Entrypoint is unusable

[Kirbeast]

When I install some dols, I can install them just fine, then when I try to boot installed file I get the error Entrypoint is unusable!. The dol was created with WIICRAZY's WIIGSC tool, here is the dol I'm trying to install

Maybe I didn't have the most updated Priiloader, because of the update in oct 2017

I tried doing a clean install already, I got Priiloader from the tool ModMii, maybe that source priiloader got messed up somehow. If you give me the latest version I will glady test it on my own Wii if you would like. I would also like to know how to add titleIDs, I know how to compile programs with programmers notepad, but I can't get it to compile its a possibility that it is my version of devkitpro

[Kirbeast]

Also after I try to load the installed file and get the error, it breaks going to the Homebrew channel and basically everything else

[Kirbeast]

I tried it on version 0.7 r142 ios 236 mod version and booting the installed file works

[Kirbeast]

Also when I try to load the binary it says failed to load binary

[DacoTaco]

its entrypoint is not compatible with priiloader, even trying to load that file would crash priiloader as its overwriting priiloader. thats why you get the entrypoint error. get the dol to be kickstarted or loaded into a different memory region.

also, i dont know what this "236 mod" is, but i dislike its name already. please use the official release found on wiibrew

[Kirbeast]

Thank you for responding, that makes sense, I will use the latest version of Priiloader, sorry that I bothered you. Can I use doltool.exe to change the entry point address? How do I edit the entrypoint/memory reigon? Maybe a Hex editor?

[DacoTaco]

i dont think hex editing the entrypoint will make the program work. however, using a forwarder or kickstarter might work. included to this comment should be a link to some source code that shows how thats done (and can also be used to load your dol if you compile it with your dol included). the source is found in kickstart\source

good luck! (or, if youre thinkering with that code, add a kickstarter to priiloader that runs in mem2 and starts an executable in mem1. pretty sure thats how HBC does it)

Okay, I don't know what to do with these files, what program do I use? How or what files I'm I supposed to open to use? I'm guessing I use Microsoft Visual Studio code, Programmers Notepad? I just don't understand what I have to do, how do I compile it? Do I need git? I have very basic low level understanding of this stuff, do I run the command Make in command prompt? Does the folder need to be in a certain dirrectory

[Kirbeast]

Okay I changed the directories to match my computer and now it will build with Programmers notepad, now I just have to figure out what to build and where to put my dol, so I open kickstart.vcproj in programmers notepad, clean and then make. Where does my dol go? Do I need to name it something? Oh do I need it to be bin format in data folder

[Kirbeast]

So I put my dols binary in the data folder and named it swiss, then ran make in Programmers notepad, then this is the output I get, did I do it correctly? Do I need to listen to the warnings warning: implicit declaration of function 'memalign' [-Wimplicit-function-declaration] > "make" make -f Makefile.gc make[1]: Entering directory '/opt/devkitpro/Projects/kickstart/kickstart' swiss.bin bin2s -a 32 /opt/devkitpro/Projects/kickstart/kickstart/data/swiss.bin | powerpc-eabi-as -o swiss.bin.o echo "extern const u8"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )"_end[];" >(echo swiss.bin | tr . ).h echo "extern const u8"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )"[];" >>(echo swiss.bin | tr . ).h echo "extern const u32"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )_size";" >>(echo swiss.bin | tr . _).h main.cpp C:/devkitPro/Projects/kickstart/kickstart/source/main.cpp: In function 's8 BootDolFromFat(FILE*, __argv*)': C:/devkitPro/Projects/kickstart/kickstart/source/main.cpp:93:14: warning: 'entrypoint' may be used uninitialized in this function [-Wmaybe-uninitialized] entrypoint(); ^ dvd.c C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c: In function 'DVDCleanUp': C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:97:3: warning: implicit declaration of function 'IOS_Close' [-Wimplicit-function-declaration] IOS_Close(di_fd); ^~~~~~~~~ C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c: In function 'DVD_DoCommand': C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:133:11: warning: implicit declaration of function 'IOS_Open' [-Wimplicit-function-declaration] di_fd = IOS_Open("/dev/di",0); ^~~~~~~~ C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:137:17: warning: implicit declaration of function 'memalign' [-Wimplicit-function-declaration] inbuf = (u8*)memalign( 32, 0x20 ); ^~~~~~~~ C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:161:4: warning: implicit declaration of function 'IOS_Ioctl' [-Wimplicit-function-declaration] IOS_Ioctl( di_fd, command, inbuf, 0x20, outbuf, 0x20); ^~~~~~~~~ C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:168:4: warning: implicit declaration of function 'IOS_IoctlAsync' [-Wimplicit-function-declaration] IOS_IoctlAsync( di_fd, command, inbuf, 0x20, outbuf, 0x20, SetDriveState, NULL); ^~~~~~~~~~~~~~ linking ... kickstart_GC.elf output ... kickstart_GC.dol make[1]: Leaving directory '/opt/devkitpro/Projects/kickstart/kickstart' make -f Makefile.wii make[1]: Entering directory '/opt/devkitpro/Projects/kickstart/kickstart' swiss.bin bin2s -a 32 /opt/devkitpro/Projects/kickstart/kickstart/data/swiss.bin | powerpc-eabi-as -o swiss.bin.o echo "extern const u8"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )"_end[];" >(echo swiss.bin | tr . ).h echo "extern const u8"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )"[];" >>(echo swiss.bin | tr . ).h echo "extern const u32"(echo swiss.bin | sed -e 's/^([0-9])/\1/' | tr . )_size";" >>(echo swiss.bin | tr . _)`.h main.cpp C:/devkitPro/Projects/kickstart/kickstart/source/main.cpp: In function 's8 BootDolFromFat(FILE, __argv)': C:/devkitPro/Projects/kickstart/kickstart/source/main.cpp:93:14: warning: 'entrypoint' may be used uninitialized in this function [-Wmaybe-uninitialized] entrypoint(); ^ dvd.c C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c: In function 'DVD_DoCommand': C:/devkitPro/Projects/kickstart/kickstart/source/dvd.c:137:17: warning: implicit declaration of function 'memalign' [-Wimplicit-function-declaration] inbuf = (u8*)memalign( 32, 0x20 ); ^~~~ linking ... kickstart_WII.elf output ... kickstart_WII.dol

It didn't work failed to load binary

[DacoTaco]

looks likt eht build succeeded then. try starting the kickstart_wii.dol from priiloader and see if it works (it should)

[Kirbeast]

It still throws an error entrypoint is unusable if I try to load its binary it says failed to load binary. Also doesn't work in Homebrew. Maybe I didn't convert it to a binary file correctly, this is what I ran in doltool.exe cmd doltool.exe -b 249boot.dol

[DacoTaco]

mind sharing the kickstart_wii.dol ? i just realised i might have made a mistake xD

how fast do you want a fix for this? cause i have some personal programming i need doing first but ive always wanted to know if it was possible to load a dol from MEM2... :')

[Kirbeast]

Oof, yeah I'll share it, I would like a fix as soon as possible, so the wii has two memory places interesting. Thanks for your help, this will help out a lot of people.

Hey, I’m just checking in, how’s it coming along? Anything I can do to help?

[Kirbeast]

I figured out a patch for my loader, I made a forwarder for my app with ModMii, The forwarder works with Priiloader autoboot, then I put the forwarder in my apps folder as a boot.dol, and converted my app to a boot.elf, homebrew and Priiloader look for the boot.dol before the boot.elf, so it is like the forwarder is not even there.

[DacoTaco]

sorry for the late response,

but do you mind resharing the dol of the actual application?

with the recent changes in homebrew loading for version 0.9 ive been looking at issues with homebrew loading & entrypoints and seeing if much will change. maybe it'll load with the new version (im going to test it too)
