@polinator1993 Wow, great, where did you order it?

@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.

Head over to this thread for updates on Mario Kart Double Dash:

https://retropie.org.uk/forum/topic/30541/dolphin-elumator-running-on-rp4b-64bit

Oh ok, thanks @mitu

For the complicated option (I have not tried this btw :) get one of those backwards compatible PS3s and make it dual bootable with Linux, run PS2 games on the straight ps os and maybe other emu's on the Linux boot?

:) I see youtube videos of people doing some of that but don't really know if the whole thing is possible. Might be fun to look into though if you have too much time?

edit: and maybe you could try to find an broken PS2 to just use the enclosure, take apart the PS3 and fit it into the PS2 shell. Voila! A PS2 made out of a ps3! :)

Please use topic titles that give an idea of the contents.

@Unknown Even if it was supported, a pi4 will never run most games at a playable speed. Buy a used wii with gc support from ebay or a shop. It's sometimes cheaper than a pi4.

If you've watched videos, the performance is not worth the hassle. If I really want to play gc/wii, I'll use an emulator on my pc, or use a real wii which I got for ~$30 many years ago.

I installed dolphin on Ubuntu 20.04 it ran Mario Kart Wii Ok I use 4GB of ram

@p33te you may be right, but he wrote in his topic "has anyone made a theme related on GameCube?" so i guess he allready has a case and wants a theme for that.

I got this resolved on my system (Ubuntu 18.04, Intel i5-3470 iGPU) by installing and using Vulkan rendering. I did not have to download the Sys folder from the Dolphin source repo.

I must note that Vulkan is not supported on any CPU earlier than Ivy Bridge, so this may not be a viable solution for some people. Mine is the earliest possible generation chip this even works on, so I guess I got lucky.

Install Vulkan support and testing application

sudo apt install -y mesa-vulkan-drivers vulkan-utils

Test Vulkan (successful example):

vulkan-smoketest

Modify the GC and Wii cores' config files to use Vulkan renderer:

sed -i '$ i\video_driver = "vulkan"' /opt/retropie/configs/wii/retroarch.cfg sed -i '$ i\video_driver = "vulkan"' /opt/retropie/configs/gc/retroarch.cfg

After doing this, GC games worked fine. I'll come back and modify this post if necessary whenever I get around to adding Wii to my system.

@mitu sad day

i feel stupid, thanks alot

EDIT: wow performance is absolute garbage, how can this be, i looked in some forums, and everybody is like "oh you need dual core" dude i have a quad core 3.4 Ghz i7? Is it the settings or is it ubuntu itself?

Ok thanks

@SingingCoyote13 said in Is it possible to read Dreamcast/Ps2/Gamecube discs into an emulator directly via the DVD drive on Retropie/PC or need they all be dumped to a .cue/.bin/.chd/.cdi etc, and how do i dump these discs anyway ?:

i was wondering if dreamcast ps2 and gamecube discs need to be dumped to a file for use with retropie pc version, or if they can be read via the dvd/br drives in pcs directly in some of the emulators ?

As far as I know, pcsx2 can read the DVD drive directly, for reicast/dolphin, you'll need a disc image

if they need to be dumped,. i believe dreamcast discs have a different layout than normal cds, can those be dumped with a regular dvd drive ? Or is it so that if someone wants to play these in an emulator he/she has to download official dumps of these discs ? with what program and drive do i need to dump any of dreamcast/ps2/gamecube discs anyway ?

Look around for instructions on how to backup your discs, there are no 'official dumps' provided by the vendor/publisher (though they're plenty 'unofficial' ones). Here are some pointers:

@mitu oh sorry. ok then thanks

I've been meaning to provide an update for the for a while so here goes.

I still haven't fully resolved the issues with the controllers but I've not really had a good stab at it yet.

A few more photos; generally I'm happy. When reassembled the fan blows straight across the compute module (which was the idea) so adding a heat sink so keep it nice and cool.

The HDMI port in not fully aligned - not a major problem but the perfectionist in me doesn't like it - that on the list of changes if there's ever a next version. Also, I'm not too keen on the empty hole to the right, might be an idea to add another USB port in future.
IMG_6607.jpg

Front USB port fits nicely into a slightly modified memory card port but doesn't sit at the correct height - something else to be tweaked.

As for the next version, this is on hold for now. One of the original aims for using the Compute Module was future upgradability base on the assumption future Compute Modules would keep the same interface/footprint. The ultimate hope was the come CM4 or CM5 the power might be there for GameCube emulation.

However, I've read that future versions might deviate from the SO-DIMM 200 interface, hence I'll hold off on making any more hardware changes with this until there's more clarity on what the future holds. It's been a fun process and has taught me a lot on the way - which was the real aim anyway!

@watford98 said in Switching between arcade and gamecube controls:

Q1 - Can i plug some of the mayflash type adapters into one of the ports and have this work in tandem for certain games.

Yes, sure.

Q2 - How would i set it up so that the control type could be switched for different games.

You can use the joystick selection tool created by @meleu [1] or look in the RetroArch configuration editor and switch the player mapping (i.e. P1 would be the GC controller for a certain system).

[1] - https://github.com/meleu/RetroPie-joystick-selection

Pretty much any controller is supported, I have a wireless PS3 style controller and a wired PS3 real controller and both are detected and work perfectly with everything I use

Some games may be a bit awkward to play without specific controllers, but if you can get an N64 controller there are people that use specific controllers for specific systems and one just for everything else

Not all N64 games work, but the vast majoirt do. I have N64 games, but only those they are verified and tested working 100%

This is an outdated list now, but wil give you a good idea to what is possible on the PI3 N64. Quite a lot does work though, mainly concentrating on the popular games for 100% compatibility and support

https://wiki.gbatemp.net/wiki/Wii64_Compatibility_List

Wii/GameCube is really a "proof of concept". It will work, but so incredible sluggish and terrible it really isn't work trying (and probably never will) on the PI hardware. 3DO and SEGA Saturn emulation is also possible and supported. They WILL work but just not quick enough to actually be usable

Not a chance
