Line 15:
In the Japanese versions of Pokémon Gold and Silver, after the hiragana 'まい' in the dialog "あなたの コイン (n)まい" (your number of coins) appears, a hex:57 control character is used (at offset 0xF9FE, in both versions, and in both revisions v1.0 and v1.1), and it is valid as a terminator in these versions.
The hex:57 character is still used as a terminator for "Coins: (x)" in the English versions (at offset 01985B0), but it is no longer a valid terminator there. The game jumps into memory at echo RAM address E112, which is essentially C112 and executes arbitrary code from there. This section of the memory can be changed by listening to cries, but if the player didn't listen to any cry, it is mainly 00, so 'nothing happens'. <!--I can't find a ret and I found an invalid opcode eventually, why doesn't the game freeze?-->
When the player listens to a certain Pokémon cry before using the Coin Case, the game will execute code that has a noticeable effect, including glitch dimensions, altered number of coins text and freezes, due to the data no longer being mainly 00.
