Nintaco (2018/06/30) Beta is released. Nintaco is a work in progress. It is a NES-Famicom-Dendy emulator written in Java 8, ostensibly making it cross-platform. The full source will be made available per LGPLv2.1.

Getting Started
If double-clicking the jar does not automatically launch the emulator, try: java -jar Nintaco.jar
Configure input: Options | Button Mapping...
If you are using an 8 button controller, such as a USB NES gamepad, try mapping Rewind Time to Start + B.
If you want to resume at arbitrary points in the past: Tools | Watch History... and Resume Here

Nintaco (2018/06/30) Beta changelog
Fixed low frame rate issue that occurred on some environments by applying a workaround to a Java bug that inhibits the use of the high-resolution timer during thread sleeps.
Fixed vanishing menu bar problem that happened when the user pressed Esc an even number of times while attempting to exit fullscreen mode.
Fixed image size bug that arose when the user resized the window in between changing video filters of different scales.
