+
+----------------------------------------
+** NOTE **
+ VMU blocks use 
+
+  most case: 
+   - normal saving(nes): 3-9 blocks 
+   - normal saving(fds): 3 blocks 
+   - state saving(nes):  6-20 blocks 
+   - state saving(fds):  66 blocks 
+
+  worst case: (calculated by assuming compression had no effect)
+   - normal saving(nes): 18 blocks (40 blocks if MMC5)
+   - normal saving(fds): 520 blocks
+   - state saving(nes):  96 blocks (240 blocks if MMC5)
+   - state saving(fds):  700 blocks
+
+
+----------------------------------------
+** STATE SAVE NOTE **
+
+About quick state save: 
+ quick-state-save shares savefile with all ROMs. 
+
+ It's cleared when exit game 
+(more exactly, it's cleared when load next ROM. 
+so, remaining the quick state save data, even though you quit game, 
+if you select the same ROM again.)
+
+
+About VMU state save: 
+ VMU-state-save makes a file per ROM. 
+
+ It's saved to VMU, so you can load state after quit NesterDC. 
+
+
+----------------------------------------
+** NOTE **
+ VMU LCD info
+
+ * in main menu
+
+ +--------------+ 
+ | VMU FREE:    |  <- free blocks in VMU. 
+ |  81 BLOCKS   |
