'particle system' is a rather lose term imo and is actually pretty implementation dependend.
if you search on google you'll find some apis, but i've no idea how good they are. just make your own ps

read the wiki entry to get an idea

1.) How can i detect memoryleaks or what are typical errors made?

use a memory manager. like -> http://www.paulnettle.com/pub/FluidStud ... anager.zip

texture stripping would be another option

would be nice if you could tell us how exactly :)

thx, you got pm.

actually i already have some code (thx tyr) that should load the modules and fix the imports in usermode.

just haven't found the time and a volunteer (with fw 2.x and gta) to test it. wanna volunteer? ;)

maybe you want to take a look at this topic ?

thx for making that clear Jim.

@Ghoti:

hard to say what's exactly going wrong without seeing the whole source. but i'd suggest to read some stuff about the common errors with malloc on the wiki page. it should help you to get an idea what could be going wrong.

Unix Manual Page for free(): If ptr is a null pointer, no action occurs. If a random number is passed to free(), the results are undefined. maybe that's wrong, never looked at the assembly of free(NULL), but if that's wrong someone should change the wiki entry of malloc and a load of other sources.....

at least you can check if the pointer is NULL before calling free. and as far as i know free(NULL) does nothing:

(without knowing the code for "loadImage") it seems like the memory for the struct is dynamically allocated. so you should change the above code to: void freeImage(Image* image) { free(image->data); image->data = NULL; // obsolete free(image...

that code does not set the pointer to NULL after calling free(). so a consecutive call to free(foobar) will crash because foobar is most likely pointing in the wild.

edit: and how is Image defined? are you sure you're not trying to free a pointer to a struct?

no idea what "freeImage" does, but you can't free undefined stuff. so your pointers must at least be initialized with NULL and reset to NULL after freeing. free(NULL) will just generate a NOP and shouldn't affect your code.

educated guess: you're not freeing all of the memory you allocate when either a) loading the menu b) loading the map just check the amount of free memory after load and you'll see which part (menu/game) eats your memory. then go through your allocs and make sure you free them properly before you loa...

can any1 show me how to create and handle button action? coz all the tutorial are in a forever loop to check if user press any key. maybe in a form of interrupt or whatsoever... pspsdk/src/samples/controller/basic that sample has a while loop ;) pspsdk/src/samples/kernel/threadstatus so basically: ...

currently we don't have anything to test, but i'll hook you both up if that changes. thx for the offer and thx for the bug report with the tree, i'll look into that. Also, how secure is your scores file to 'tampering'? well, good question :) there are some checksums to verify the score file wasn't a...

i love the 'award' idea. would be nice to get medals for destryoing 100% of the enemies, etc... and show that in the online scores.

and i like a lot of the other ideas too. definitely some good suggestions, thx again.

Your website (specifically the screenshot new window code (BAAD!) ) does not work in firefox... And I'm moving this to release announcements, since it seems to be the place for it? i'm using firefox 1.5.0.4 and it works quite good. and just move it plz. i just didn't want to start a new thread. @An...

Possible future improvements: 1. More levels (obviously ^_^ ) 2. Multi-player co-op (online co-op would be even better!) 3. More 'Options'/Options upgrade to more powerful versions once max number is reached. 4. Game remembers last name you input, so you don't have to re-type it each time. @2: mult...

fanjita: how about atrac support? i know, loads of work for you, but a lot of games would benefit from atrac support ;)

pixelformat doesn't matter for swizzeling.

more infos can be found in the wiki

My problem was with the general attitude that its ok to encourage others to break the law because it 'only' hurts a faceless entity that it is perceived to have done wrong. And again, who can say that it does indeed break the law/void your warranty if you use homebrew software? If I write an EULA f...

People should grow up and stop suggesting that committing fraud is an acceptable thing to do. It isn't. Blackmailing people to buy a replacement unit by not offering an appropriate repair service or tools to reflash the psp yourself isn't much better imho. And I'm not sure if you could call that fr...

oh, no idea what those could be used four.

hitchhikr wrote:Yeah T4 & T8 make perfect sense but GU_PSM_T16 or GU_PSM_T32 nope (at least for me).

maybe my docs are out of date, but i don't see the modes you're talking about (GU_PSM_T16, GU_PSM_T32)

as far as i know there are only T4 and T8 for indexed textures. so with a clut mode of GU_PSM_8888 and a T8 indexed texture, you're using 1byte indices to reference into a 32bit palette. so 1 pixel is represented by 1byte instead of 4... edit: T8 means 8bits to represent the index, not the color val...

hitchhikr wrote: I fail to see the point behind these 2 texture modes (especially the later one), did i miss something obvious ?

indexed 32bit textures for example take only 1/4 of the size (+ max 256*4 bytes palette data) of a regular 32bit texture.

i'm just wondering how it's possible to encode your own at3 files. i tried that horrible sonic stage software from sony. you can convert your files to atrac3/atrac3plus with .oma ending.
