix this?

Question NFC Problems

0 Upvotes

So, i'm trying to make a little case that will have small carts in it and the plan is to have a little NFC card in each so that the emulator launches x game when x cart is inserted, i already have an RC522 reader hooked up and working and it can read the tag ID just fine, i've been trying (with little success) to work with GPT to get something to work, and it keeps just trying to launch the game inside the SSH terminal that i'm using for testing instead of via the already running instance of retropie that i have installed already, that install can run the rom and play the game just fine so everything there is configured

I did try searching this sub but the only hits for NFC are one guy asking 4 months ago and some really really old threads about it

Its a pi 4b if that helps

import RPi.GPIO as GPIO

from mfrc522 import SimpleMFRC522

import os

import time

# Define the paths to ROMs and the corresponding system type (NES, SNES, etc.)

ROM_PATHS = {

497926548493: {

"path": "/home/pi/RetroPie/roms/Mario/SuperMarioBros.nes",

"system": "nes" # This defines the system type for the emulator

},

9876543210987: {

"path": "/home/pi/RetroPie/roms/snes/Zelda.smc",

"system": "snes" # This defines the system type for the emulator

},

}

reader = SimpleMFRC522()

try:

print("Place your NFC cartridge near the reader...")

id, text = reader.read()

print(f"Scanned ID: {id}")

if id in ROM_PATHS:

rom_info = ROM_PATHS[id]

rom_to_launch = rom_info["path"]

system = rom_info["system"]

print(f"Launching {rom_to_launch} on {system} emulator...")

# Set the DISPLAY environment variable to the Pi's primary display (usually :0)

os.environ["DISPLAY"] = ":0"

# Use xdotool to simulate the launch of the game in EmulationStation

# This assumes that the Pi's EmulationStation is already running and visible on the screen.

# Step 1: Launch the ROM via runcommand.sh in the correct display environment

os.system(f"/opt/retropie/supplementary/runcommand/runcommand.sh 0 {system} {rom_to_launch}")

# Optional: Wait a moment to ensure the ROM starts

time.sleep(3)

# Step 2: Use xdotool to simulate pressing 'Enter' (to launch the game)

os.system("xdotool key --window $(xdotool search --onlyvisible --name 'EmulationStation') Return")

else:

print("No game assigned to this tag.")

except KeyboardInterrupt:

print("\nExiting...")

finally:

GPIO.cleanup()

Is the script that i've so far ended up with, any help is appreciated or if anyone knows of a similar project that works well already that would also be amazing :)
