bspfix

(October 14, 2017)

bspfix is a command-line tool for converting Half-Life: Blue Shift maps to the normal Half-Life BSP format and vice versa. When Gearbox released the Blue Shift expansion, a change in format made Half-Life: Blue Shift maps incompatible with map decompilers and other tools created by modders. bspfix converts these so that they may work with modder tools again. If needed, bspfix can also convert normal Half-Life BSPs to the Blue Shift format.

To use bspfix, drag a BSP onto the executable and type y at the Command Prompt. It's recommended that you keep a backup of the original map for safekeeping.

Sample output:
