I don't know. I have put this one on my todo last week already, but haven't started yet. Does it really need GLSL or is it optionnal?
Release Neverball & Neverputt

I didn't knew this one. Will try it too.
Awesome that is great to hear. I assume that GLSL means it is not a straight recompile to port ? That glshim would not work?
All I know is from the sourceforge website - sorry.

Trackballs had some major visual glitches (like memory corruption) last time I checked, but generally ran.
There is an ES2 branch of glshim that's almost functional. It would also be good to get Regal working on the Pandora.

Yep. Just saw that. I think it's some heavy use of glPoygonMode(face, GL_LINE) (with some line offset) that do the corruption. I'll see if I can hack something for polygone mode not GL_FILL...
Regal I have compiled it some time ago but never actually used it. It's not plug'n play. You have to modify all header to include Regal.h instead of GL.h, and you have to Init it and creat an EGL context by yourself... But yeah, this one may be a test case.

For Trackball, that was that: Polygon mode set to LINE, but inside glLists of course 
.
I still miss some test case it seems (there are still some square here and there, that came black or go back to right colors), but for a 10 min hack, it's not bad :

Hm. I have (as far as I know) a completely standard firmware, and when I try to start Neverball, I just get a quick blink and then it quits. Do I need an upgraded graphics driver or something?

Uh, nope, it should work. Can you post the /tmp/pndrun_neverball.out file content here?
I will redownload to check that I don't actually have a broken pnd (discovered earlier that I might have space problems on that SD), but then I'll do that, yes.
Eh. User error. "No space left on device", so the resource files didn't fit. Once I cleaned stuff up a bit, everything was alright.

Ok fine. Too many PND to play with
Now I've played it. Very nice! Went pearshaped at level 7, but that was to be expected, I heard (Rebirth).

New build on the repo.
It is faster, and the level 7 is somewhat playable on a gigahertz (still lagging on a CC, but you can pass it).

After a couple of year, here is a new build on the repo!
There is quite a lot to say.
First, it's based on latest sources: 1.6
Thoses sources brought a new renderer and a faster physics engine.
The renderer works fine withe glshim, but trigger 2 bugs with the SGX driver! First, the SGX doesn't always like 1pixel sized texture. So I added a workaound in glsim to have 2pixels sized minimum. The second bug is that the SGX doesn't like doing a textured something if TMU0 is disabled. I hacked the rendering engine to workaround this bug...
Now about the physics engine. It's more or less the same code, but it has been simplified and optimised a bit. But still not enough for the Pandora. As a reference, I used the 2nd levels of the Medium set, and you start at 4~6 fps and quickly drop to 0.3fps (using LiveSystemInfo). So I injected some neon code
and more neon code, and I also optimised some code in glshim too (the Sphere reflexion mapping loop).
and now, that same level start at 30fps (on my Gigahertz model), and never drop below 10fps
Still, on CC and Rebirth (and also on maybe on Gigahertz), remove the Reflexion at least, or some level will be slow (but the GPU is limiting this time, not the physics engine). Some intensive levels on Easy are the 10 and 12 for example.
Build 03

I hope you can now enjoy Neverball on the Pandora!
(and the diff of the sources is on the 1st post)

Still fresh, damnit!
Awesome work, thanks! I did test the old version, but gave up once it got too choppy, so I'll gladly give this a go. Will my old savefiles be usable still?

Serial Porter
It should be yes.

Tested now. For the first test, I was downloading code::blocks in firefox at the same time, and the performance in level 7 of easy mode in neverball was a slideshow, perhaps even worse than it used to be, but neverput was fine as far as I tested. Having completed the download and closed off wifi, neverball easy level 7 ran fine, and I was able to progress to much harder levels - I ended at a level where I couldn't physically pull it off, rather than being frustrated by the framerate.
I wonder though, is it possible to make the nubs more responsive in neverput? I seem to only be able to get two speeds of rotation and while that's better than the d-pad which just gives me fast speed, some of the levels require very accurate aiming which can be quite fiddly even at half speed.

I have to check the mouse input code. Not sure how it works and what can be done there.
