Hi all,

Does psptoolchain work on a 64-bit Ubuntu installation? Has anyone tried developing PSP on a 64-bit OS?

Thanks

That's exactly what I needed, thank you

Hello, I'm trying to establish the relationship between the older adhoc matching constants and the newer ones (my old code will no longer compile). Can anyone please confirm if my guesses are correct? #define MATCHING_JOINED PSP_ADHOC_MATCHING_EVENT_JOIN #define MATCHING_DISCONNECT PSP_ADHOC_MATCHIN...

That worked better, thanks - with a small modification (export):

Here's what I did to get the toolchain to compile: sudo apt-get install gcc-4.2 sudo rm /usr/bin/gcc /usr/bin/g++ sudo ln -s /usr/bin/gcc-4.2 /usr/bin/gcc sudo ln -s /usr/bin/g++-4.2 /usr/bin/g++ Then run toolchain-sudo. Afterwards, to restore gcc and g++ back to 4.3: sudo rm /usr/bin/gcc /usr/bin/g...

Yeah, I installed gcc 4.2, and 'ln -s'ed gcc and g++ to the 4.2 versions. I'm trying to compile toolchain now - so far so good - I'll post if everything goes well.

Looks like a bug in binutils that is being detected by a new version of GCC (or libssp or whatever) on the host. I'd see if you can disable libssp; either at runtime or when binutils is built. The other solution would be to upgrade pspsdk's binutils port to the latest version, although that might b...

I'm getting an error running psptoolchain: I'm running ubuntu, and I have all the prerequisites (I've also installed toolchain successfully at different times). Any ideas? make[3]: Entering directory `/home/jack/psptoolchain/build/gcc-4.3.1/build-psp/gcc' /home/jack/psptoolchain/build/gcc-4.3.1/buil...

Thanks, everyone

How is the glowing of the objects implemented on the PSP - like the icons and text in the XMB, text in SNES9XTYL, etc...? Normally I would assume that one would have to write the code to determine image's boundaries and generate a "glow" accordingly, but the effect is so common on the PSP,...

Display list in general are just something like an abstraction layer shorcut. I mean: when you issue command to graphic hardware, the CPU has to do a whole lot of conversions to make your commands understandable by "GPU". Once you have a bunch of commands converted, why to do it again eac...

Why is C better for psp than C++ ? (just curious...) Because it is. :P :D What I mean is that many programs are C, not C++. You can't use a C++ library in a C program. Most programmers writing in C don't want to switch to C++ just to use XML. They're using C instead of C++ for a reason, and forcing...

Has anyone tried using display lists (not GU_DIRECT) for 2D graphics? I'm curious as to how well this works. In my experience, I found out that I couldn't store texture rendering (GU_SPRITE) in a display list; and even with simple GU_LINES or GU_POINTS rendering, every now and then I get palette cor...

Thanks!

Hi everyone,
Up until now I've used GU_PSM_T8 textures with a CLUT. I'm wondering if it's possible to use these textures without a CLUT, and if so, how is the value interpreted? Is it simply a grayscale value 0-255, or is there color packing? What about T4?

Thanks

Thanks for the responses, everyone.
Sounds like swizzled textures present the best approach.

Hi, What's the best way to implement font rendering on PSP? I've seen programs write directly to uncached VRAM, as well as using swizzled textures. I personally prefer to use sceGuDrawArray(GU_POINTS), but I haven't seen anyone else do it this way. If you've tested various different methods, it'd be...

Insert_witty_name wrote:sceIoSync() looks likely.

I'm not sure it is. I need a routine that'll flush the contents of a file pointed to by a file descriptor (like fflush, but with a FD). Looks like sceIoSync flushes all the pending writes to a device? Not sure, the documentation doesn't seem to answer this fully.

What's the PSP SDK fsync (unistd.h) equivalent?
Thanks

Thank you. I have a feeling that this (http://wiki.ps2dev.org/psp:memory_map) may be relevant in my case (uncached writes and call lists)[/url]

Has anyone else had issues with turning on optimization (O1 or O2) with PSP-based software? In my case, I get odd palette corruption and issues with VRAM. These tend to go on and off with stupid things like adding a function or two, or removing them.

Hello everyone, I've recently tried to add wifi support to one of my apps, which (in case of fw 1.50) involves starting up my app in kernel mode (the application was originally a user-mode application), then spawning off a user-mode thread to do the usual stuff (setting up callbacks, initting sound,...

Hi All,

Is it possible to have the PSP hardware call a callback whenever data is received over peer-to-peer? Basically, I need to have two PSP's exchange data at will, without having to send/receive with ACK's constantly. Any suggestions?

Thanks

It didn't work, but thanks for the suggestion. I'll post an update if I find out anything else. I've had a similar error previously myself. Try changing your call to sceNetInet to: sceNetInit(128*1024, 42, 4*1024, 42, 4*1024); If that still fails to work and you use psplink, sleep th...

I'm definitely interested. The only thing preventing me from using ME (no pun intended :) ) in any of my projects is the lack of documentation and potential for significant code rewrite.
I'd be more than happy to help, if necessary[/quote]

Hi, I'm having difficulty getting adhoc code running on firmware 3.60. The entire process consists of initializing adhoc, setting up matching, then shutting down. The code works on fw 1.50, but it hangs on 3.60 at the very end - when I call sceNetTerm. Does anyone have any suggestions on what may be...

You're getting the 8002013C error because you still have kernel level calls in your 3.xx user mode app. I assume that the pspAdhocLoadDrivers() function does some kernel level loading of the modules needed, wrap that function in a check for the firmware too. You're right, even though I wasn't using...

Hi, I'm having difficulty running an adhoc application under firmware 3.60 (ideally, I'd like to be able to run this application on any firmware revision >= 2.00). Here are the relevant portions of my makefile: PSP_FW_VERSION=200 LIBS=-lmypsp -lpng -lpspgu -lpspwlan -lpsppower -lz -lm -lc -lpspaudio...

While I don't disagree with you, J.F., I prefer to keep my older PSP at the earlier firmware for sentimental reasons :)

Plus, higher compatibility is always better, no?

Thanks again guys

Hi Insert_witty_name, Thanks very much for the speedy reply. One of my units is actually at 1.50. Does this mean that I need to run in kernel mode for compatibility with both versions (and do things the old-fashioned way)? Your app is still running in kernel mode, change the following line: Thanks, ...
