I' useing a E4X and wants to upgrade to EOS version 4.1. I know, 2mb cpu flash is needed, but nobody can tell me, where I could buy. In ebay, i found nothing and emu's support is no longer the best.
I have the complete upgrade kit (part #6853), with EOS 4.62. I upgraded with it E4XTurbo Classic, but I do not need it any more, since I switched to Ultras. If you want it, tell me.
