Ultimate 64 - Neue Firmware Releases

  • Firmware 3.10 now available for download!


    Fuer das alte Ultimate 2 Modul gibt es, auf Grund der Speicherknappheit, nun 3 verschiedene Versionen der Firmware:

    update_3.10_au.u2u -> ein Laufwerk und Audio

    update_3.10_dd.u2u -> zwei Floppy Laufwerke

    update_3.10_gm.u2u -> ein Floppy Laufwerk und komplette gmod2 Unterstuetzung (incl. Eeprom)

    Für die 1541 Ultimate II ohne Plus ist dabei leider ein Fehler unterlaufen, die Datei update_3.10_gm.u2u hat fälschlicherweise den selben Inhalt wie die Datei update_3.10_dd.u2u. Die Version der Firmware, welche GMOD2 unterstützt, wird Gideon also nachliefern müssen - ich habe ihn gerade per E-Mail informiert.]

    [Nachtrag 2: Gideon hat soeben eine korrigierte Release hochgeladen.]
