@node REQUIREMENTS "Requirements"

To run Universal SID Scope (USS) requires you need at least
AmigaOS 3.0, MC68020 and MUI. Well, MUI requirement may sound
weird because the concept is rather simple but I can't remember
how to create programs without MUI :)

You also need SID player using playsid.library. Should work with
@{b}all@{ub} SID players using playsid.library but I have tested only
with HippoPlayer. Should work with the MagiC64 emulator, too.

@node JIGSAW "Internal issues"
Some internal issues are explained here.

        · USS can't detect when you unload SID tune. Solutions would be
          polling playsidbase structure frequently but it is too much code
          for such a small achievement.

        · USS supports localization (since my default MUI source code called
          "RUNKO" supports localization) but I have not attached catalog
          description because I think you don't need localized strings.

        · You may think MUI is inefficient for real time graphics but it is
          not true! Invoking MUIM_Draw method >50 times per second for each
          four displays _separately_ (total >200) takes less than 2% CPU
          time (040/25MHz).

        · Since C64 had only three audio channels you may wonder why there is
          four displays; the fourth display is reserved for samples.
          C64 can play 4-bit samples although there isn't any channel for
          samples. (Samples are played back by triggering C64 volume register.)
          For example, try Great Giana Sisters Intro tune or some Martin Galway
          tunes.
