Is my soul silver fake or just glitched?

So I bought Soul Silver on eBay. I’m having fun and get to goldenrod city. I see that Thunderbolt is a TM in the game corner and I’m like: well this’ll be a chore, especially without slots but my flaafy could use it. So I sit down to play and the screen goes black but the music keeps playing. None of the buttons work and I’ve had a similar crash on my platinum. I think: well ok I’ve seen similar stuff before it’s probably just gen 4 being gen 4. It’s old so it ain’t perfect you know? So I try again and this time no sound but it still goes black. Third times the charm and the music is back along with the black screen. When I close my 3Ds the music still plays. It’s like I’ve soft locked it or something. Only the home button seems to let me out. I’ve heard it might mean my game is fake. Especially since it has a gray shell. But my platinum had a gray shell too and the infrared works fine I play with my friend all the time. Does anyone know what’s up? I really need those TMs.

If the cartridge is gray, I’m pretty sure it’s fake, DS cartridges are supposed to be black. To tell if a cartridge is fake first, you can look at the Official Nintendo Seal, if your carts are fake, it will say, Original Nintendo Seal Of Quality instead of Official Nintendo Seal, also those numbers on the back, the black numbers, if it’s they could be crooked, or not aligned properly, and finally, if you look at the green microchip you might see only one number, but theres supposed to be numbers and letters all along the green microchip.I hope this helped, and if you can’t understand these stepshere’sa (Youtube) video all about it.
