 Your first compile processes every source file at once. After that, only modified source files have to be reprocessed, so compiling again should be a few seconds faster.

+`make clean` deletes any preprocessed source files (.tx), rgbds object files and the compiled rom, in case something goes wrong.
+
+`make pngs` decompresses any lz files in gfx/ and then exports any graphics files to png.
+
+`make lzs` does the reverse. This is already part of the build process, so modified pngs will automatically be converted to 2bpp and compressed to lz without any additional work.
