+====== SMSR00 Compression ======
+Yoshi's Story uses an LZ77-type compression format called SMSR00 which is very similar to SM64's MIO0 format. In the Yoshi's Story ROM, each SMSR00 block is preceded by a 16-byte 'CMPR' header which contains the size of the encoded block and its destination size.
+===== CMPRHeader struct =====
+<code C>
+struct CMPRHeader
+{
+    /*00*/ char cmprSignature[4]; // 'CMPR'
+    /*04*/ u32  srcSize;          // size of encoded data
+    /*08*/ u32  dstSize;          // size of decoded data
+    /*0C*/ u8   _pad[4];          // structure padding
+};
+</code>
+===== SMSRHeader struct =====
+<code C>
+struct SMSRHeader
+{
+    /*00*/ char smsrSignature[6]; // 'SMSR00'
+    /*06*/ u8   _pad[2];          // structure padding
+    /*08*/ u32  outputSize;       // size of decoded data
+    /*0C*/ u32  dataOffset;       // offset of the data section in the smsr00 block
+};
