1) you need to connect your laptop and pi to the same router (in my case i connect them both to my cable modem/router combo unit – laptop via wireless/pi via cable), not directly via an ethernet cable. you CAN do it that way but i think you need a special ethernet cable (‘crossover’). probably easiest to just bring your pi down to the basement :)
2) dreamcast does not support .iso – see https://github.com/RetroPie/RetroPie-setup/wiki/Dreamcast
playstation DOES support .iso apparently – https://github.com/RetroPie/RetroPie-Setup/wiki/playstation-1 (not sure why it’s not working for you – is it lower case .iso?)
3) install the latest retropie SD card image, i suppose? or manually go through each rom directory and delete all the roms via ftp or command line.
ps – your english seems great :)
