[mythtv] [PATCH] allow .png for NES screens in mythgame

[Junkie Junk]

Forgive my noobness, but I think I have a solution to adding .png 
support for NES, the following is a modified nesrominfo.cpp, please tell 
me if I did anything wrong (and what's wrong with it).
#include <iostream>
#include <qfile.h>
#include <qsqldatabase.h>
#include "nesrominfo.h"

bool NesRomInfo::FindImage(QString type, QString* result)
{
    bool retval = false;

    if (type != "screenshot")
        return false;
   
    // Try to match the GoodNES name against the title table in order to 
get an image
    // index that hopefully matches up with the game.
   
    QString thequery;
    thequery = QString("SELECT screenshot, description FROM nestitle WHERE "
                       "MATCH(description) AGAINST 
('%1');").arg(Gamename());
   
    QSqlDatabase* db = QSqlDatabase::database();
    QSqlQuery query = db->exec(thequery);
    if (query.isActive() && query.numRowsAffected() > 0)
    {
        // Take first entry since that will be the most relevant match.
        query.first();
        QString current = query.value(0).toString();
        *result = gContext->GetSetting("NesScreensLocation") + "/" + 
current + ".gif";
        retval = QFile::exists(*result);
        if (!retval)
        {
            // Look for file with the same name as the Game
            current = query.value(1).toString();
            *result = gContext->GetSetting("NesScreensLocation") + "/" + 
current + ".gif";
            retval = QFile::exists(*result);
        }
        else if (!retval)
        {
            // Look for file with the same name as the Game (png)
   //not sure this is needed:            current = 
query.value(1).toString();
            *result = gContext->GetSetting("NesScreensLocation") + "/" + 
current + ".png";
            retval = QFile::exists(*result);
        }
        else if (!retval)
        {
            // Now just try to match the game name
            *result = gContext->GetSetting("NesScreensLocation") + "/" + 
Gamename() + ".gif";
            retval = QFile::exists(*result);
        }
        else if (!retval)
        {
            // Now just try to match the game name
            *result = gContext->GetSetting("NesScreensLocation") + "/" + 
Romname() + ".gif";
            retval = QFile::exists(*result);
        }
    }

    return retval;
}
