Hey y'all!
I started playing through all currently available Mortal Kombat games a couple years ago to see if I could get all the achievements, but I kept running into problems with my MK9 save data either getting corrupted or disappearing on my newer consoles when redownloading my 360 profile for troubleshooting purposes and it getting automatically replaced with an empty cloud save. There's no way I'd get My Kung Fu is Stronger (mastering every character in the roster) naturally under these conditions, so I wound up looking for downloadable save files online
I wound up finding one at this link: https://www.xpgamesaves.com/threads/mortal-kombat-100-complete-save.147096/
The instructions for how to get the achievements to trigger are as thus:
Do one each of the "Test your...".
Perform one X-Ray for the e-X-cellent achievement.
Grab someone once for the The Grappler achievement.
Play one versus match for the Wavenet achievement.
Perform one fatality with any fighter OTHER THAN Reptile for the....My Kung Fu Is Strong achievement and Complet-ality achievement
Perform one fatality with Reptile for the My Kung Fu Is Stronger achievement.
Finish one ladder match for the Where's The Arcade? and Arcade Champion achievements.
Other achievements will pop-up as well!
I used Modio 5 to resign the save file and got it running on my profile after some tinkering. I was able to get all of the achievements listed here (I actually had most of them naturally already), but the 'other achievements' it mentions never wound up popping for me. I figured I'd make a post here in case somebody on this subreddit happens to have had a similar experience and knows exactly what to do, or is just willing to throw out some suggestions. The forums where this file were posted are pretty old and mostly dead, so I don't expect anybody will answer my questions there anytime soon. I don't know if I need to do each of these in the exact order that's listed, or if already having some of the listed achievements prevented some kind of domino effect that requires one achievement to pop before popping the next one in a specific sequence. I know I can always just get the remaining achievements the honest way, but at my current skill level, I'm not confident I could do something like finish all 300 challenges in the challenge tower before I randomly lose all my save data again. Not to mention achievements like getting a jackpot in Test Your Luck or triggering the secret fight against Smoke in the arcade ladder are literally just RNG based and require no skill, so I figure it's not too dishonorable to try to finally complete the game this way
If anybody can suggest anything to try, it would be greatly appreciated!
