Insert_witty_name would like to be the new project maintainer and I'm glad to handover the project to him! He leads the new development of Lua Player and maybe merging the PS2 development into the main Lua Player, if evilo have no objections.

searching for a new Lua Player project maintainer

I promised the new OpenGL Lua Player for Windows, Mac, PS3 and PSP some time ago, but I'm sorry, I have to work for too many commercial projects at the moment and my interests in my spare time have changed to Lisp and Forth. But I don't want to block further development of Lua Player, which is the r...

If RSX were available for Linux, it would be possible to play cracked games on it, which is impossible, if you don't have access to the hardware which the game needs.

Shine, I'm interested to see the article you have read that says Cg code can be run on RSX from alternate OS. Because Cg code is just another previous form for shader code and GPU power is mainly based on shader code. In other words, if it's true, then there may be no limit at all except the lack o...

The otheros.bld is the boot loader, which needs to be on the same medium when installing the OS from the PS3 game OS. But it is not allowed to put it on the live CD, so you'll need these two st...

Ogg/Vorbis support is a good idea for Lua Player, but I don't like MP3 or UMD access. MP3 has licensing issues ( http://www.mp3licensing.com/ ) and I can't image any legal reason for UMD access.

Lua Player OpenGL for Windows, PSP 1.0/1.5 and PS3

I've started to rewrite Lua Player with the SCons build management and based on OpenGL for all graphics output. For the PSP it uses pspgl, which has some limitations (see #ifdefs in common/LuGL.cpp). I have tested it on a firmware 1.0 and 1.5 PSP, but it doesn't use kernel mode, so it should work wi...

Programming the RSX could be interesting, but if you want to write programs, which many users can use, it is a dead-end, because Sony will fix any bugs with firmware updates and then it's like on the PSP.

Re: Framebuffer hello world and performance measurement

No need to worry: When compiling with -O2, copying the memory with 64 bit access and reordering the access (line-by-line instead of column-by-column) you can do 10 full screen blits with an additional 50 pixel bar overlay in 13 ms :-)

One main advantage currently is that the standard Fedora Core version for the PS3 is only compiled in 32 bit mode, but Gentoo is 64 bit (at least the version which mtb has built).
