WHY IS IT SOOOO HARD TO DOWNLOAD SAMURAI WARRIORS 2 EMPIRES??

i thought it would be fun to relive my childhood a bit, back when I was playing bulletstorm, devil may cry 4, far cry 2 and ESPICALLYYY my goated game... Samurai warriors 2 empires but omfg bro.. i didnt grow up on a laptop, my pipeline was 

xbox 360 > nintendo 3ds > samsung tablet > phone (got my 1st phone when i was like... 13ish?)

so i never learned how to work a computer till just last year and I wanted to play Samurai warriors 2 empires randomly but my STUPID brother took apart our 10 FUCKING + year old xbox 360 just so he could use the parts for his computer or sumthing and i was so mad but I still had all the discs n controller 

and so I googled like a typical dumbass "samurai warriors 2 empires download free" and it took me to a not so sketchy site and I clicked download, waited for like 2 hours to download, opened up the game and it says something along the lines of "You need to insert rom disc thingy to get this working bruh" and i search up what that is, and im like ohhh yeah that.. dont got it, so I search up a xbox rom emulator for pc, download it and got hit with "Ur cpu doesnt support avx, you BROKE BUM" and now Im learnign the rom emulator makes the quality shit 

and then some random old comment under samurai warriors empires download site thingy says "If there is a notification "insert DVD-ROM" or something like that, just copy the sw2.exe file in the crack folder then paste it in your game folder." so i didnt even need a rom emulator in the first place and i now im redownloading the orginal thing i downloaded for this game and gonna follow this comments advice to see if it works 

sign... only thing motivating me is the random hot guy on the cover of the disc case... 

anyways.. any other samurai warriors 2 empires fans here????? 

UPDATE: holy fack i got the game up and running bro.. i just got sort out the controller thing cause I need a cord for it LOL
