Hi Guys,
Is there any particular Raspberry Pi to get specifically for Amiga games,
or is it a matter of just getting the one with the fastest possible CPU?
What performance can be expected from them in terms of Amiga game
playability (with a genuine Kickstart file) ?
Is it realistic to emulate a CD32 good enough to play it's games?
Cheers, Art.

When I owned one it wasn't really possible to run Amiga stuff reliably on one. Even using the Turbo (overclocked) mode it still wasn't great.
-
Personally, if its ARM based, I favor an A9 or A15.
The faster the better (and the more cores the better).
-
Does that make it viable for an Amiga games machine though,
considering I have little other interest in it?
What if the emulation was limited to a stock Amiga 500?
-
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?

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?

I only supply my 1.1Ghz with 800mA @ 5V when running on battery... So I guess 4Watts

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 ;)
-
The important thing is that MESA/Nouveau supports the GPU. Than the 600MHZ CPU would be no problem.

With HostGL we could also run 3D AROS games.

Raspberry pi is horribly underpowered for Amiga emulation. I found that it struggled to emulate 8 bit systems. A lot of the emulators are based on older versions with less accurate sound and such to deal with the slower CPU
I would suggest OUYA its much more capable for emulation. Every emulator I have tried so far from the market are spot-on, and seem full speed with good sound. There are no Amiga emulators in the market but I can try and side load one from my S3. I'm sure there will be an official one sooner than later...
Also, don't believe the negative hype about the controller, its not bad at all. People make it sound like as something that came from dealextreme.

OUYA? huh?
That one slipped below my radar.
Not bad.
Nice processor. Could use more memory and expansion.
Has anyone tried to run an alternate Linux OS on it?

I agree, it should have more flash, or better yet, an SD card slot. In addition, more than one (regular sized) USB would have been appreciated.
The I connected a powered usb hub to mine to connect both a usb thumb drive and wireless kb. There is that.
Also. The price for an additional controller is $50 usd, which is too much. It's nice enough, but without vibration or recharge features, that really seems like too much. You probably don't want to chance getting a used controller as you'll probably get one of the kickstarters which were the ones people were complaining about.
I read something about it being able to use ps3 controllers but I think support for that may be game specific.

Ouya is only $100.00 now so its nice and cheap and is supposedly more powerful than Rpi.
I would happily buy a Ouya if PhoenixKonsole or someone could make a good AROS distro for it that made use of its GPU.
I love the Pi. I don't really have anything against it. But the Pi is optimized for low low low power consumption. I have always valued low power consumption. But in my situation any cpu I own will be permanently plugged into a wall outlet. I will never ever ever run anything off of battery power. So I don't need super extreme power conservative-ness. If a computer uses 20 watts that is ok with me cause its plugged into the wall. What this means is that I am happy to buy an ARM powered computer that is faster than Rpi and uses some more electricity.
Here is a graph of Ouya performance vs. Nexus 7 vs Galaxy S4:

If someone has a Ouya vs. Raspberry Pi chart I would like to see it.

[Talking about Ouya] I agree, it should have more flash, or better yet, an SD card slot. In addition, more than one (regular sized) USB would have been appreciated.
What is wrong with connecting a USB external drive dock thingy? Then you can plug in your old 2TB drives forever and ever. Its the most cost effective mass storage option. Why buy expensive flash when you can buy cheap hard drives?
Also. The price for an additional controller is $50 usd, which is too much.
Then use a wireless PS3 controller or a wired Xbox 360 controller. Or some other Bluetooth controller.
It's nice enough, but without vibration
Vibration is evil and should be turned off at all times.
or recharge features,
True but you can use rechargeable batteries.

I fully agree with ChaosLord, all minor points.
I'm more concerned with the lack of an alternate OS and the 1 MB of memory.

The RPi will run XBMC, although the default UI is kind of sluggish just because of all the effects however, The video playback is top notch quality. I understand that you have pick a more basic scheme which is supposed to improve the experience.
I have XBMC loaded on the OUYA as well and have not done much video playing on it to compare the video quality, but the UI responsiveness is night and day different on the two devices.

The OUYA is substantially faster than my US S3, however the international galaxy S3 is more powerful than the one for the USA market.
I think performance wise I read that the RPi is about the same as the original Xbox. I'm guessing OUYA is like 50% of a 360 or PS3

Isn't there more than one version of the S4?
Which is the graph comparing?

yeah, there is the USA international which again is half the number of faster cores....

I use this on my Pi and the UI is very responsive.

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

1080p

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
-
Yep if you just want something to emulate an Amiga either get an OUYA, FPGA Arcade or a good old MiniMiggy
I'm still in two minds about emulation of retro platforms, I guess it's pretty cool but it's still not the same as having the real HW. I've got a feeling that if I brought something like an OUYA for retro gaming that I end up spending most of my time playing newer games on it :)
-
No way!
The only time it can't play 1080p is the some cases when then audio is DTS multi-channel and you are trying to decode it to stereo. You can compensate for that by overclocking. Obviously this is not an issue if you use a hifi that decodes DTS/AC3...
most of the time playing video uses like under 10% CPU :)

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?
-

It sounds like the same philosophy as the A1000!

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.
-

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!).

I historically buy Amigas, and play with them for a while, but later can't
justify having it around, and sell it.
Sooner, or later though, all of the genuine custom chips have got to fail,
and that's that, so we kind of do have to look at emulation at some stage.
A real A500 is tempting, but the extra hardware for LCD monitors,
and real floppy load times.. I'd prefer to cheat this time ;)
Raspberry Pi also sounds like a good platform for a GPS program.
