Thanks for some ideas. Here is what I'm using: Amy's Fun-2-3 Adventure http://hol.abime.net/3506
Noddy's Big Adventure http://hol.abime.net/992/screenshot
games Brian the Lion, James Pond 2, Car-Vup, Great Giana Sisters - they identify that game as 'Mario'. Floppy drive is always set to 'turbo', small kids have no patience for some reason. 'Say' program from WorkBench extras was also usable.
