RasterSoft Retro Ramblings

I am currently in the process of porting my Worm Warrior game to the Didj:

Worm Warrior for the Game Gadget

Once it’s finished it will run on an unmodified Didj.

I had to change from SDL 1.2 to an early version of SDL 1.3 to get it to start up on the Didj. It was probably linking to a missing SDL library on the Didj, I still have to fix the input and hook up the Hekkus Sound System (HSS). I developed a SDL 1.2 backend for HSS, which I hope will work with 1.3, and that the Didj SDL_Audio is hooked up.

Developing on an unmodified Didj is a bit of a challenge, since there is no serial port to display debug messages. I got around that by creating a log file at /Didj/Data. The log file will survive a reboot; which the Didj does when exiting a program.

Here’s a little code dump from my logging routine:

bool	g_bCreated;
 
void logString(const char* _szFormat, ...)
{
    va_list sArgs;
    char szString[256];
 
    va_start(sArgs, _szFormat);
 
    vsprintf(szString, _szFormat, sArgs);
 
    va_end(sArgs);
 
    FILE* pHandle = NULL;
 
    if (false == g_bCreated)
    {
        g_bCreated = true;
 
        pHandle = fopen("/Didj/Data/Log.txt", "w");
    }
 
    else
    {
        pHandle = fopen("/Didj/Data/Log.txt", "a");
    }
 
    if (pHandle != NULL)
    {
        fprintf(pHandle, "%s\n", szString);
 
        fclose(pHandle);
    }
}
