Hi, love the emulator! Just wanted to report an issue I have with the latest stable version. If my resolution is set at 3840 x 2160 jzintv seems to lock up upon launching a game. Sometimes I"ll get an all green screen or black screen and no sounds or response. If I keep hitting F1 over and over it will eventually quit. Switching to 1920x1080 and the issue goes away. Another question, is there any option to show scanlines? I haven't found anything so I'm guessing not but thought I would double check. Thanks!
