# Wrapper script for nevernoid to allow read-only shared data
|
|
# files, plus writable per-user highscore/settings in ~/nevernoid
|
|
# Author: B. Watson (yalhcru@gmail.com)
|
|
|
|
# How lame is this? The game opens the map files O_RDWR (read/write
|
|
# access), even though it never attempts to write to them! Also, it
|
|
# doesn't use fopen() to do this (I tried a LD_PRELOAD to fix it).
|
|
|
|
# Because it's closed-source, I can't fix it, and because of this silliness,
|
|
# the user directory needs to contain a *copy* of all the map files
|
|
# rather than just symlinks to them. Fortunately they're small files.
|
|
|
|
# A proper fix would involve either:
|
|
# - The original author fixing the source and recompiling, or
|
|
# - Someone well-versed in Linux-flavored 80x86 assembly to disassemble
|
|
# the code, find the offending O_RDWR byte, and replace with the value
|
|
# of O_RDONLY. This assumes that the call to open() is a separate call
|
|
# than the one that opens the highscores.dat/options.dat files for
|
|
# writing! This is complicated by the fact that the code was compiled
|
|
# with FreePascal instead of being written in the more familiar C...
