1st I want to recomment you, if you haven't already, to take a look into theinks IPac2 Guide

@joshrdunstan said in IPAC-2 causes Dual Button Press:

My IPAC-2 is an early version, pre 2015. I note that there is a firmware that allows an IPAC-2 to come up on the pi as 2 peripherals - however I can't figure out how - or if - I can update the firmware. When I hit the update firmware button on WINIPAC (V1) it just says "Download started" but doesn't appear to do anything.

citing Ultimarc

Latest firmware files (ver 1.55) for all 2015-onwards I-PAC, Mini-PAC and J-PAC boards plus all Ultimate I/O boards regardless of date. NOTE: Attempting to upgrade a pre-2015 board which this firmware will render it inoperable.

Link for Pre2015 Boards (from linked side above) [edit: No Firmware, just utils as it seem]

Hi, I seem to have the issue that's somewhat documented, where the IPAC-2 I have configured in ES on initial startup, is now causing some double button presses where there's a conflict on what is configured in ES and what's configured in retroarch.cfg. It makes most of the games on MAME unplayable. Both the configured joypad input plus the raw keyboard press are being sent to the emulator.

That's because Mame is recieving the "Keys" from the IPac-2 "Keyboard" together with the "Gamepad-Buttons" from the virtual RetroArch-"Retropad". Depending on the mame core you are using, there is either the possibility from within the retroarch-ui to configure the input mame will recieve, or for cores where that is not possible, the only way I am aware of is to configure the Input via the mame menu using either a real keyboard/gamepad and assigning only real kbd keys or gamepad keys to the functions (or by editing the corresponding .ini (edit: <default>.cfg) by hand (via editor of choice).

@mitu, also a BIG thanks. I recently installed two systems with Xubuntu 22.04.1 and RetroPie. Same issue as described. First time it took me about an hour to locate this post which solved the problem. The last system I had this posting ready and after the first error message (exactly stating the parameters I needed) I fixed it.

@mitu

You’re a star. Thank you very much.

I want to add that I have narrowed down my issue. The sound stops working due to my spi display. interfering with it. I suppose this topic is no longer relevant to this forum.

@Emrop said in Raspberry Pi4 - Retropie - Retroarch : direct access of the cores repository ?:

[...]
And finally the cores folder is empty.

Oh, yes - that's normal. RetroPie works differently than a standalone RetroArch. Just copy your games into the corresponding systems' folder and then launch them - there's no need to start RetroArch first.

Cores are installed in their separate folders and are automatically loaded when a game is started - you don't have to run RetroArch manually. There's no need to install or update them from RetroArch - you can manage them from RetroPie-Setup.

@mozvillat said in Can't save favorites games:

If i delete it with the on screen menu, after a reboot, it came back ??!!!

The proper way to 'delete' a game from the favorites is to toggle the Favourite flag with Y - just like you flag it as a Favourite. The Favorites folder is not a system per-se, but a collection with all the games that have the favourite flag toggled.

@TrisM no problem, pls let me know if I can help you with anything.

@TheAutisticGamer sounds like poor wifi signal. the pi’s wifi antenna isn’t the greatest. It’s just enough to to work, but Depending how far your Wi-Fi is , how many walls it has to go through, how much other radio signals nearby causing interference, ect ect, can effect signal strength. Try using a 2.4ghz instead of 5ghz as they are more robust, and can travel further though walls, ect. easier.
Also it’s not dhcp failing. Even if your DHCP server failed, your pi would still keep its IP address as well whatever the other device on your network. It’s just any new devices won’t get a new IP address.

@mitu said in n64 games 2 player support ?:

Open the configuration file for Mupen64Plus in /opt/retropie/configs/n64/InputAutoCfg.ini (also accessible via file shares at \\retropie\configs\n64\InputAutoCfg.ini) and remove the keyboard entry, see if it changes the player order.

I removed the keyboard entry and rebooted and that solved the problem. Thanks!

@HoffsterX90

Try something like this:

-bank 1 00110111 -bank 0 11011000

@mitu Thanks ! i can't change core settings (just saved them) but i can save remap files ! and that did the trick !!!

Issue with mame2003-plus has been corrected. For anyone following this, Update from source to receive the update.

@Simrose said in lower video resolution to improve performance?:

I have currently default settings with retropie except I disabled 4k in the config.txt as recommended.

how did you do this, specifically? posting your config.txt would help.

@Simrose said in lower video resolution to improve performance?:

I've read on some posts in this forum and from the web that lowering to 720p resolution might help improve overall emulation performance.

i disagree with the premise. 1080p should be fine for pi4 at default settings. reducing the resolution further can give ugly scaling artefacts, especially on a larger TV.

perhaps it's better to state the specific speed issue you're having, and we can diagnose it.

@themazingness
Hi!
Just for log information, I had this same problem today and I solved using this:

make a copy of /etc/network/interfaces
sudo cp /etc/network/interfaces /etc/network/interfaces.old

append to the file /etc/network/interfaces
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

enable the wpa_supplicant service and restart
sudo systemctl enable wpa_supplicant.service
sudo systemctl restart wpa_supplicant

*restart the system
sudo reboot now

@mczx said in Newbie: is this possible?:

can i run actual arcade controls and interface with retropie?

If you really want to use an existing cabinet, there are are some adapters for Jamma controls to a Pi which can help.

If you just want to have an arcade control panel, you can build one from an USB encoder or an Ultimarc board and connect it to a PC/PI via USB. Or use one of the pre-made arcade stick boards like 8bitdo arcade stick, Madcatz, Hori, etc.

@williamcaput said in Megadrive ROM language select:

RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6.1

The 4.6.0 series had EmulationStation at version 2.9.1, your log shows an much older version (2.6.1) is in use. Are you sure you're using RetroPie 4.6.1 ?

The log shows the ROM files are launched fine. I would check the ROM files as @windg suggested and maybe post a verbose log from launching with lr-picodrive. Use pastebin.com for the output, since they're quite large.

i'm wondering if the option of Installing on top of an existing OS would be possible? there are several Ubuntu instances that are supported in this manner. it's worth noting that i am not a Linux or Pi guru, so i don't quite know what the differences are between these Ubuntu options or what the difference is between the Ubuntu PC vs Ubuntu RasPi versions mean for supported software.

@10vorne said in Move 64GB Image to 256GB Card:

just pull an image with Win32DiskImager and move it to the new card with Etcher?

That should do it. Make sure you go into the setup and "expand filesystem" after, to make use of the new space.
