Integrating no$gba as a easter egg

[seankang]

I am interested in integrating the no$gba as a easter egg inside my Windows C++ application -- a semi-commercial tool.

However, I need to hide it inside my executable...
Can I get a static lib of this?

Then, I can invoke it from some secret key strokes inside my application, and play some cool handmade game.....

No, there is no static library of No$GBA.

The closest way you can do it is:

* Embed No$GBA as a binary resource item in your executable
* Extract the resource item
* Use CreateProcess to spawn a instance of No$GBA

I think I know how to do steps #1 and #2. But I am not sure how to do #3... Can you post source code sample or references on this?

and.. sorry for asking these questions without researching myself.. (I am short on time before the software gets released)... How does a person build a homebrew game for this emulator? My dream game would look like matrix or quake, where there is some monsters that look like my team mates....

#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <conio.h>

void _tmain( int argc, TCHAR *argv[] )
{
STARTUPINFO si;
PROCESS_INFORMATION pi;
STARTUPINFO sj;
PROCESS_INFORMATION pj;

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

ZeroMemory( &sj, sizeof(sj) );
sj.cb = sizeof(sj);
ZeroMemory( &pj, sizeof(pj) );

// Start the child process p1.exe. Make sure p1.exe is in the
// same folder as current application. Otherwise write the full path in first argument.
if(!CreateProcess(L".\\p1.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, &sj, &pj))
{
printf( "Hello CreateProcess failed (%d)\n", GetLastError() );
getch();
return;
}

// Start child process p2.exe. Make sure p2.exe is in the
// same folder as current application. Otherwise write the full path in first argument.
if(!CreateProcess(L".\\p2.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi))
{
printf( "CreateProcess2 failed (%d)\n", GetLastError() );
getch();
return;
}

// Wait until child processes exit.
WaitForSingleObject( pi.hProcess, INFINITE );
WaitForSingleObject( pj.hProcess, INFINITE );

// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
CloseHandle( pj.hProcess );
CloseHandle( pj.hThread );
getch();
}

There's a example in how to use CreateProcess. You need to however, use the extracted binary path as the argument for the executable in CreateProcess().

How does a person build a homebrew game for this emulator?

I would recommend seeing GBADev for that question.

Not to bicker, but isn't that copyright violation? To my best knowledge, the No$-series is spiritual property of Martin.

[V1ncent]

@Smiley: Its for some kind of integration. Its not the source code, since Martin has that, and he didn't released it yet.

[seankang]

very cool. thanks. I will try this....

and if there is any spiritual issue in doing this.... please let me know.. I will ask "permission" from the appropriate person...

No.
Embedding a EXE inside another EXE is not illegal.

Yeah, I thought the same.
He could use parts of VBA instead, because it's open source.

which part of the GBA is open source? And where is that source ?

[mudlord]

VBA can't be used.

The license is viral, so anything it uses MUST be GPL or GPL compatible.
