Thank you, but no really, in fact it was a peace of cake...
I know, I'm aware of it since I bought my N900 in 2009 There is however, in Extras testing, a version which supports more formats ( http://maemo.org/packages/package_in...5+0m5+ogg+mp3/ ), and it didn't uninstall any metapackages or anything on my phone with CSSU stable (someone reported it uninstalls maemo-fremantle-pr or however is this metapackage named) - is it just case of phones with Nokia's PR's?
Sure, I'll take a look at it during this weekend, but I can't promise I'll make it work. If there is desktop OpenGL rendering engine, I will try to port it to OpenGL ES 1.1 (it's easier for me, I hate writing shaders, etc.)
I know, for upstream the patch dould be better - if you are curious, you may take source code of ubuntu package and replace code in all /src/gui/PainterGL/* classes with my code from /src/gui/PainterGLES classes and it will work... So in fact a better and more proper patch would just update functions in src/gui/PainterGL/* classes and change just a few lines in "main.cpp" and "mk/configure" (and "mk/something", i'm sure i edited two or three files from "mk" directory). Anyway, the code with my patch should be compilable on Pandora AFTER replacing all SDL_gles related calls to their version of SDL_opengl ( SDL_gles library is Maemo-only library and there are few functions which would be not available anywhere else).

You changed default rendering engine to SDL anyway? Ok, the OpenGL can be turned on by using "-g" command line option anyway - I hope you didn't change that
Android Lincity required quite heavy rewrite I guess, as it's different language and must use different libraries...

You know, I've in fact just replaced few OpenGL functions with another ones... My process of porting is:
1. Get your source
2. Restore OpenGL you removed earlier
3. Compile on my ubuntu devel machine
4. It worsk with OpenGL => find in code functions which are in OpenGL but not in OpenGL ES (as OpenGL ES is actually a subset of desktop OpenGL functions)
5. Change this function calls to soething OpenGL ES compatible - but testing is still done on desktop PC, as it is much easier and faster to debug than compiling everything in scratchbox and uploading to my phone...
6. When code is using only OpenGL ES compatible functions - move to maemo scratchbox, replace SDL_opengl initialization/deinitialization and buffer swapping with javispedro's SDL_gles ones (it's really a task for 1-2 minutes, javispedro is the hero here) and adjust compile scripts to use "-lSDL_gles -lGLES_CM" instead of "-lopengl32 -lGL" (also task for only few minutes)

In fact, this whole "port" took me about 3-4 hours overall, including messing up with maemo scratchbox and my ubuntu libraries If Armagetron has working OpenGL rendering engine, it shouldn't take much longer than this to make initial port to OpenGL ES...

Sorry if I made any grammar mistakes which made some sentences unreadable, I have slept really little during past few nights.

Anyone else willing to compare cpu usage on their N900 with SDL and OpenGL ES rendering?
