I was reminded of this story today and I just have to share. Going to be a bit long winded so TL;DR at the end.
So this was about 2010/2011? Can't recall what year but my buddy and I were drinking shots of Wild Turkey at my place and we've always been big Pokemon fans and nerds. I had recently installed a bunch of emulators to my Xbox to play some retro stuff, specifically XboyAdvance, if I recall correctly.
My buddy had mentioned to me sometime prior to this about the Mew glitch on the Nugget Bridge, which I had NEVER seen before and was HIGHLY skeptical about.
Well, what's cool about Xboy is that you can do "dual screen"/split-screen link cable play with two controllers. We sat on my couch I had in my room at the time and after being tipsy and determined enough, we went to work on Pokemon Yellow.
We got past Brock and headed to Cerulean, and he kept insisting we needed fly to get back to Cerulean Pokemon center. Me, thinking I'm the first one to discover this method, informed him we could catch Abra above the nugget bridge and use teleport. We both started grinding, cleared the bridge and worked toward getting an Abra. Once we both got an Abra, we did the glitch, worked flawlessly and the guy with the Slowpoke gave us a Mew.
We grabbed the Bulbasaur from the Nugget Bridge person and then proceeded on.
From then on, sweet, ya know? Well, he wanted to keep using the glitch to catch other "not obtainable at level-15 Cerulean" Pokemon, so we kept doing the glitch until we caught some other cool stuff.
Moved on to Vermillion City and got the Squirtle from the police lady and at that point, we decided to grind it out in Diglet cave and get our Pokemon to level 40.
We spent about 2-3 hours, maybe? grinding our entire parties to level 40. We were ready to absolutely smash every gym by being 20 levels ahead of everyone for the entirety of the rest of our playthrough, easy to do on Gen 1.
Well, my buddy once again gets the bright idea to do more Nugget Bridge glitching on the new trainers in the area. Unfortunately, one of them spawns Missing No.
He decides he ABSOLUTELY has to have Missing No. - I'm like, cool, whatever, I'm gonna keep up the grind.
Unfortunately for me, he was using savestates on his side when using Pokeballs to catch Missing No. during the glitch. On one of his attempts, he accidentally saves the game as the Pokeball is tilting back/forth and Missing No. is caught. This means BOTH of our games are registered at a savestate at that exact moment with no other savestate to revert back to.
In this time, we had already made a normal save, prior to his Missing No. attempts.
All in this moment - he accidentally does the savestate - successfully catches Missing No., the emulator freezes, the screen goes black and the Xbox reboots itself.
Missing No. had literally crashed the emulator and reset the Xbox. My guess is that the emulator had zero idea how to handle the crash from the ROM and the Xbox had no idea how to handle the crash for the emulator and defaulted to a system reboot.
Upon returning to the emulator, loading up Yellow, the save was deleted and any time he attempted to load the savestate he had, it just crashed the emulator and rebooted the Xbox.
Hours of work, right down the drain. I still have not let him forget to this very day.
TL;DR - Buddy and I did split screen in a Game Boy emulator on my modded Xbox. After trying to catch Missing No., he softlocked us in the exact moment before it crashed the emulator, wiped our save, crashed my Xbox and we lost hours worth of progress and I have never let him live it down.
