@hooperre Hello, little late but another solution, but unfurtonatally not so pretty ,it is to take a look at BS Zelda fourth quest

Has anyone tried to implement it in retropie?

UPDATE: I managed to get it to work on raspberry pi 4, but anything runs very slow and is definitely unplayable unfortunately.

@mitu said in Raspberry Pi 5 Speculation:

I don't think a Pi5 is in the works.

Given the timelines involved with designing and validating new hardware, especially when it involves chip design, we can be very certain that Pi 5 development is quite far along already. I know a Pi employee (jamesh, on the forums) mentioned already ~1 year before the Pi 4 was released that they had a good understanding of what the Pi 5 would be. I'd guess that at this point we're at most ~1.5 years from a Pi 5 release. I would hope to see it already this coming summer, but that may be a bit too optimistic.

Of course, the Pi 4 has still not peaked, since we're still waiting for Pi OS 64-bit, the full KMS video driver and Vulkan support. Personally, though, I believe the Pi 5 will in large part compatible with all the SW development work that's going on now, i.e. they will most likely keep the GPU very similar (at least from an architectural perspective).

It's pretty hard to speculate about what the Pi 5 will look like, but I mostly agree with @george-spiggott. Regarding using A75 cores, power consumption of the Pi 4 is already pretty much at the limit for what's practical when it comes to passive cooling. It's unlikely that they'd increase it further. This makes it challenging to provide a generational performance leap without going down to more dense manufacturing processes (such as 20nm or 16nm). So, I'd expect a process upgrade for the Pi 5. I also believe that at 16nm (and maybe also 20nm?) they will need to make some provisions to be able to keep the 3.3V I/O on the 40-pin header, since the silicon is not 3.3V tolerant. This will add cost and complexity.

My hope for the next Pi is that they're able to alleviate some bottlenecks in the design. It seems like memory bandwidth is lower than it should be, possibly because of internal bus limitations. My guess is that this is one of the reasons the performance of N64 emulation is still quite bad, despite seemingly not being particularly CPU or GPU limited on the Pi 4.

Thanks for the useful update @rkoster, I wasn't aware of those changes.
The .lha files run under Retroarch for windows as well without problems!

@ecks said in Raspberry Pi 400:

things like debugging when needed?

You'll find A LOT of uses for a keyboard once you get into it. I use a Bluetooth keyboard all the time.

@red732 a shader could do this. eg: https://github.com/libretro/glsl-shaders/blob/master/misc/flip-horizontal.glsl

any arcade game that was available in such a cabinet probably has a system option to run it in a flipped mode - maybe in the service menu or dip switches. eg https://retropie.org.uk/docs/lr-mame2003/#service-menu

@ericmartin i would check out redbubble.com or other sites like it. (I don't work for or own equity for redbubble or other sites that sell stickers.) You can search sticker designs by keyword and purchase ones you like. Good luck!

@thelostsoul thanks, I searched on GitHub but didn’t find the Retropie branch.

@ericmartin this pretty much only applies to mame and FBNeo. Arcade games mostly. Those 2 have a sort of database that knows what version of rom that it needs to run. Older roms may have been dumped with mild bugs, that may or may not run 100%. Over time, games have been dumped using better Methods and the arcade emulators update their code to only run the better dump and abandon the old.
if you are trying to use other emulators, like Nintendo, sega, etc. they don’t have any checks. You don’t have to worry about romsets there. They will just try to run whatever it is given. Good dump, bad dump, doesn’t matter. Bugs and all.

@rubencg said in Have there been any news about Vulkan Drivers for the Pi4 since February?:

Pi4's Vulkan driver has been merged into the Mesa repo. https://www.raspberrypi.org/blog/vulkan-update-merged-to-mesa/

hmmm... wouldn't get your hopes up too high.

I compiled and installed using these instructions

then i tried some things

a self compiled version of ppsspp with vulkan support. conclusion: vulkan works, but framerate on vulkan lower than with opengl backend a self compiled version ofr retroarch with lr-mupen64plus-next with vulcan support. On the normal open gl renderer it works, but gives a segmentation fault on the angrylion vulkan rendererer a self compiled version of retroarch with lr-parallel: same segmentation fault on the same renderer

so apparently a lot of work to be done before we get benefits using vulkan....

Has anyone had any issues with audio?

My audio seems to work on launch of steamlink. Then stops suddenly during a game.

It seems to mute the volume during the game. Easy enough to put back on the laptop... But can't seem to do it in game? Can anyone help?

Well good news. Got a cheap Ostent adapter on Amazon, rebooted the Pi, and it detected it straight off. Working great in MAME!

(Quite like your idea of opening it up and putting a Pi inside it to have a portable arcade machine :) )

@CrazySpence did you update RetroPie-Setup first? That dependency was added recently.

My favorite for all games is crt-pi, I love the look that the scanlines give. It looks good with everything from psx, to gba, to snes, to arcade.

@Zering
yep
asked help there
thanks :)

Yes, it requires some setup but it's working on my Retropie on a Raspberry Pi 3B. Loads of fun and laughs with the mates, strongly recommended.
