Red Viper v1.1.0 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 release improves the software renderer and enables it for Test Chamber on New 3DS. This fixes the issue where black walls may appear transparent.
The old 3DS is not fast enough to run a software renderer, so it is not enabled there. There is an alternative solution that could work on the o3DS, but it is not yet clear whether this solution is viable. See #88 for more information.
Improve software renderer and enabled it for Test Chamber on New 3DS, fixing see-through black walls
Fixed XB instruction not saving when register is in-memory, resulting in crashes in the comet shooting minigame in Galactic Pinball's Colony stage (#87)
Numerous improvements to interpreter
These changes do not affect any existing games, but do make it easier to test the emulator in alternate environments
