 * RELEASE=1 to compile a release build (optimised, stripped, etc.)

 * STATIC=1 to produce a statically-linked executable (good for Windows builds)

 * JAPANESE=1 to enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation)

-* FIX_BUGS=1 to fix certain bugs (see [src/Bug Fixes.txt](https://github.com/cuckydev/Cave-Story-Engine-2/blob/master/src/Bug%20Fixes.txt))

+* FIX_BUGS=1 to fix certain bugs (see [src/Bug Fixes.txt](src/Bug%20Fixes.txt))

 * WINDOWS=1 to enable Windows-only features like a unique file/taskbar icon, and system font loading (needed for the font setting in Config.dat to do anything)
