    For some strange reason version 2 of Street Smart runs on Pow hardware!

    Emulation by Bryan McPhail, mish@tendril.co.uk


Change Log:

FEB-2003 (AT)

- bug fixes:

    pow37b5yel: incorrect sprite priority
  powj36rc2gre: scrambled Japanese text in cut scenes

Notes:

  Sprite flickerings and pop-up's not fixed. They look more like
  sloppy programming than emulation issues. Also suggest redumping
  sound ROM "dg7", it might be the cause of pow060gre.
