Hello again everyone. I have a few quick questions. First of all, can I use mikmod and libmad (wave & mp3 players) in the same program without running into conflicts? If not, what should I do to get them to co-exist? Secondly, can mikmod (the wave player) play multiple sound effects simultaneous...

Well, somehow I fixed it. I looked into my .bashrc file, and under the pspdev export paths section, there was 3 different export path lines. I had copied them there from an earlier installation of pspsdk. However, this website, http://wiki.ps2dev.org/psp:programming_faq only listed one export path l...

would the updateing even touch that file? Here's the contents of that file @echo off C: chdir C:\cygwin\bin bash --login -i And I have a laptop that I installed cygwin/pspsdk into (which means it's the same up to date version as my pc) and it's cygwin.bat file shows the exact same thing as above, an...

Hello everyone, long time no see! I just updated my cygwin installation, and I updated the pspsdk part of the most recent toolchain (20060120 I believe) But now the bash shell puts out this error when I try to compile : command not found Owner@Pavilion1200 ~ $ cd ../../usr/local/pspdev/psp/sdk/My_Ho...

I'm not sure if I'm missing something or what... If I can't run the mp3 functions inside the title_screen function, then shouldn't the blitalphaimagetoscreen function screw up too? Because it works fine. Both the mp3 functions, and the graphics functions are contained within c files, with h files ho...

I guess no one has any clue about what's going wrong?

I've searched these forums for the answer, to no avail... I'm using the mp3 samples from http://www.scriptscribbler.com/psp/ It worked fine when I followed the tutorial, or modified it slightly. But now I'm implementing it into a project, and I run into problems. I'm doing the all of the mp3 stuff i...

don't everybody reply at the same time now...

so can anyone explain to me the bit shifting I would need to do in 8888 mode?

ok, cool

so, how exactly do I change the bit shifting to for use in 8888? Also, does the starting address of vram change any? I just can't double buffer in 8888 right?

Ok, I understand that. What's the use of dividing rgb by 8 in that code? Why not leave that out and only use values from 0-31? Can someone explain why it was decided to have it divide by 8 and use 255 values?

so does anyone know what exactly is wrong with the code above?

Someone else (from here) told me that it was 255 in 5551 mode, and it's been working fine all along...

First off, here is my code for setting up the video mode and what not. void InitializeGraphics(int mode) { sceDisplayGetFrameBuf((void**)&VRAM32, &BUF_WIDTH, &PIXEL_FORMAT, &UNKNOWN); VRAM16 = (u16*) VRAM32; sce...

I know that I probably already know the answer to this question, but unless I ask this question and recieve an educated answer, it's gonna bug me to no end.

I know that 2.0 PSPs can be downgraded to 1.5, is it possible to downgrade to 1.0 instead?

I've finally gotten around to updating to the latest toolchain and updating the installation, and I got a few questions. I downloaded the psptoolchain version 20050906 and unziped the psptoolchain folder into the cygwin\home\owner\ directory Now, I haven't updated anything in quite a while. Do I nee...

Most of what I know was also learned while programming on the GBA...

I always wondered if there were such things as hardware controlled layers and sprites on the psp, like on the gba. I would've asked but I feared it might make me look more like a n00b, lol...

did you include <png.h>
and <zlib.h> (im not sure if you actually need this one or not...)

i typed all of this in with my psp browser! lol

Did you install libpng and zlib via svn?

I've searched through these forums somewhat, but I haven't found anything to help me out.

What are my options to displaying sprites on the psp? And what about tiled graphics? Which sources or librarys should I look at to get started?

Thanks for everyone's help.

I completely missed that! I just glanced at your makefile and thought it was the same as before. Yeah, that fixed it, thanks! By the way, how do you make comments in makefiles, it's the character '@' right? I had a couple more questions, but I can't think of them at the moment. Thanks again for all ...

For others who might have trouble using Jason's code, I thought it might be useful to see as many working implementations of it as possible. I think one working implementation, which works with all pixel formats and all vram start adresses, is better: main.c Makefile I finally got around to impleme...

So do you mean that I should change the way I use sceDisplaySetFramBuf() to your way, and then instead of this; u16 *address=VRAM+&#40;&#40;&#40;&#40;512&#41;*PIXEL_SIZE&#41;*y&#41;+x&#41;; I should have this; u8 *address=VRAM+&#40;&#40;&#40;&#40;512&a...

Ok, I have my own set of simple graphics routines in C for the PSP. They work fine and everything, but there's one thing that completely baffles me. Everyone says that PIXEL_SIZE is always either 2 or 4, depending on the video mode being used. Well, I used 2 for PIXEL_SIZE because of the video mode ...

I could do that if I understood the bit shifting part. ( I do realize that bit shifting is simply rotating a series of bits in one direction or another, such as 00100 turning into 01000 or 00010, I just don't have any expierience in bit shifting)

I was wondering, which of the 5 or so snes emulators released for the psp is the fastest? And is there any specific advantages or disadvantages to certain ones, other than speed?

If this is an inappropriate topic for this forum then tell me and I deeply apoligize.

lol, I told you he knew what he was talking about...lol

I've looked through your source, messed around and expieriemented with it. I even used some of my stuff and tried the same thing. And I confess, this has me dumbfounded as hell! No matter what I do, I can't get text to be saved in the screenshot without being distorted. I can save pixel-drawn images...

Let me see your source code in its current state?

Try including this file.
#include <pspdisplay.h>

And then put this line somewhere at the beginning of main.c.
sceDisplaySetMode(1,SCR_WIDTH,SCR_HEIGHT);

Then do your thing and take the picture. I bet that fixes it.
