Hacking Help compiling a boot.dol

[zantzue]

Hi! Here's a code I found on the Internet (credits go to giantpune):
CODE//super complicated channel loader- giantpune
#include
#include
//#include
#include

#define TITLE_ID(x,y) (((u64)(x) viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

//if you want to put a splash screen, put it here, but it will just be a waste of time. the splash in the forwarder
//is only showed while loading dols into memory, this would be shown before the channel even started to load
//so i wouldn't do it.

WII_Initialize();
//just change the 4A4F4449 to the hex value for the ID4 of the title to boot.
//all channels that show up on the system menu should be 00010001
WII_LaunchTitle(TITLE_ID(0x00010001,0x4A4F4449));

//should not reach this point if the title is installed on the wii, but if it does, it will fall back on a stub to direct it
//if using a newer version of libogc, exit(0) returns the system menu if no stub is found.
exit (0);

//really, really should never make it this far. if it does, the wii will just blackscreen and need a hard reset
return 0;
}
I compiled it and it worked properly; it launches new HBC from NAND. The thing is that I want to change that code so that it looks for new HBC but if it doesn't find it, looks for JODI and HAXX. Here's what I changed:
CODE#include
#include
//#include
#include


#define TITLE_ID(x,y) (((u64)(x) viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

WII_Initialize();
printf("Launching Homebrew Channel 1.0.7/1.0.8");
WII_LaunchTitle(TITLE_ID(0x00010001,0xAF1BF516));
If (WII_LaunchTitle(TITLE_ID(0x00010001,0xAF1BF516))

i cant code but just looking at this seems to me it would be talking about this line

if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

its saying IF this - but nothing there after it

That should work
It's the same as
CODEif(rmode->viTVMode&VI_NON_INTERLACE) {
ÂÂÂÂVIDEO_WaitVSync();
}

Something I noticed myself is that there's a Capitalized if. I believe C is Capital sensitive, so try changing that.

No, there's something after that "if" :

if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

the problem is located here :
QUOTEIf (WII_LaunchTitle(TITLE_ID(0x00010001,0xAF1BF516))

The problem was that I wrote "IF" instead of "if"

. Now it compiles but It doesn't do what I want. I think the probem is "if WII_LaunchTitle(TITLE_ID(0x00010001,0x48415858))[/b]0)" instead of "if WII_LaunchTitle(TITLE_ID(0x00010001,0x48415858))

I am not sure why you call WII_LaunchTitle two times for each of HBC version. Another bug perhaps is that you use
0x48415858 as JODI but this is actually HAXX.

There is almost a similar goal in the sys.cpp code (taken from usbloadergx) that perhaps could help you trying, but
without those printf statements (you could re-add them if you want):

#define HBC_HAXX 0x0001000148415858LL
#define HBC_JODI 0x000100014A4F4449LL
#define HBC_1_0_7 0x00010001AF1BF516LL

WII_Initialize();

int ret = WII_LaunchTitle(HBC_1_0_7);
if(ret < 0)
WII_LaunchTitle(HBC_JODI);
if(ret < 0)
WII_LaunchTitle(HBC_HAXX);

 

[FIX94]

I'm sure you can simply do it like that:

ÂÂÂÂWII_LaunchTitle(TITLE_ID(0x00010001,0XAF1BF516));
ÂÂÂÂWII_LaunchTitle(TITLE_ID(0x00010001,0x48415858));
ÂÂÂÂWII_LaunchTitle(TITLE_ID(0x00010001,0x4A4F4449));

If you also want to display text you will need to do it like this:

Spoiler

CODE//super complicated channel loader- giantpune
#include
#include
#include

#define TITLE_ID(x,y) (((u64)(x) viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

//this is needed to display text correctly
int x = 24, y = 32, w, h;
w = rmode->fbWidth - (32);
h = rmode->xfbHeight - (48);
CON_InitEx(rmode, x, y, w, h);
VIDEO_ClearFrameBuffer(rmode, xfb, COLOR_BLACK);
ÂÂÂÂ
//if you want to put a splash screen, put it here, but it will just be a waste of time. the splash in the forwarder
//is only showed while loading dols into memory, this would be shown before the channel even started to load
//so i wouldn't do it.

WII_Initialize();

//just change the 4A4F4449 to the hex value for the ID4 of the title to boot.
//all channels that show up on the system menu should be 00010001

//HBC 1.0.7+
printf("Launching Homebrew Channel 1.0.7+");
WII_LaunchTitle(TITLE_ID(0x00010001,0XAF1BF516));
printf("Homebrew Channel 1.0.7+ not found");

//HBC JODI
printf("Launching Homebrew Channel JODI");
WII_LaunchTitle(TITLE_ID(0x00010001,0x4A4F4449));
printf("Homebrew Channel JODI not found");
ÂÂÂÂ
//HBC HAXX
printf("Launching Homebrew Channel HAXX");
WII_LaunchTitle(TITLE_ID(0x00010001,0x48415858));

//should not reach this point if the title is installed on the wii, but if it does, it will fall back on a stub to direct it
//if using a newer version of libogc, exit(0) returns the system menu if no stub is found.
exit (0);

//really, really should never make it this far. if it does, the wii will just blackscreen and need a hard reset
return 0;
}

I have not tested it yet but I'm sure it will work fine!

@FIX94 It seems to work. I launched the boot.dol from HAXX HBC. It should have launched JODI HBC but it didn't (I have both installed on my Wii). But that's normal as I switched channels' IDs by mistake. I used 0x48415858 as JODI but that's actually HAXX and viceversa. Thank you for compiling it and pointing me in the right direction: there's no need for "if" sentences. I compiled the code of your last post and it seems to work properly. Displays text and it launches the HBC is installed on the Wii. Thank you very much indeed!

@conanac hopefully you realized of the ID istake. I didn't finally try the changes you suggest as the code FIX94 gave me works perfectly but I do much appreciate your help.

Now I'm trying to figure out how to use delay function...
EDIT: I´m using
CODEtime_t start_time, cur_time;

ÂÂÂÂÂÂÂÂ time(&start_time);
ÂÂÂÂÂÂÂÂ do
ÂÂÂÂÂÂÂÂ {
ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ time(&cur_time);
ÂÂÂÂÂÂÂÂ }
ÂÂÂÂÂÂÂÂ while((cur_time - start_time) < 10);
It works. Now I'm trying to make the boot.dol to write the text in different lines...

You could use usleep, I think that's the easiest way:

//HBC 1.0.7+
printf("Launching Homebrew Channel 1.0.7+");
usleep(1000000);
WII_LaunchTitle(TITLE_ID(0x00010001,0XAF1BF516));
printf("Homebrew Channel 1.0.7+ not found");

//HBC JODI
printf("Launching Homebrew Channel JODI");
sleep(1000000);
WII_LaunchTitle(TITLE_ID(0x00010001,0x4A4F4449));
printf("Homebrew Channel JODI not found");

//HBC HAXX
printf("Launching Homebrew Channel HAXX");
sleep(1000000);
WII_LaunchTitle(TITLE_ID(0x00010001,0x48415858));

edit:
Oh and you need to include another file:
CODE#include

Here is a compiled version:

Please say me if it works!

I agree with you. "usleep" is easier to use. Thank you! Ah, and I discovered how to create a new line by using "\n".

How do I compile this code? What do I need? There's no makefile. I'm a newbie so type slow...ha. And if I want to point it to another channel and I have the ID number how would I do that also?
