Early Roguelike Collection: rogue5/save.c annotate

annotate rogue5/save.c @ 309:11aeff9acc07

Advanced Rogue 7: ignore file locations in the save file when restoring. The variables file_name, score_file, and home are no longer overwritten with the values stored in the save file. Those values could be inaccurate if the files have been moved or configuration has changed.
