Any bug report, critic or advise is welcome and sorry for my really bad english

Good Job It's a great idea for create new plugin
GO FOR MORE FUNCTION

(my english is very bad, sorry )

Wow, great job, Rinnegatamante.

Wow.. waiting for some new apps & games for xmb.

Hey, this is a pretty cool project you should also add USB functions.

This is a pretty interesting project. Keep it up mate

We made quite progress:

dofile/loadfile functions are buggy (on PSVITA, i've not a PSP to test) so i'm working to build a prototype of a new function (System.protodofile) which works like loadbuffer/loadstring which are fully working (The difference between them and System.protodofile is only that my function will accept filename of LUA script).
Actually System.protodofile is instable (few times it crash PSPemu) and it has a limitation: every time it's called, LUA interpreter is restarted (so actually, it's impossible to load module with this function).

Added few functions in order to manage memory of PSP/PSVITA (Kernel.memcmp, Kernel.memset, Kernel.memcpy, Kernel.storeWord) and also new functions on System class (System.doesFileExist, System.isPSP, System.loadModule, System.unassign, System.assign, System.getModel, System.md5sum, System.sha1sum).

New functions list:

Also, i added a check on number of scripts in lpp.prx folder. In order to improve compatibility between future plugins, if there are more then one script on lpp.prx folder, lpp.prx wil load a simple menu where user can select which one to load.

I planned to release a first official alpha when System.protodofile will be fully working.

Finally, i fixxed System.protodofile which now works very good!

I also added Color class in order to simplify print functions (Color.new, Color.getR, Color.getB, Color.getG) and i added System.debugPrintGradient.

As i promised, i release the first public beta of the project (R196 Beta).

New video:

Hey Rinnegatamante, when I press R to launch the plugin, it gives me an error. I'm using a PSP Go, so I load the plugins from the internal storage. (ef0) Also I'm on fw 6.20, don't know if that'll make a difference.

Anyways I had a look, at your sample scripts. I improved your 'pspident' sample, with a few extra functions and making the code more user friendly(That is adding indentation and such). If you wanna use it, I uploaded it on here: https://www.mediafire.com/?qua6b2xk60bagir

Thanks for your work
