// The rest of it is written by Grover.. for anyone to use, and abuse.

this is a definetly good idea. i myself have done this for the ps2. but remember to make sure that the code will work on both psp and pc, you have to make sure that the code can compile into both an exe and a pbp. for example. if you toss a DX call to the windows version, it may work, but will not work under psp.Grover wrote:No probs.. but erm.. it will be just my demo? Its basically a dev tool - so you really need to be able to build it to try your own apps.
Heres the PC exe:
http://users.on.net/~dlannan//Files/PSP/GLVOX.exe
The idea is that you can make your own demos without a PSP.. then when you get access to a V1.0 PSP.. you can build an EBOOT.PBP and run it without modifying your code. BTW close the command window to exit the app. I use the command line window for stdout.. and stderr.. very useful.
BTW there are a few 'known' bugs I have left in the Src.. this source is for everyone to use, but please dont expect me to write your game/demo for you :-)

you can also run the program without the sky, you just got to comment out 2 lines of code.
