LuaPlayer Euphoria V2
PSP developer Zack has released LuaPlayer Euphoria V2, its based on the LuaPlayer v0.20 source by Shine. But Zack has made many speed improvements over LuaPlayer .20 – At 222 Mhz LuaPlayer Euphoria V2 can run at 263FPS, at 333Mhz I clocked over 362fps. So its pretty fast!
Version 2 improvements
* Speed increase. Take the below as a reference :
Sample Demo (included in v1 release, blits a 480×272 image and plays a mp3) speed benchmarks :
LuaPlayer Euphoria V1 :
Cpu Speed @222mhz
Performance : 228 FPS.LuaPlayer Euphoria V2 :
Cpu Speed @222mhz
Performance : 263 FPS.* New function :
systemQuit()
Will return to the xmb if called.
What is LuaPlayer Euphoria ?
LuaPlayer Euphoria is a branch of LuaPlayer that is optimized for speed, Whilst staying true to
the ease of use and function names we have all grown to love.
What can it do? What makes it different to the normal LuaPlayer ?
It can display images up to 100%+ faster than
the default LuaPlayer, by automatically swizzling the images as there loaded.
It also features Mp3 support. This is done on the main processor for now. Don’t worry however, this is a optimized mp3Player.
Whilst displaying a 480×272 image and playing a Mp3 file, LuaPlayer Euphoria can achieve
up to 228 FPS (Frames Per Second) running at only 222mhz!. (SEE SAMPLE DEMO FOR PROOF!)
It also features CPU Speed control. Which can be done by the user. So you can set the PSP’s CPU to either : 100, 222, 266 or 333mhz.
Another feature, albeit trivial, is a built in FPS Function. By simply calling “showFPS()” you can see your game/applications
current FPS out of 60 frames. If you want to see its “True” FPS, comment out screen.waitVblankStart and pad = Controls.Read() – as these
cap the framerate to 60.
The last feature (so far) is the ability to properly free images. I don’t know if this worked before but anyway…
Simply call “freeImage(myImage)” (with myImage being the image you want to free) and it will remove the image from memory.
It goes without saying that you should not be displaying the image your trying to free at the time of freeing it.
+ A lot more to come!
It is slim and phat compatible. Should work on 1.0>5.xx firmwares. Should also work
on chickHen.
