Hello, I have a PSP fat with 3.40 OE firmware and I'm happy with it, but the problem is that a lot of people are reporting me that MasterBoy for example isn't working (error 80020001: the game could not be started). I'm not sure of what I should tell them... what should I do? Recompile it with a spe...

I've answered your question in your topic at playeradvance.org.

Cool! Is there any source code on how to do this, please? :)

Well, the MIPS CPU has a cache prefetch instruction. You could try using it with inline assembly at the start of certain key functions to make sure the data it needs will be in the cache. The hard part, of course, is deciding where to put it, and what data to prefetch. To be pedantic, you don't hav...

It doesn't help, -Os will produce significantly slower code :(
(I'm using -O3 right now and -O2 does help for "bad builds" but is significantly slower on "good builds")

Hello, I've a very big problem, my project (MasterBoy, an emulator for two consoles) seems to have reached a "critical size". In fact, whatever I modify or add can - and will most likely - make the performance drop by as much as 100%. It's usually about 50%, but it's simply enormous anyway...

I'd like to thank dot_blank again, I can now automatically display a message when the headphones are plugged out. The game is paused, the sound muted, and you can select whether you want to disable sound or keep it playing (on the speaker). That's very cool :-)

This toolchain (as well as cygwin especially) is a royal pain to get working, at least on Windows (never tried on other OS). If you want to begin developping quickly you can always use devkitpro which includes devkitpsp. You can get started very quickly, even on Windows Vista. Basically just install...

You're welcome. I'm glad you could unbrick your psp :)

Maybe you could be playing with light, ambient color or something like this?

LOREK> Ok, now I can answer you precisely ^^ I'm sorry, I'll have to do something more about this PC version, I haven't tested it at all since the 2.0 release (I always use PSPLink, it's a bit more handy). I'll try to fix it and improve a bit for the next release. For now, here is what you can do if...

Oh yesssssssssssssss so cool! I've gotta try this :)
This would make the psp a great audio player for silent rooms if we could pause the audio output when the headphones are accidentially plugged out ;)
Thank you veryyyy much :)

The games themselves work fine on the PSP as EBOOT files, so I am asking: did someone manage to develop using JGE++ and use psplink ? If not, should I use another library ? (any suggestion ? I just want to do a 2D game, but I'd like the engine to use the GU as I'll probably need a few 3D features) ...

Yes, would be great.
Btw do you know if there's a way to know whether the headphones are plugged in or not?

Hmm it's like the first version (OSLib 1.0). What is the problem?
No I'm not pspdonkey. Other people can use the logo if they want because the source is available on my site ;)

Thank you very much! I've done a driver for the OldSchool Library (currently mp3 only). It's composed from simple functions such as init, load file, play, decode, etc. The rest is identical to a normal wave output. #include "oslib.h" #include <pspaudiocodec.h> #include <pspsdk.h> typedef s...

Awe-so-me!
It's very intresting, could you post the code you used to do this please? :)

I played with the same idea some time ago. The only problem with it is the 512x512 texture (and therefore drawbuffer) limitation of the GU. So the best you can get is a 512x512 -> 480x272 smoothing, which doesn't look too promising to be honest. Also, with this you will much more easily hit the fil...

Oh thank you. Now oslGet/SetImagePixel take swizzling in account. This is just a problem for people who are using the old method (raw access to image->data) but they will be warned (in the breaking changes section): if they want their old code to work, just put an oslSetImageAutoSwizzle(0) in the be...

I'm thinking about automatically swizzling images upon loading but I need your advice. You'll have to specify OSL_UNSWIZZLED to make sure it isn't swizzled, else it will be. Does this seem better to you?
Thanks in advance for your opinion

My english is not good, and so my explanations are :p
You'll see what I'm talking about when trying the analog sample :)

The analog stick is.... analog :p that is, not very precise. You have to take in account a minimal treshold. The stick will never be at (0, 0). The weirdest is that it doesn't have a "dead zone", its value depend from the direction you moved it last time, but it should always be in a range...

Cool :)
But does this always need KERNEL mode? I'm wondering how official games do :/

I think you are mixing java objects and C structures (which are completely different)... OSLib is C only, so setting a pointer to NULL won't free the associated memory (of course), it will just... set this pointer to NULL (which is usually a bad idea if your object hasn't been freed first because yo...

Thanks for your support and your bug reports ^^ I'm confused when you are saying that oslLoadImageFile is now case sensitive... there is no reason at all. I'm using sceIoOpen and so on. Maybe fopen (like I was using before) wasn't? But fopen was a wrapper to sceIo anyway. That's something to investi...

FINALLY!!!!!!!! Here it is :) The version 2.00 alpha1. Get it here: http://brunni.dev-fr.org/index.php?page=pspsoft_oslib It's alpha, not definite (some things may change until the final release!), but it's still good for testing ;) Please tell me any problem or suggestion with this version. Thank y...

Release the keys? I don't understand what you want to do...

PSPLink... ;)

8 (0-7)

Hmm... it should be okay... I'll test it when I've got some time. Thanks for the report ;)
