So, yesterday,, I'm playing Emerald. I made it to the part where Wattson asks you to go to New Mauville and shut off the generator. I do that and I surf to the route to get to Fortree. Everything is good. I had beaten the Mimic circle and various other trainers.
Then, I remember that I had my Liechi berry in the berry pot on Soul Silver. I'm thinking "I don't want to lose my Liechi Berry, I've only got one." So I play Soul Silver, which is already in the DS cart slot. I harvest my new Liechi berries and save the game. Now I'm like, "Now that I have my Liechi Berries, I can go back to Hoenn." The game was starting to get good. After tons and tons of scrambling around lost, I had finally gotten the HM Surf. However, and this is a big however, I can't do that because my game has conveniently erased itself.
At this point, I'm pretty upset. I'm all like, blasted Nintendo! This is why people use emulators! Argghhh! I'm selling this game! I hate it! Arrrgggghhhhh! I quickly take the game out and put it up. Then, I start to thinking. Each time the game has erased itself, I had just finished playing a DS game. I had a theory of what was going on, so I tested it out.
I replayed the game up to the point where you're helplessly abandoned in the back of the moving truck, then I save the game. Next, I played SS and replayed Emerald. Sure enough, the game had erased itself. My verdict: Soul Silver is erasing my game saves in Emerald! Oh, johto, how could you betray me so?
Well, that's it. I really don't feel like playing through the game again, but I guess I'll give it another try some point in time.
