Hello, I've just received my Everdrive N8 (Famicom version, OS v9.1), but when I tried to run it with my square button Famicom (sbF), it kept getting stuck at startup, sometimes displaying blue, or orange, blue-grey or grey. I then tried to run it on a regular (but still early, with a plastic cart slot) Famicom and it worked! The games load properly and are fully playable, no issues at all. I then put the cart back in the sbF and it now kind of displays the Everdrive menu, but with weird graphics. I tried pressing down and start to try booting a game but it doesn't work, it's stuck in the glitchy menu, so it's probably not a video signal issue (I'm using 80's freak av mod for both Famcioms btw). I should also point out that official cartridges, including the FDS RAM Adapter, still work as usual on the sbF. Here are pictures of both Famicoms after booting the ED N8: sbF: regular Famicom: I tried reflowing the sbF's cartridge port but it didn't change anything. Do you have any idea where the problem might come from?
