DSVita vs GB Enhanced+

DSVita is a free Nintendo DS emulator for PlayStation Vita, with an experimental Android port and a documented ARM Linux build. The maker says most games run, although some emulation features are incomplete. Two-dimensional rendering is mostly complete, while three-dimensional rendering is mostly implemented; missing effects and games using 3D on both screens can cause slowdowns or stutters. When ARM7 HLE fails, SoundHle or AccurateLle may be more compatible but slower. Release 0.9.4 lists savestates, Action Replay and libretro cheats, touchscreen controls and customizable control profiles. The rear touchpad can map to the DS touchscreen, and the right stick can control it. ROM files must use the .nds extension and be placed in ux0:data/dsvita. Vita installation requires libshacccg.suprx and kubridge.skprx 0.3.1 or later. Automatic frame skipping is always used, with no scanline rendering. The project recommends overclocking the Vita to 500MHz.

GB Enhanced+ is a free, open-source emulator for DMG, Game Boy Color, Game Boy Advance and Pokémon Mini systems, available on Windows, Linux and macOS. Nintendo DS emulation is described as experimental. The project focuses on emulating peripherals and less common hardware, with support listed for the Wave Scanner, Wantame Card Scanner, Vaus Controller and WorkBoy. It also supports link-cable emulation, real-time clock features, save states and controller input. Configuration options include joystick haptics, accelerometer input for motion controls and netplay settings for linking emulator instances. The emulator can automatically apply an IPS or UPS patch file when it shares a name with a ROM. PDF and ODT manuals cover operation, netplay, rumble support and motion controls. Building it requires SDL 2.0, OpenGL 3.3 or greater, a C++ compiler and CMake; Windows also requires GLEW. Qt for the GUI and SDL2_net for netplay are optional. It is licensed under GPLv2. Save states from version 1.9 and earlier are incompatible with version 1.10.
