As I walked down the street to my house from school I noticed a shiny rectangular object in the grass. When I investigated I discovered it was a green Game Boy Advanced cartridge with it was in perfect condition. Without thinking I picked it up I walked down the street until I reached my house. The second I went in I went straight to my Game Boy Advance.

I booted up the game and as expected it started up normally. The Title said "Pokémon Prehistoric Emerald". I assumed it was a hacked game, but that was okay, hacked games are fun. I saw that the only option on the game was continue. Aside from continue it showed nothing. I hit continue.

I was at a completely empty room with only one NPC it was the sprite of a professor. I checked my Pokémon, all I had was a Level 100 Celebi with the moves Ancient Power, Cut, Magical Leaf and Recover and the OT was Time, All was normal. My trainers name was apparently Time. According to my trainer card had no poke dollars and no badges. He did however have all Pokémon on his Pokedex. I wandered around, but there was no way to escape. I finally talked to the professor. He asked "Are you ready" then it gave me the option to say yes or no. I said no but nothing happened. I talked to him again but this time I chose yes.

Shortly after I chose yes the screen did the same animation as in the Dimensional Scream in Pokémon Mystery Dungeon. I as in an area witched looked like a desert with tons of tall grass and trees, with no music. I walked into the tall grass, after a little walking I found a shiny level 100 Aerodactyl. I really wanted to catch it

I attacked but then it said "Areodactyl attacked in a grumpy rage". Then, in the over world An Areodactyle Sprite appeared. Then, without hitting anything I ran upward. After running a little bit I finally got to what looked like a group of Basheldon. I ran up to them.
I found out that I can jump over them, just like ledges.

The Areodactyl "flew" over the Basheldon. A few seconds later there was rumbling, like an earthquake. I leaped over the Basheldon. I went upward for a minute only to find an Egg. I interacted with it. It said "This Egg is abandoned, take it? Then I was asked yes or no. I chose yes. I checked my party, as expected, egg. After one step it hatched. It was a Archen. After it hatched, in my party I no longer had my Celebi. Oddly, the Archen was level 100. This was odd because when eggs hatch they are level 5, but I wasn't complaining.

I already concluded I was in the past. So I wandered around until I found some grass. In it I found the same Level 100 Shiny Areodactyl. This time I used my Archen and one hit KO it with Ancient Power. Then in the over world there was the fly animation. Then I was at what appeared to be sky tower. I went upward to find that it was completely normal with the same wild Pokémon. I ran up till I reached the top. Where I found a Rayquaza landing on top the tower. Then it said "I shaped the ozone layer not long ago, which is why all is around. There is more to be done" then it faded away

The game crashed…
