Interrupts, IRX, just some Questions.

Hi, I had just a few questions. First, before I code anything, I would just like to hear if you think this could be done. I was wanting to run a program in the background during a regular ps2 game. Would it be possible to hook a small amount of code to an interrupt and then launch a ps2 elf and stil...

Some help with SetAlarm()

Hi again, I'm having trouble finding any documentation on the EE's SetAlarm. I'm wondering if when an alarm is set, it will call it's callback function even if there is another thread currently running. Could anyone give me an example of how SetAlarm is used, or at least describe the parameters. Whe...

Thanks pixel,

I hurried the code and I knew that somewhere I would forget to do a few things...

Sorry about the non-unix compliantcy, I did do the compiling under windows.

Thanks for letting me know.

rmalloc uses malloc it is just a wrapper that I used for debugging purposes. It keeps the size of all the memory I allocated with it so that I could see about how much memory my program will use at its peak. You don't even need to use rmalloc.

Unloading an IOP module?

Hi again, I was just wondering if it is possible to unload an IOP module. For example, if I loaded and executed several modules, is it possible to unload one of those while running code from the EE? I am interested in the idea of running ftpd at certain points in my EE program. Parts of the EE progr...

Yes, much of the decoding is done with the help of madlib.

In a few days, I'm going to also release the code for my player,
I just need to unmessify it a little bit :)

Playstation 2 MP3 Player

Hi,

I'm pretty new to the console dev scene, but I've finally finished
my first bit of software. It plays MP3s from CD and HDD.
If you get chance, please test it and leave some feedback.

However, I still cannot use fileXioOpen and fileXioRead, these functions return < 0. Does anyone have any suggestions? static int f...

If I want to use the fileXioOpen, Read, Dread, etc... is there any special initialization that I must do? Which device name should I use rather than &...

Thanks, I understand what you mean. I realized that I wasn't really programming under an OS, so there isn't anything to schedule different threads on a ready queue. Although, this makes me curious to whether there is a way to create a scheduler thread that will sleep for a certain amount of time and...

More thread stuff

Hi, some more problems. I'm running a thread to get the status of a controller. Inside the thread, if I hit UP it will decrease the thread's priority, and DOWN will increase it. After I call the thread, my main goes into a busy waiting look and prints some stuff to the screen to identify that it is ...

Ah, I figured it out. I haven't used threads for the streaming yet, but I did get the file to stream correctly. My problem was that each sample is 2 bytes which is stored in one element of a short array I was treating the short array as it it were an array of 1 byte elements such as a char array. So...
