Okay, who wants Repton for Perl?
I'd probably make it so you could supply arbitrary PNGs for the sprites, instead of relying on the Beeb format (though of course it would still load those). And I certainly wouldn't be distributing the original maps along with it, because they're copyright. But most of the fun of Repton / Boulderdash / Rocks'n'Diamonds is building your own levels.
