+
+/* Die PC-Emulation einer MMC / SD-Card ermoeglicht es, am PC dieselben Funktionen zu benutzen, wie bei einer echten
+ * MMC / SD-Card. Als Speichermedium dient hier eine Datei (MMC_EMU_FILE), deren Groesse sich mit MMC_EMU_SIZE in Byte
+ * einstellen laesst. Ist die Datei nicht vorhanden oder derzeit kleiner als MMC_EMU_SIZE, wird sie angelegt bzw.
+ * vergroessert. Achtung, startet man den C-Bot vom Sim aus, liegt die Datei, falls kein absoluter Pfad angegeben wurde, im
+ * Verzeichnis dem ct-Sims, von der Konsole aus gestartet erwartet / erzeugt der Code die Datei im Unterverzeichnis
+ * "Debug-Linux" bzw. "Debug-W32".
+ * Eine sinnvolle (und die derzeit einzig moegliche) Verwendung der Emulation ergibt sich im Zusammenspiel mit dem
+ * Virtual Memory Management fuer MMC. Ein Verhalten kann in diesem Fall immer auf dieselbe Art und Weise Speicher anfordern,
+ * je nach System liegt dieser physisch dann entweder auf einer MMC / SD-Card (MCU) oder in einer Datei (PC). Fuer das
+ * Verhalten ergibt sich kein Unterschied und es kann einfach derselbe Code verwendet werden.
+ * Moechte man die Funktion mmc_fopen() benutzen, also auf FAT16-Dateien zugreifen, so ist zu beachten, dass deren "Dateiname"
+ * in der Datei fuer die Emulation am Anfang eines 512 Byte grossen Blocks steht (denn auf einer echten MMC / SD-Card ezeugt
+ * ein Betriebssystem eine neue Datei immer am Anfang eines Clusters und mmc_fopen() sucht nur dort nach dem "Dateinamen").
+ * Im Moment gibt es noch keine Funktion zum Anlegen einer neuen Datei auf einer echten oder emulierten MMC / SD-Card.
+ * Die Code der Emulation ist voellig symmetrisch zum Code fuer eine echte MMC / SD-Card aufgebaut.
