[rake]

not familiar with the hack itself, so i'm just guessing:

add a reverse field to the gamesessions table which will be set to 1 if minimum score should be used, 0 if max.

PHP Code:

$results = $DB_site->query("SELECT gamename, MIN(score) AS min, MAX(score) as max, reverse FROM gamesessions WHERE ...");

while($result = $DB_site->fetch_array($results))
{
   if($result['reverse'] == 1)
   {
       $personalBest[$bestArray[gamename]] = $result['min'];
   }
   else
   {
       $personalBest[$bestArray[gamename]] = $result['max'];
    }
}
