Yeah there's a 99 inventory code in gbatemp made by tomswitch.
I turned it on before opening the divine shard shop menu then turned it off as soon as it opened to prevent other items from becoming 99.
Request for Unicorn Overlord 1.01.
-Infinite Divine Shards.
Tried editing it in Edizon like money, and I can find the value but it doesn't seem to freeze or change value.
