I just redownloaded both Mario Kart GP and GP2 from my backup computer into my HDD, and they both worked good since the first time I booted them up.

Only thing is that GP2 sometimes lags a little bit but that's it, nothing else worth noting.
Quite an impresive milestone, you guys are reaching the 100% compatibility here!
37 games have issues out of 757 from the compatibility list in total! (This means either orange or red marked games in the list)
With the proper calculations...
We have a 95.1123% compatibility with Nintendont!
The only big/popular titles that still have issues are RE Zero and a pair of Sonic games from what I could see.
It is really awesome!
