Hey guys, yes I originally. reported the problem. It was actually my four year old son who left the house without picking up the lantern so I told him to go back. I tested it twice and it crashed both times, once with corrupted graphics, second time with just a black screen. I tested the PAL rom and cartridge and couldn't reproduce the issue.
I love the SuperNt so much that I'm skeptical that it can do what it does so well. Anytime I see something weird in a game I think is that a FPGA issue but every other time I check and it's perfectly replicating a real SNES. One example is that weird color change on the second level of the Lion King, start the level the background's blue, then it just changes to yellow/orange but the real game does this!
