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...

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...

of course, go for it

danke

Yeah, i found the rawtoasm in the keylauncher source. I had trouble packing my graphics in using bin2s, so I used this program instead...

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.

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...

Here it is.

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 :)

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.

Thanks alot,

Hi, I found out that my problem was that I didn't have the LIBCDVD v1.15 library. So now that I got that, I am able to read files from the cd using fioOpen and fioRead. However, I still cannot use fileXioOpen and fileXioRead, these functions return < 0. Does anyone have any suggestions? static int f...

Okay, cool. I'm using fileXio for reading from the hard drive, I just wanted to be able to use both drives without having to change the code as much. 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 &...

Hello, its me again I can sucessfully read files from a hard drive, and now i'm working on reading files from the CD drive. I'm running into a few problems. First, is it possible to use the fileXio library with the cd drive? Second, I'm trying the following code. cdSync&#40;0&#41;; fioOpen&a...

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...

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 ...

Hi again, I'm having a problem with threads. What I am doing is creating and starting a thread from main() that will call a routine which in turn will create and start another thread. The first thread from main() will run a function that will open and buffer a sound file. When the buffer is full, th...

Well, either way, I got both the threaded and non-threaded versions
to work :)

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...

thats incorrect code for 2 channels :D I'm trying a mono channel right now, so i can just use the left data for both, I have re-written the algorithm, it works a little better, but once the initial buffer is empty it gets choppy. I can't find anything wrong, but its also late at night. short *sample...

sorry about that, made a few typos samples1 = malloc&#40;800&#41;; scr_printf&#40;"Loading.. "&#41;; //Just some pre-loading fileXioRead&#40;fd, &#40;short*&#41;samples1, 800&#41;; for &#40;readIn = 0; readIn < 800; readIn++&#41; &#123; left&...

Hi again, I'm trying to stream a large PCM audio file from my hard drive. I'm using the SjPCM library to help. My problem is, the sound output is very choppy. I am not sure if it is coming from reading the data from the hard drive, or transferring the data to the right and left audio channels. Here ...

I found part of the solution to my problem: Originally, I have been uploading my ELF file via ftp. for example my program is named TEST.ELF and this program calls JPG.ELF. By default my ps2 calls PS2 Key Launcher upon booting. I configured PS2 Key Launcher to call my TEST.ELF program and then my TES...

Thanks for your replies. I've tried using the sbv-lite library to fix the sif problem, however, it doesn't seem to work, I am still getting the same results as before. // Initialise SifInitRpc&#40;0&#41;; init_scr&#40;&#41;; hddPreparePoweroff&#40;&#41;; hddSetUserPoweroffCal...

hi, I'm pretty new to this, but for the past couple of days I've been trying to load an ELF from a location on my memory card. the location of the program is mc0:/BOOT/SHARED/JPG.ELF I uploaded it there myself. my problem is whenever I call SifLoadElf() it tell me it cannot open this elf file. char ...
