Red Viper v1.2.4 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:
Fixed a bug where toggling anaglyph mode in-game causes a crash with the top screen slowly fading to black
Avoid recalculating column table every frame
