I'll be getting my PS3 soon, and I have some questions: What is the best way to set it up? I want both to be able to run Linux, but preferably also test other 'OtherOS'-things. So somehow I want to set it up so that I have the possibility to: A) Boot normal Game OS from HD B) Boot a Linux dist from ...

I guess Sony really, really doesn't want me to buy a PS3. * I was going to buy one at launch. Then I found out that Linux/OtherOS wasn't permitted to access the RSX => I decided to wait. * Then I was going to buy one when the FIFO buffer thing was found, and homebrew could access RSX. Of course they...

I read on some site that the NES emulator written in BD-J didn't work in 2.50 anymore. Technical details were nonexistent though, so I thought I'd ask here - have Sony blocked running BD-J from USB completely in 2.5? That would be totally retarded, I mean, the BD-J stuff runs sandboxed, so why not l...

That really sucks, my interest in picking up a PS3 really dropped now. Even if it still is possible to buy a 2.00 PS3, having to stay at an older firmware is just so impractical since you won't be able to play games or use any of the new FW features like DivX.

Good going Sony...NOT!!!

Very nice. You do indeed seem to be quite accomplished. That's good, but you could have at least looked through the older threads before asking. I found all that info you asked about here and elsewhere without ever asking a single question. Ask questions that are easily answered by looking at older...

Just check out Yet another Playstation Portable Documentation it is incomplete but better than nothing.

Thanks! That was just the kind of document I was looking for, very nice!

Thanks, but I was thinking more PSP-specific information. No, you figure it out using your more general knowledge and looking at available code. This is DEVELOPER level stuff - it you can't learn from hex dumps, you're not ready for it yet. :) Programming the PSP isn't Visual Basic. I don't know wh...

Thanks, but I was thinking more PSP-specific information.

I've tried out some homebrew coding on the PSP (using 'make kxploit' from the toolchain) and placing the in the GAME150 folder on my 3.40OE and it works fine. However, I must confess that I've never really understood the inner workings on how executables work and on which mahcines it works (regardin...

How do I verify which version of the SDK I have, and how do I update it if necessary?

I noticed this strange behavior as well when porting some code that worked fine on PC OpenGL to the PSP, but I just thought that things worked differently on the PSP. A fix that would correct this behavior would be nice indeed! I'm not that familiar with making changes to the SDK though (I just foll...

That is strange, I also thought that GU_SPRITES where supposed to act as billboards. So right now a GU_SPRITE is exactly the same as a normal QUAD?

Thanks chp, excellent answers!

I'm doing my first little tests of the GU. I found some samples, and got things going. However I had some major problems when I started to do dynamic changes to my vertex buffer, some changes never seemed to make it through. After much testing I found out that adding a sceKernelDcacheWritebackAll() ...

This is a great demo (best demo on the PSP platform so far!). I do miss the voice samples from the party version a bit, but the other enhancements of the final are really nice! Interesting technical info btw, I really like to read stuff like that to get an understanding on how things work behinds th...

I managed to finish my first PSP production, a port of an old GP32 demo. http://sdw.webhop.net/gfx/minicrap_psp_big.png Minimalistic Crap Not very good by PSP standards, but I had to start somewhere! :) Anyway, thanks to all here who helped me with various problems, especially Raphael who sorted out...

Alright, looks like I was on the right track then. Thanks for the answers guys!

I'm doing a small demo and I want to load my .mod file (using mikmod). During development I loaded it from "ms0:/music.mod", that is the root of the memstick. However for a release, I want all my data contained in the same folder as the executable. So I tested to put the mod-file in the sa...

I want to play some music (a .mod) using Mikmod. After some futzing around I managed to build the lib, and I can also compile the example application. However: if (!MikMod_InitThreads()) { printf("MikMod thread init failed\n"); &...

Yay! Triple buffered plasma up and running! And there was much rejoicing... :)

Glad I could help with this, as I just know too well how frustrating PSP development can be sometimes. Hope to see some good stuff from you in the future to make up though ;P Aw man, that's some serious pressure you are putting on me! Well, I'll see what I can come up with... :) I'm guessing my 15-...

Exactly how did your code look when you got it to work, I didn't quite get what you meant by "512, 3, 1 (_NEXT)" ?

Raphael - I can't thank you enough for helping me with this! I was just about ready to tear my hair and/or throw the PSP in the wall, but now it seems like it was one of those rare occasions when a bug actually was NOT caused by my code! :D It is really strange though, I wonder how all other program...

OK, now this problem has passed way into bizarro-land! I built with Raphaels code, both makefile and source and I get the SAME PROBLEM! Just black screen! I've uploaded the compiled files here: http://sdw.webhop.net/tmp/test.zip Please someone try them on your PSP and see if you get graphics or not....

OK, I think I've found the problem. The following code demonstrates the problem: unsigned int* frameBuf = (0x40000000 | (0x04000000)); //unsigned int frameBuf[512*272]; int main() { int x,y; SetupCallbacks(); sc...

AAAAAARGHHH!! This is driving me TOTALLY NUTS! I've developed for tons of more or less strange systems (GP32, TI83, C64DTV etc. etc.) and I have never ever been so totally stuck (going on 24 hours now!) with something so basic! How hard can it be to get a god damn framebuffer going? Can't someone pl...

I still just get the black screen. Could you post your entire code, and also your Makefile and I'll see if I can compile it EXACTLY as yours. I'm using the latest toolchain downloaded from ps2dev.org. My makefile looks like this: TARGET = test OBJS = test.o CFLAGS = -O2 -G0 -Wall CXXFLAGS = $&#4...

Thanks for the reply! I gave it a try, but it didn't make any difference - still black screen. If I understand it correctly, the change was to put the framebuffer in videomem instead of main mem, right? I read an article that stated that if you were planning on filling the framebuffer with CPU-calcu...

I've just got my PSP development environment up and running, and I'm trying to do some really basic things like getting a simple framebuffer to work. However the only thing I get is a black screen. Can anyone spot any obvious mistakes: #include <pspkernel.h> #include <pspdisplay.h> PSP_MODULE_INFO&a...
