Is this already 3D hardware accelerated?

You've cut it out of context. I was talking about diagonal buttons not OpenGL ES based GPU emulation.

Just with him saying email Zodttd i was trying to inform him that Zodttd will be working on a n900 version soon anyway.

Sorry i will keep mouth shut.

Send emails to Zod and see if you can motivate him.

He said he had a whole lot of free time so MWeston sent him a pandora (omap3 device, like the n900) and he "couldn’t be bothered to do anything with it".

On the other hand, we could try finding someone else with the brains for it.

I already mentioned a plausible way.
Pete Bernert, who created the SoftGPU implementation, had also created open source OpenGL GPU plugin, and OpenGL 2 GPU plugin.

As OpenGL ES 2 supported by N900 PowerVR is a subset of OpenGL 2, it will be fairly trivial to port this code to N900 (both PCSX and PSX4All, which is PCSX derivative).

If only we could convince Pete to share the plugin source. Or port it to N900.

..........

regarding ZodTTD.
a N900 costs about 500$, right?
So we need 50 people spending 10$.
I would do that, if he promises a 100% working emulator (or nearly 100%).
You can't count on Nokia on that, /me thinks (because it's an emulator^^)

Edit: I will edit this post with an alphabetical order of the names of the ones who are willing to donate some bucks. When we are at 30 I will notify ZodTTD.

OpenGL would be indeed a big improvement, I would give the 10$ for smooth PS1 games no doubt
