Yeah, sure.
1. Make a FCRAM dump after having visited the shop at least once in Pokemon Shuffle.
2. In the dump, search for the text "ShopItem".
3. Find the offset of the highlighted bit in this image (Search for "ShopItem", in this image the cheat has already been applied):
4. Insert that into the template code, where XXXXXXX is the offset of your shop data:
EXXXXXXX 00000064
D0D001A0 00000000
00000005 D0D001A1
00000000 00000012
D0D001A1 00000000
00000026 D0D001A1
00000000 00000050
D0D001A1 00000000
00000BB8 D0D001A0
00000000 00002710
D0D001A0 00000000
000055F0 D0D001A0
00000000 0000BB80
D0D001A0 00000000
D2000000 00000000
If you want to change more than just the prices shop format is as follows:
"D0D001A0" initializer.
8*ShopEntry {
u32 Price;
u32 Number_Of_Items;
u32 What_Item; //D0D001A[0,1] -- 0 = Coin, 1 = Heart
}
