@fatfrog fba2012 is unmaintained and you shouldn't use it.

If i had to make a blind guess, considering you didn't read https://retropie.org.uk/forum/topic/3/read-this-first and provided absolutely no information about your setup, i'd say it's some kind of screen refresh rate issue.

@Striderx99 said in Wolfenstein 3D and Spear of Destiny no longer working with WOLF4SDL:

Build Operating System: Linux 5.10.17-v8+ aarch64 Raspbian
Current Operating System: Linux retropie 5.10.52-v7l+ #1441 SMP Tue Aug 3 18:11:56 BST 2021 armv7l.

That is the kernel version, not the OS version - which one of the 2 doesn't work ? How did you install the one that's not working ? Why don't you add the full info asked in https://retropie.org.uk/forum/topic/3/read-this-first.

I'm stumped about which files I should look at next to see if I can pinpoint the reason for this issue

Please post a listing of the /home/pi/RetroPie/ports/wolf3d folder.

@mitu Yes, so trying a few more, I did get an FM Towns Marty specific scrape for "Muscle Bomber: The Body Explosion" from thegamesgb. There seems to be a lot more content for this system in Screenscraper, though.

@jorgito13 the problem with the old compatibility table is RetroPie has changed its underlying OS over the years and all the emulators have been updated since it's creation, so it would be safe to say that some of those entries may not be all that accurate anymore. The new table while not as enriched, is auto-generated based on the lastest XML DAT file used by the core. The entries on that list mirror the warning flags assigned internally by the drivers, so it should be some what accurate with the state of those games.

If there is a particular piece of information you want to be added to the new list, or sorting method. I maybe able to update DAT Magic (what builds those lists) to auto-generate some of those features.

There's no one site fits all, that's why you probably can't find a straight answer to 'optimization' questions.
For earlier systems/consoles, there's little need for optimizations, since they are emulated full speed, so optimizations will not get you further. In RetroArch, a per-game optimization in this case is the runahead number of frames, to reduce input latency. Here you can experiment and see how the game feels with different values.

For later systems/consoles, there's some room left for performance improvements, so you can try tweaking the Core options to remove/modify some performance intensive options. Not the overall RetroArch settings, since the defaults for the video/audio drivers are ok, though you can experiment with per-system's shaders and per-game run-ahead settings. Maybe some other users have some more ideas on what per-game/system tweaks can be done.

Choosing Shaders can be also done on a per-system (same shader for all games in the system) or per-game basis (i.e. arcade games are not all similar and you may want to have a vertical CRT shader for some, horizontal for others, non for the rest, etc.)

Furthermore if you are in the game, and you change settings in retroarch -- does it save automatically, or do you have to force save it and load it? I guess im just a bit confused on this topic.

RetroArch's settings are saved differently:

input setings are not saved to the main config file, you can save a remap/override (this is RetroArch specific). shaders are saved separately, from their menu - per game/folder/system/core (this is RetroArch specific). core options are saved immediately. They are also applied immediately, but some of them require a restart of the core/game (this is RetroArch specific). 'normal' settings are not saved automatically and this is a configuration set by RetroPie. I advise against saving the configuration after changing values or enabling 'save on exit' - instead save a system override after changing the values. It's easy to revert your changes if you're using an override by removing a file instead of finding the option you changed in a file with hundreds of lines and reverting it.

@TPR Hey @TPR I am experiencing the same problem with my N64 roms. Did you end up fixing it? Thank you

@Folly No worries, thanks for trying. I tried a few of the other TRS80 models but they don't seem to be any better :(

@Quantoxhead said in DS emulation on Raspberry pi 3?:

Or is that the most efficient one?

I think is the only one that performs well on the Pi3 .

@Arrafart Thank you!

@sugarfree said in Using Vulkan with RetroPie:

@TPR

It's not merged yet, but I'm sure it will be when the time comes. See: https://github.com/RetroPie/RetroPie-Setup/pull/3785.

To answer your previous question: yes, the Vulkan driver provides noticeble better performance with the Flycast, Dolphin, and PPSSPP emulators. The extent of the improvement depends on the game.

OK thanks. Those are the emulators I've been using it on.

@shoe0402 Heyyaa!!
I am also building a handheld for myself right now, so getting to the point. The first component you gotta figure out is which Single board computer to go for, which depends on what games you want to play. After you've figured that out, then, you can head on over to figuring out other components.

A fix for this issue has been added to RetroPie-Setup, making the splashscreen work on any HDMI connected port on the current/old Buster release.

Hello, i recently bought a cabinet that had, what appears to be, a very old i-pac ps/2 controller in it. This particular version does not look like the one on the website here:
https://www.ultimarc.com/control-interfaces/i-pacs/i-pac-2-classic-ps-2-version

The page above doesn't exist - the site shows an error for a missing page.

It does not look like that. The model in my cabinet has two ps/2 ports on opposite ends. They are labeled PC and KBD.

Question is will retropie support this old ipac controller via a ps/2 to usb controller? And if so would I follow the programming instructions here?

I'm not sure, but if the IPAC identifies as a keyboard and it works without additional drivers, then it should be ok - RetroPie (or Linux rather) can use the keyboard.

I’ve got the same question. Any help on this issue?
