+Random treasure dig-up by shovel by Conn
+
+Apply on any hacked or native ALTTP (US).
+
+
+
+(1) nop out restriction to only collect treasures in field:
+03/A3B2: ad fc 03 f0 04 -> ea ea ea ea ea (check if treasure hunt game is on)
+0e/fd65: b0 28 -> ea ea (check if you are in field coordinates)
+
+(2) disable random HC-piece dig-up:
+0E/FD7A: 90 FD -> 8F FD
+** you need to place this HC via HM to another location, since it isn't available anymore
+
+(3) explanation how to alter the dig-up treasures; not part of hack...
+every time you dig there is calculated a randomized Y-value which determines whether you find treasure or not.
+There are 8 possibilities. 
+Note: Only 4 treasures are alterable with the table, the rest is nothing
+
+pointer table:
+0E/FD72: 8A FD - get treasure
+0E/FD74: 8A FD - get treasure
+0E/FD76: 8A FD - get treasure
+0E/FD78: 8A FD - get treasure
+0E/FD7A: 8F FD - nothing - Before it was 90 FD: get Heart Piece; if 90 FD code will check if you already collected, if yes, you get nothing
+0E/FD7C: 8F FD - nothing
+0E/FD7E: 8F FD - nothing
+0E/FD80: 8F FD - nothing
+
+if you get pointed to a treasure (8A FD), the Y determines which one you get.
+
+Treasure table:
+0e/fd86: DB - 20 ruppees
+0e/fd87: DA - 5 ruppees
+0e/fd88: D9 - 1 ruppee
+0e/fd89: DF - small magic
+
+Treasure Key:
+D8: heart
+D9: 1 ruppee
+DA: 5 ruppees
+DB: 20 ruppees
+DC: 1 bomb
+DD: 4 bombs
+DE: 8 bombs
+DF: small magic
+E0: large magic
+E1: 5 arrows
+E2: 10 arrows
+E3: fairy
+E4... small dungeon, key, big key, sprites, other nonsense...

+Parallel Worlds add-on patch by Conn
+
+Get shovel in menu instead of empty space (patch changes empty space used for bottle content to get shovel there) 
+
+Bottle content is saved to unused 7E/D100, and 7E/D101 is used to check whether bottle is equipped 
+
+Apply on Parallel Worlds-prepatched ALTTP.
+
+
+Still needs to be done:
+- The current version (1.1) does not have a shovel, you must place it in a chest via Hyrule Magic
+- Hide some treasures to dig up ;) 
+
+
+ips for rom without header (Parallel_Worlds_shovel.ips) 
+or for rom with header (Parallel_Worlds_shovel_header.ips)

+06/e168: 8f 4f f3 7E -> 8f 00 d1 7e (think this is run when you receive a bottle)
