Red Viper v1.1.1 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:
Fixed Virtual League Baseball 2's title screen advancing immediately
Fixed a regression in v1.1.0 which caused enemies to disappear in Red Alarm and scoring in Space Invaders to break (#94)
Fixed keyboard showing up when selecting the red monochrome tint
Improve graphical oddities when exiting pause menu in Golf
Improve occasional glitches during Jack Bros. level transitions
Improved performance regressions introduced in v1.1.0
Fixed softlock when loading abarth's wireframe demo
Fixed ROM loader crash in folders with only one ROM (#90)
Disable antiflicker when software rendering is active - in this case, there is likely no flickering to protect against, and it was causing issues
