I've been keeping an eye one FS-UAE, as soon as they get OpenGL ES support it sould run at a pretty decent speed on the Raspberry Pi, certainly good enough for A500 emu.

Note: the Raspberry Pi only comes in two flavours... A 256Meg one and a 512Meg one... Both are overclockable, but the 512Meg memory chips seem more tolerant of the higher clock speeds. I run my 512Meg Pi at 1.1Ghz and my 256 Pi at 900Mhz

How many Watts did your 512MB Raspberry Pi consume originally?
How many Watts did your 512MB Raspberry Pi consume @1.1Ghz?
I only supply my 1.1Ghz with 800mA @ 5V when running on battery... So I guess 4Watts

And the A9 boards I've been looking at already run SoftGL.
Not to mention that they run 600 MHz faster (with an already better processor core(s)  - four of them to be exact), before overclocking.
And it has a more powerful four core GPU, four times the memory, and according to Pascal it should be able to run Aeros.

Starting at about $50 more than the Pi.

Also, I'm curious, how well can a Pi handle XBMC?
The A series ARM chips are very nice, but nothing come close to the Pi in terms of price.

XBMC works a treat on the Pi, the graphics core is actually very very powerful :)

That is cool.
A media center system for under $40.
I've tried using some of the VIA Arm11 based SOC based products, but their weak point was definitely the GPU.

And I can't believe you're using so little power.
The startup surge current is a bit larger and I'm not running the ethernet, which can be a bit hungry especially at 100Mbps ;)

What resolution of movies can you watch with XBMC on a Pi?
1080p

-edit- in Amiga speak: 1920×1080x24bit@60Hz

No way!

I assume that is only with .avi format?

What about .mkv or .mp4 or .h264?
Avi is just a container, but all my videos are either m4v or  .h264 :)

Yes the Pi's graphics chip can decode h264 in hardware in realtime... It can also encode h264 in realtime to, that functionality comes free with the Pi

Dude, ur exploding my mind. :)

Does Ouya have all the same magic that Rpi has, just more?

Can I assume that a Ouya would play movies even better than Rpi?


But just because Pi can do something in hardware does not necessarily mean it can play every single movie at 1920x1080 @60fps.  Some movies are much harder to play than others, especially scenes with a lot of small moving objects everywhere while the camera is rotating.  That is phenomenally hard to play correctly.

My bro has this pc with a 2Ghz core2duo and some kind of gfx card and it has severe problems playing 1920x1080 movies.  It can sometimes play them ok but usually the framerate jumps up and down wildly during the movie even when 2 ppl are just sitting there talking to each other.

I need to ask you a question: Do u (or did u) play a lot of FPS games on your home computer?
The Pi has no problem with HD video at all, the Chip was designed for video playback... The CPU core was originally just for housekeeping functions... But the RaspberryPi team use it for running an OS :)

Does that distro support 4TB NTFS drives on the Raspberry Pi?
Read only?
Or Read/Write?

And if not, then what filesystems do ppl use on Rpi that support >4GB files?
I'm using exfs4 (SD cards), and HFS+ (external drives) on my Pi... But it is running Linux, so pretty much any file system will work.

It sounds like the same philosophy as the A1000!
Yeah, actually it does :)

To expand on what I said earlier, the Raspi was designed to be a graphics chip for mobile devices, with a small ARM core to basic housekeeping work. The device actually boots the graphics chip first (as with most modern graphics chips it is a fully programmable processor in it's own right, and has it's own OS and kernel that is on the boot SD card), and then it brings the the ARM core online and sets up the operating system ready to boot. Once the ARM core is active, the ARM runs the operating system and that takes over control of the board.

The down side to this architecture is that the ARM is nothing very special (not super fast but does have some advanced features like an FPU and a Vector unit) and must share its RAM with the graphics core.

There are some rather nice DSP cores on the chip too, but Broadcom haven't given the Raspi team permission activate them in the firmware (yet!).
