HalfNES v0.019 is released. HalfNES is an open-source emulator for the Nintendo Entertainment System, written in Java. Currently, it only runs as a standalone Java SE application.

Current Features:
- Supports Mapper 0,1,2,3 games
- SRAM saving works now
- Accurate sound core
- Cross-platform portable

HalfNES v0.019 Changelog:

Fixed the worst of the scrolling bugs. Contra, Castlevania 2, Blaster Master, and many other games are now actually playable. Also, it seems that Yo Noid! crashed the emulator (because bitwise and is NOT the same thing as modulus when you don't have a power of 2!) so I very reluctantly fixed that as well. Known Issues: -Jump sound doesn't cut off in world 1-2 of SMB -Zelda II won't scroll correctly until real sprite 0 hit is implemented -Most games with a status bar on the bottom won't display that bar -Sprites missing in Tiny Toon Adventures, Little Nemo -DuckTales status bar uses wrong graphics -Mario's eyes are missing in SMB2 -Basically every racing game uses the same scrolling trick that won't look right -SMB3 and Marble Madness both crash and Silver Surfer resets itself
