Here's another example of how to use the codetype duke_srg posted in post#1006
Pokémon Shuffle v1.1.0 (U) Items are FREE is shop
I have seen people post their codes , address is between 032522D8 - 03259458 (v1.1.5)
so, I want to search from 03251000 to 0325B000 just to be safe
D3000000 03251000//set START address
C0000000 00000A00//set length to search (A00 * 10) = 0xA000 (03251000 + A000) = 0325B000
50000000 706F6853 //search for SHOP 1st value
50000004 6D657449//search for ITEM 2nd value
DC000000 00000000
0000001C 00000000//first search value + 0x1C is 1st item buy value
00000028 00000000//first search value + 0x28 is 2nd item buy value
00000034 00000000
00000040 00000000
0000004C 00000000
00000058 00000000
00000064 00000000
00000070 00000000
C0000000 00000000
D0000000 00000000
DC000000 00000010//increase each search address by 0x10 (4 times faster than 00000004) if search value is always ends with 0,4,8 or C
D1000000 00000000
It works. Thank you
Pokemon Shuffle US v.1.1.8
Edit: Doesn't work on v.1.1.9 :/
