Red Viper v0.9.2.1 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 v0.9.2.1 Changelog:
This patch features fixes for a few critical bugs that snuck into v0.9.2, including the .cia not working on O3DS and the crash screen causing a ghost image when left alone for too long.
