rogue4: don't put savefile metadata into the savefile.
The save_file() function in save.c stored the savefile's device number,
inode number, creation time, and modification time in the file. The
restore() function read them back, and apparently used to compare them
to protect against cheaters.
Unfortunately, the types and sizes of these numbers differ from system
to system, which ruins the Roguelike Restoration Project's fine
portability work. So they have been removed from the savefile.
This BREAKS SAVEFILE COMPATIBILITY, but old files can be converted by
excising the chunk starting at offset 0x22 with length sizeof(ino_t) +
sizeof(dev_t) + 2 * sizeof(time_t). That's 0x14 on i686 and 0x20 on
x86_64, at least with current versions of Linux and glibc.

.TH ROGUE 6 .UC .SH NAME rogue \- Exploring The Dungeons of Doom .SH SYNOPSIS .B rogue [ -s ] [ .I save_file ] [ -n .I playername ] .SH DESCRIPTION .PP .I Rogue is a computer fantasy game with a new twist. It is crt oriented and the object of the game is to survive the attacks of various monsters and get a lot of gold, rather than the puzzle solving orientation of most computer fantasy games. .PP To get started you really only need to know two commands. The command .B ? will give you a list of the available commands and the command .B / will identify the things you see on the screen. .PP To win the game (as opposed to merely playing to beat other people's high scores) you must locate the Amulet of Yendor which is somewhere below the 20th level of the dungeon and get it out. Nobody has achieved this yet and if somebody does, they will probably go down in history as a hero among heros. .PP When the game ends, either by your death, when you quit, or if you (by some miracle) manage to win, .I rogue will give you a list of the top-ten scorers. The scoring is based entirely upon how much gold you get. There is a 10% penalty for getting yourself killed. .PP For more detailed directions, read the document .I "A Guide to the Dungeons of Doom." .SH OPTIONS .PP If a .I save_file argument is given, .I rogue will attempt to load a previously saved game from that file. .PP With the .B -n option, .I rogue will load a game with the name .I playername from a location defined at compile time. If no such game exists, it will start one. .PP The .B -s option prints the top-ten scores list and exits. .SH FILES .ta 2i /usr/local/games/roguelike/rogue3.scr Score file .br ~/rogue3.save Default save file .br /usr/local/games/roguelike/rogue3save System savefiles .DT .SH SEE ALSO Michael C. Toy, .I "A Guide to the Dungeons of Doom" .SH BUGS .PP Probably infinite. Currently known bugs are: Sometimes you are still hungry even after you eat food and sometimes you get a monster on the screen in reverse video which may or may not cause a core dump. .SH COPYRIGHT Rogue: Exploring the Dungeons of Doom .br Copyright (C) 1980, 1981 Michael Toy, Ken Arnold and Glenn Wichman .br All rights reserved. .br License: 3-clause BSD, see LICENSE.txt for details.
