^ No because I want to edit luaplayer becuase of a problem I have with netlib. And lua player is C. ( I want to use the powerswitch in lua)

[eldiablov]

but you dont know c .... and how long you been working on Halo-EBOOT ? is progress good ?

[pspfreak9]

I quit that.. Thats a old sig I dont no how that happened I had a new onee... Besides it was just gonna be one of those 2D ones. Im working on stick Arena ( the flash game currently) That, has gone pretty far if someone can help me with my C problem Ill probobaly be done with the Alpha next week.

And yes I do know C, but I went over to Lua because of Netlib.

[eldiablov]

stick arena was one of the first games i started work on in lua. It went really well but alas i didn't finish it.

[youresam]

Uh. Just test if the wlan went out, not the power switch. I have already added the powerswitch in lua, but trust me, you dont need it.
Ever though about a random disconnect? Or maybe they push the wlan switch down?

[Glynnder]

yeah but if they disconnect the WLAN how can their psp send out a message to the other people

[pspfreak9]

Exactly if they pull down their WLan Switch then it cant send empty to the gameroom. And if they turn off the PSP that automatically terminates WLAN. But the 1/2 second before shutting of their PSP I can let it send empty.

If you have added it can I download it?

[Mr305]

How do I swizzle PNG's?, without using any extra libraries...
All I use is libpng/zlib & graphics.h/c

from ps2dev

void swizzle_fast(u8* out, const u8* in, unsigned int width, unsigned int height)

Can anyone explain those parameters that need to be passed?

The chance of someone pressing power while waiting for an online game is very slim.

If you have added it can I download it?

No, its part of the ipodmock luaplayer.

[pspfreak9]

Actually SBA doesn't work anymore because of that. I could fix it though by looking at the source. And if it is part of ipodmock can you just tell me which lua file to put it in and what the code is.

And the chances that someone turning off their PSP isnt slim. I your waiting for someone to join, and noone does, most people just power off their PSP.

uh... no. Most people would leave the game -_- .

O noes!! No one is joining!! Ill cut off my PSP because no one is joining 1 game.

wouldnt they just timeout or something similar -_- ...

[BlackShark]

Does any body know were I can find a good GU tutorial?

[slicer4ever]

um jw how do i search a folder for files? and how do i access flash0

Spoiler for in case your wondering y:

i wanna make a program that well allow you to chage themes (if possible,if not say here or if already made then tell me)

[SG57]

slice - Check the SDK samples for flash. As for scanning a directory, read up via googling the 'dirent' library.
-= Double Post =-
BlackShark - Somewhere at psp-programming, there's a thread where someone ported the Nehe OGL tutorials to the GU.

[SWE_PsYcHo]

how do i shut the psp off with C and which librarys do i need to include to do it ?

[jsharrad]

how do i shut the psp off with C and which librarys do i need to include to do it ?

http://psp.jim.sh/pspsdk-doc/psppowe...cede122cab568a

#include <psppower.h> and link -lpsppower

[SWE_PsYcHo]

Thx :d
-= Double Post =-
so is it int scePowerRequestStandby ( void ) that i need ?

[hallo007]

thats not completly off , thats standby

[SWE_PsYcHo]

well i tried with scePowerRequestStandby(); and i included <psppower.h> and i added -lpsppower to LIBS in the makefile but when i try to compile it it says: main.c : In function 'check':
main.c(183) : warning: implicit declaration of function 'scePowerRequestStandby'
-= Double Post =-
and how do i completly shut it off then?

[hallo007]

dunno search some libaris or check the hense sdk

[will1234]

SWE_Psycho update your SDK to fix the implicit declaration. Download the toolchain and do ./toolchain.sh -p

[SWE_PsYcHo]

but i dont got cygwin i got psp sdk

[Mr305]

Good...

[BlackShark]

but i dont got cygwin i got psp sdk

LOL you kinda need cygwin to use the psp sdk :P

[Mr305]

Accidental reply, instead of edit...

hey i was wondering if anyone could help me out with this problem. I followed psp programming.com tuturials to play MP3's in my program but when i compile i get this error

[yaustar]

You have spaces in your PSP_EBOOT_TITLE

PSP_EBOOT_TITLE = MP3 Player Example

Should be:

PSP_EBOOT_TITLE = MP3PlayerExample

Or similar.

[Moca]

You have spaces in your PSP_EBOOT_TITLE

PSP_EBOOT_TITLE = MP3 Player Example

Should be:

PSP_EBOOT_TITLE = MP3PlayerExample

Or similar.

O_o

Never knew that :P

Maybe your talking about

Target = *

meh, spaces work fine for me :P


Mind Explaining why you should not have spaces in the eboot Title :)

[yaustar]

Oops, I misread the output. You are right, you can have spaces in the title.

Correction: You have a trailing space in TARGET

TARGET = mp3

should be

TARGET = mp3

(Yes there is a difference, highlight the line to see the trailing space).

You can see the screw up in the command output:

psp-strip mp3 .elf -o mp3 _strip.elf

Hey everyone. I've just installed cygwin and downloaded the psptoolchain from ps2dev.org. When I go to run it (./toolchain.sh), I get the error: Error: Please make sure you have 'automake' installed. I installed all of web and devel with cygwin. Any ideas for how to fix this? Thanks.
