An open source NES emulator written in java mainly as an educational project.

version 0.0.7 has been released. It switches over to a spring based design, implements MMC1 and Unrom mapper, corrects an issue with vertical scrolling, and is slightly faster than 0.0.6.

version 0.0.8 is in the process of being prepared for release. It corrects some sprite transparency issues that were in the previous versions, and runs at correct speed. 8x16 sprites are implemented in this version, but rendering appears to have some issues. MMC1 prg-ram is implemented in 0.0.8 and appears to work pretty ok.

features:

working ppu

visualizations of palettes and pattern tables.

unimplemented:

apu, several dozen mappers, 8x16 sprites.
