Is my soulsilver authentic? pls help!!!

So I have been saving money for sometime and I decided to buy soulsilver since I couldnt afford it back n the day.I found a seller on ebay who sold a brand new copy factory sealed in protective sleeve for a very large amount of money.I also made sure that he had 100% positive feedback and checked the other items he was selling nothing seemed suspicious though cause he wasnt selling more than two Pokemon games He generally seemed like a collector of games books comics dvds so I knew there was little chance to get a fake .The game came today and although I checked somethings myself I would like a second opinion from someone more experienced in this matter.Images:https://imgur.com/a/CBjEG49Also if I hold the catridge up against light its has a red transparent colorThats all sorry I am being a bit paranoid but I spend a lot of money on this I would like someone who knows how to spot counterfeit Pokemon games confirm me that I have an authentic copy since you can never be sure with ebay.Sorry to bother and thanks for your time.

After comparing your images with my own Soulsilver cartridge and case, everything seems to check out. The one thing that did stand out was that my case is only in English, yours appears to be in two languages. After looking up images for Soulsilver cases, I did find a few that were laid out like yours in two languages, but not many; it might be something specific to the seller’s area.The actual cartridge is impeccably good. The color’s right, the E rating is proportioned properly, the transparent red when you hold it up the the light is normal, they even got the correct text code on the back and bottom of the front. I’m pretty convinced it’s legit. Just play the game and be wary of game-breaking glitches. I haven’t looked into fake DS cartridges as much as I have fake GBA carts, but fake 3rd Gen games are notorious for corrupting and deleting the player’s save file, especially after defeating the E4. The only other way I can think of to prove its legitimacy is to try migration or PokeTransfer, if you can. I don’t know if Soulsilver will allow you to migrate Pokémon from Gen 3 until you reach Fuschia City, but if you reach that point and it still won’t let you migrate, it’s fake. You should be able to transfer Pokémon from a legit Soulsilver cart to a Gen 5 game at any point in SS’s story, as long as you’ve made it to the Transfer Lab in the Gen 5 game.
