The new Raspberry Pi 4 is here!!

[mitu]

@Brunnis That means using X.org or just the KMSDRM driver ? RetroPie - at the moment - uses the old VC4 driver (OpenGL ES), without X.org.

[KN4THX]

I am not sure if this has been mentioned but does the addition of USB 3.0 mean significant increases in sdcard read/write speeds?

[thelostsoul]

@KN4THX Yes, the USB-3 speed is mentioned and tested here: https://www.tomshardware.com/reviews/raspberry-pi-4-b,6193.html
Here is a quote:

With a Mushkin 120GB external SSD attached to one of the USB 3 ports, the Pi 4 B managed impressive read and write transfer rates of 363 and 323 MBps respectively. That’s nearly ten times faster than the 3 B+’s marks of 33 and 34 MBps.

Edit: I just realized you was asking about sdcard speed. A good sdcard reader should be still faster than before, depending on the card and the reader off course.

I have so many things I want to test with this because of that new CPU, my goodness.
Some of the things not already mentioned elsewhere on this thread that I want to test include:

• Gnash (I'm not expecting full speed obviously, but it should at least be somewhat more usable)
• PC-98 (Probably gonna get some decent speeds with a decently high clock multiplier)
• DOSbox running Windows 3.1 (Mileages may vary on this one, the Pi 3 is technically good enough for this, but speed improvements are still nice to see!)

Can't wait to get mine to play around with (once RetroPie gets updated for the Pi 4, at least).

[Headcrab]

I've read in a technical pdf that : the Ethernet packets do not need to be repacked into USB packets anymore, thus latency and processing overhead are decreased on the Pi 4

Let's see if this makes even a tiny difference in applications like moonlight or SteamLink.

@dankcushions I think the 3DO could be doable as well as some (but not all) of the Atari Jaguar's library too.

Personally, It'll be interesting to see how Sega Saturn emulation will improve but given that Mednafen's Saturn core is quite demanding I can't see the same level of compatibility happening on a Pi4 myself. Though that said, some of it's 2D games will run very nicely.

Also will the improved and updated Reicast be appearing at some point with it's Sammy Atomiswave support?

[chubsta]

All I am interested in is being able to play Gauntlet Legends in MAME - anyone reckon this will be possible without frame rate issues etc?

[Cornervizion]

@SuperFromND Hopefully DosBox running with V-Sync would be dandy.

[quicksilver]

@Cornervizion Currently you can enable dispmanx for dosbox and this takes care of the screen tearing issue.

[quicksilver]

@chubsta Only speculation at this point, so no one can say for certain. We'll just have to wait until some of the devs get their hands on one.

What I'm thinking is: will RetroPie support dual screen? That would be great for building your own NDS. It will be quite a fat one, I'm afraid. Does some frontend support use of dual screen already? If not, how much effort will it be to add it?

[Jiryn]

I just need a good case for this!
I got an alluminum case for my 3, which probably won't fit this.

Um, which are better FANS or HEAT SINKS? I've been using the later with my 3B.

[Marcel]

@Jiryn Using both works best. See

[Jiryn]

@Marcel Doesn't fit my current case.

[Cornervizion]

@quicksilver I did attempt it back on my Pi2 but this came at the cost of performance. I might try it again shortly on the Pi3.

Here's my current case, yea I couldn't do a fan and heat sinks in it.. but I love the form factor and design.

Those ones you linked look great!

[dd0ck]

with the Gigabit ethernet, is having big ROMs (PSX, Dreamcast, etc.) stored on a NAS an option? These little SD cards can only hold so much...

[ScottyPsArcade]

Killer Instinct 1 and 2?! I'll buy just for that... haha
