Re: Attempting to port Minecraft (Client!) to the Raspberry

Have you considered Minetest? minetest.net It needs the Irrlicht engine, but as I am also challenged (With two kids) to get Minecraft up and running, I've just compiled and run the very latest OGLES2 version of the Irrlicht engine and it works a treat. It should (I'll find out tomorrow.. to tired to...

Re: Stereoscopic viewing (3DTV) on Quake3

Alas the stereoscopic code has only been implemented in the Ioquake port, so you would have to build it (or grab a windows binary).

Python shouldn't be that slow, especially for serial comms. Are you trying to do something mental with it?

Re: using the raspberry pi and the Oculus Rift

The rift requires a lot of power considering it needs the game world rendered twice. The raspberry pi isnt really up to the job. On top of that raspberry pi is more suited to loFi graphics due to the limitations so even if you got something running what would be the point if the quality was really ...

Re: using two Pis as one dual-core?

You already have a dual-core device. Your GPU runs in parallel with your CPU (Arm). It does depend on what you want to do, but you can get your GPU to do more than just graphics.

Re: clone sd card?

You can only take your image and put it on the same sized OR BIGGER card. I haven't come across a solution to the opposite yet (I can think how it would work). Now, to get the extra space you can do a number of things. If it's Raspbian, you can run sudo raspi-config and there is a menu option that w...

Re: clone sd card?

I did make a video about this. It assumes you are using Windows to do the "cloning" however.

Action-packed it's not, but I hope it helps. You are very wise to want to clone your card.. I regularly trash the contents on mine.

Stereoscopic viewing (3DTV) on Quake3

Given the reasonable hardware, I figured it shouldn't be too hard to convert some games and more to be suitable for stereoscopic viewing, at least using SBS3D (Side-by-side 3D). As it turns out, since 1999, Quake III Arena has had this functionality and it works a treat (it seems nobody has revisite...

Re: Reboot when running quake

I find that Pis tend to vary. I have one that overclocks up to Fast just fine, but reboots 1 second into playing Quake. The other one, with the exact same power-supply, works fine.

128Mb split (arm128_start.elf) also doesn't use the available memory. As far as I can tell. This is the default start.elf too.

True, but we know what we're talking about. The bulk of users will never see the extra ram. I also noticed that the new start.elf is a 128MB split, instead of 192Mb. I must test that one..

Well, that's a disaster isn't it?

Does this mean that if you have a 512Mb Pi you *must* split the memory 256Mb or above to get the full RAM?

Re: What is the difference between 512mb firmware images?

I'm afraid not, because it depends on what else you want to do with XMBC. On a 256Mb Pi, the 192Mb split (i.e. 192Mb to ARM, 64 to GPU) works fine, but I have been finding that various add-ons don't work well (like the Facebook one), probably because of ARM memory, although I can't tell for sure yet...
