VirtuaNES for 3DS v1.02 is released. This is a port of VirtuaNES to 3DS as an alternative to existing NES emulators. It used to be considered one of the best emulators before FCE and Nestopia, and it runs quite fast for lower spec-ed computers (at the cost of some emulation accuracy). But because of that, the Old 3DS / 2DS is able to benefit from this fast running emulator core. This runs full speed on an old 3DS / 2DS with support for tonnes of mappers. Although it doesn't support every single mapper, the library of games that can run on this are probably fairly huge already.

VirtuaNES for 3DS Changelog:
- Fixed bug in MMC5 mapper that was causing Castlevania 3's graphics to corrupt.
- Optimized rendering to 16-bit buffer to reduce cache misses, and minor optimizations for MMC5 rendering.
- Fixed occassional crashing bug when loading a ROM.
