Re: DVFS Firmware

Just so everyone knows, CPU overclock works fine. The only issue is with GPU overclock with the latest rpi-update. Leave out the GPU overclock until sorted and it will be fine. You can of course always revert back as well. Not very hard.

Re: Can Pi 4B 4gb emulate Xbox 360?

The best Pi 4 can do is N64, Gamecube (some games close to full speed), a few Wii games but not at full speed, the original Playstation and Dreamcast. Those are the highest spec systems known to work.

Re: DVFS Firmware

I get the same symptoms as well with the update. You can run an overclock on the ARM but not on GPU or it fails to boot.

Re: Attempting to Build Mame 0.214 on RPI 4

Building mame on your own will result in better performance than the version in the repositories. You can also use the newer ROMs correctly as well. The only problem I have noticed when building on your own is that certain games will cause name to crash. California Speed is one such game that will c...

After build is done, revert your swap back to default. Issue the commands to stop and start service and enjoy mame.

The build has been going on for several hours and I now have many executable programs showing up. It looks like it is actually going to succeed this time. I am also building out the mame tools as well which probably explains why it is taking so long.

Re: Attempting to Build Mame 0.214 on RPI 4

The build has begun. Without using -J4, RAM usage is so far staying under 1 GB. I do remember when using make -J4, RAM usage was close to 3 GB. Build speed is slower, but I will take that as long as it succeeds.

I have a 4 GB board. I will attempt without -J4 and see where that leads. I have not tried that yet. I have not enabled swap, but if I were too, I would prefer it to use one of the connected USB 3 hard drives rather than the SD card. The USB 3 hard drives more than double the speed of the SD card an...

Re: Pi 4 - full specification of VideoCore 6

Yes, it is quite an old one. It's hard to quantify the performance of the BCM2711 against PC's and dedicated graphics cards. It was designed to be low power (as in power efficient) and was not designed to be comparable to a modern gaming rig several times it's price. The best comparison I can give i...

It is definitely better than a Radeon 9800. That is what I have been able to determine so far. It can play Doom 3 at 720p resolution fairly competently and is likely to see a little improvement as the drivers continue to be worked on. If you want to visualize a comparison, think of it as equivalent ...

Re: PI 4 4gb 4k playback on chromium youtube

You can also get the Youtube add on for Libreelec and view 4k Youtube videos that way. I am sure H265 will be working in Raspbian in the near future. The GPU drivers are still being fleshed out at the moment and are still a work in progress.

Re: Sense Hat on RPi 4 ...

You could always place the Sense Hat in a separate connected to the Pi 4 via a ribbon cable. That will help keep the sense hat away from the board and it's heat while at the same time allowing you to pursue a cooling solution such as a fan shim.

Re: Official Rpi4 case needs a fan

The fan shim is a solution, but if you are handy and use a small hole saw and drill bits you can easily modify it for a fan. Your fan can then be powered from the GPIO pins with ease.
