What could be interesting is a game where you're allowed to design races with no points limit at all. . .

StarsRace.pl will pull that data out for you. I did just give a try to reading a race in, and then pushing it back out without changing it. That I can do. But I'm corrupting the file somewhere when I change other bytes in it. I recall I can't change the password in a .r file either even though I can reset it in .m, .hst, and .x files. I think it's tied to the same thing that causes race file corruption. Sorry. After I change a .r file in any way stars reports it as corrupt.
