-// of 0x400, the last chunk will have size 0x400, and the client will never
-// consider the download complete since it only checks if the last chunk has
-// size < 0x400; it does not check if all expected bytes have been received.
-// To work around this, newserv appends an extra zero byte if the quest file's
-// size is a multiple of 0x400; this byte will be ignored since the PRS
-// decompression algorithm contains a stop command, so it will never read it.
