GP32 Launch Fxes

[Alessandro]

Hi.
I've took a look at the GP32SDK Api Reference and it seems there's no api to launch another process..

How can I launch another game/app from mine? What I need to do it's a sort of file launcher... any help? or maybe some code? I'm not using the MrMirko's SDK, just the devkitadv.

Thanks in advice,
Alessandro

The only apps you can launch are gxb's. To launch an fxe you first need to convert it back to a gxb then use GpAppExecute (see spiv's site for unfxe code).

 

[Alessandro]

Ok, how can I launch GXBs?

 

[Alessandro]

Ops, you already answered me

I found this in the header files:

int GpAppExecute(char * p_code_ptr, const char * s_path);

but those functions are not documented in the SDK API..

Where can I get the docs for the funcs not in the GP32 SDK API pdf? :huh:

Later,
Alessandro

I have often wondered this myself - it seems that there are a LOT of undocumented functions.

Yep,
I asked for volunteers to build a comprehensive guide, but everybody's busy

If we had a good documentation, I'm sure we could get more from all our projects B)

Later.

p_code_ptr is the gxb size in the first 4 bytes, followed by the actual gxb.
s_path is the full path to the file, excluding the extension.

ulong s = 0;
GpFileGetSize ( thefile, &s );
gxb=(unsigned char *)gp_mem_func.malloc(s+4);
*(unsigned long*)gxb=s;
GpFileRead(fh,gxb+4,s,(ulong*)&n_dummy);
GpAppExecute(gxb,path);

or something like that.

Thanks for the hint, Woogal.
I'm gonna try this as soon as possible ;-)


BTW: Where did you get those infos from

Thanks
Alessandro

hi!
if you still want to know how to launch an fxe, check my website (www.egloo.fr.st), i've uploaded a doc i've made that contain code for launch .fxe files

 

[Alessandro]

Just did it AquaFish

Thanks for your support.
