I have had zero issues playing these games on my ROG Ally X. I keep seeing negative reviews for controller issues but I found a video online which shows you how to map the buttons from keyboard to Xbox controller and it got these games working the way they should. That said, it took some patience to get these mapped out the way I wanted but once completed you don't have to worry about this step anymore. Lookup "How To Use A Controller For Mortal Kombat 1, 2 & 3 For GOG" on YouTube and the video takes you through the process step by step. If this game had controller support without the required setup I would have given 5 stars. Well worth the $1.50 I spent during the sale.
