According to the
Game Maker Documentation on the GUI, .GB1 backup files may be loaded from the Import tab on the startup screen.
Here's the specific quote:

Import: Here you can load up the compressed *.gmz project files and also import game files created with other versions of GameMaker, including GameMaker 6 (*.gm6), GameMaker 7 and 8 (*.gmk and *.gm81) as well as GameMaker 8.1 (*.gm81) and much older (*.gmd) files. It should be noted, that the older the file type, the less likely they are to run without a lot of rework due to the changes wrought in GameMaker through the years. Additionally, you can load up GameMaker backup files (*.gb1, *.gb2 etc) from this tab too.
