Ahh I see... so setting it to the data of the screen buffer is implied... I thought you had to tell it.

Thanks for clearing that up!

So the big win was using 16BPP and making sure the surfaces all have the same format (doh!). Here is some code for those wondering what I mean: pScreenSurface = SDL_SetVideoMode( 480, 272, 16, SDL_SWSURFACE|SDL_DOUBLEBUF ); pImgSurface = SDL_LoadBMP( "InsertFilename.BMP...

Not really sure on what flags to pass through, In AFKIM I'm passing 0. Based on the readme I don't think passing SDL_HWSURFACE will do anything Video - yes, single 32-bit ABGR framebuffer surface only; SDL will emulate other formats as necessary. No HW accel. No 3D. Looking at the sdl-psp source, i...

It really makes that big of a difference, eh?. Also, you're recommending SWSURFACE over HWSURFACE and don't think DOUBLEBUF makes that big of a diff? Or just correcting my code? :)

So I wrote my recent RPG engine on my Macbook pro using SDL (for faster compilation and testing) and began running it on the PSP last week. I'm noticing some definitely issues and lag when running on the handheld. - The first issue was my fading screen code was "flickering" when using doub...

Doesn't work on macbook pro. Looks like fink isn't up to par with intel yet, but I'll keep trying.

Sorry for the bump, but does anyone know FOR CERTAIN what value the PSP Shell uses to organize the homebrew folders?

I believe that you can't change the mod time of a folder by changing its contents, at least on the PSP. Well I did it by connecting it to my G5 and changing the last modified that way, and the file is STILL not at the top of my list. (Top is still the last one I dragged over...) A simple, kludgy wa...

I don't think utimes is actually implemented cause noone worked out how to use chstat to do it, maybe I will do it at some point in the future :) Of course if you want use sceIoChstat directly, I think you create a SceIoStat structures with the times in it, then call sceIoChstat(file, bitmask) wher...

hmm still no luck. Any suggestions? Something that can do what utimes() does perhaps?

I keep thinking it has to be something simple... maybe a typo since I was coding the whole app in one sitting... My dev machine is in my office, so I can't work on it tonight... I'm hoping it's just something simple... I took a look at the psp headers and maybe utimes isn't set up for use on the PSP...

but I cant find a call that will read more than one line of the text, I have only gotten it to flash the entire text, but only 1 char by 1 char, at the position i set it at, does anyone think they can help? fread()? Or am I mis-understanding the problem? Yeah, I wasn't 100% on what his problem was ...

I might be wrong, but instead just doing something (after opening the file) like: char* line; Couldn't you just do a 2-d array.. something like char** line; or char* line[0]; // instead of using the dual pointers... that way you load each line (one by one) into a larger arry, and the...

Or perhaps somebody has another way to edit the last modified date of a file using straight C? Something just the equivalent of "touch"ing the files... Here's the linux equiv.. doesn't seem to work on my PSP though unfortunately... struct timeval times[2]; int main(...

I was trying to use utimes() to set the last modified date on a file, does this command not work on the PSP? I see we have times.h in the SDK but I keep getting an undefined reference to utimes() even though I'm including the proper headers... Does anyone else have any advice on using utimes() for t...

I tried loading in an image at about 1MB for testing and crashed the PSP.

Is there just a limit on file sizes someplace in libpng? Or would this be an individual limitation within my graphics engine?

Thanks in advance!

I use emacs on my linux machine and XCode on my mac

and like everyone else.. make kxploit ;)

In linux it would probably be "source ~/.bash_profile

Could someone point me in a good direction for setting up some simple double buffering using pg.c? If it's easier to write my own graphics library for double buffering, feel free to point me that way too.. email is framerate AT gmail.com. My project is coming along nicely, so you know I'm not just a...

What is the scrn() command? I haven't seen that yet. Also, as to your question, I learned from reading the docs, asking questions like this, and most importantly, reading other people's code. I've been uploading my code as I work, so if you want to check it out: www.framerate.info/psp/test.zip - sim...
