Red Viper v1.0.1 is released. A Virtual Boy emulator for the Nintendo 3DS continuing mrdanielps's work on r3Ddragon, which is itself based on Reality Boy / Red Dragon. It uses a dynamic recompiler with busywait detection and a hardware-accelerated renderer to achieve high performance on the 3DS's limited hardware.

Red Viper Changelog:
This patch improves the UX for multicolor mode, allowing people to more easily share their palettes with others, and fixes some bugs that snuck into the v1.0.0 release.
Multicolor changes:
Up to 4 palette slots are available, configurable per game
Color entries and brightness scale can now entered directly using hex color values
These same raw color and brightness values are visible within the emulator
Boost maximum brightness scaling factor from 2x to 4x
Fix random crashes during screen transitions in Golf
Fix bug where toggling anaglyph mode while in-game caused games to speed up
Ensure Circle Pad Pro applet runs at 60Hz
