I can't believe I was actually able to find this underground cavern!
I discovered what looked liike an old pirate map in the attic of one of those huts in Rainraster Cliffs, and it actually led somewhere!
But now that I've seen where it leads, I think this might've been a bad idea. This place is scary! Maybe you want to take it from here?
First we have to find the cartridge. This is easy to spot in the room.
After returning to Tinsel Upatree he tells us
Whoa, you found it!
What version is it?
Did you know that many games had multiple versions released? Word is: volume 2 has 2 versions!
You have all three? What a glorious collection!
Tinsel Upatree gives us following additional hint:
1) This feels the same, but different! 2) If it feels like you are going crazy, you probably are! Or maybe, just maybe, you've not yet figured out where the hidden ROM is hiding. 3) I think I may need to get a DIFFerent perspective. 4) I wonder if someone can give me a few pointers to swap.
If we simply play the game, we quickly realise that we won't be let through.
Tinsel Upatree has drawn our attention to the fact that there are probably two different versions. So let's take a look at where the version comes from. By simply trying, we can download both a game0.gb and a game1.gb (Gameboy ROM) from this address.
To be able to play a Gameboy ROM locally, we need an emulator. We use visualboyadvance for this.
When we start both ROMs, we quickly realise that the worlds are built differently.
As we are currently using Windows, we also compare the two ROMs with a Windows HEX Editor, in my case the Hex Editor MX. We can see that there are a few differences.
I determined the positions using trial and error, there may be a better method, I still have to find out. So let's adjust game1.gb as follows:
If we start the game again, we will see a magical portal through which we can enter the target room. If we use the radio, we hear a Morse code.
Let's just use the AI again:
PROMPT: Can you translate this morse code? --. .-.. ----- .-. -.--
ChatGPT: The Morse code --. .-.. ----- .-. -.-- translates to "GL0RY".
And that's our solution as well.
