Hehe.. yes.. fast it was! Too bad I robbed you of the learning experience with dasm or tass.
At the moment there is no functionality for switching location of the second sid from within the program, although it is of course possible to set it when you compile the program, with separate versions for different mem locations. ...but I am actually sitting right now shaping up the 2sid part of the program a little bit. It was really just a hack on top of everything, so to speak. Not built that way from start. So there are a few quirks that need to be straightened out. One of the things I hope to include is precisely functionality to switch between different memory locations.
