Some years ago, around 2016 I was playing the April Fools version just fine if my memory doesn't fail me.
But after realizing that I had to use the Wiimote I uninstalled that game until just now.
I've downloaded Mario War again from that site, they always has the latest version in their servers.
Again, you still need to register in order to download.
Ok so I got around to individually installing/testing each version (1.3, 1.4, and 1.7) from the scene beta site, and all three versions freeze at the credit screen,
then black screen
which reboots into the system menu. Any thoughts on why this might be happening?
