BlastEm vs Panda3DS

BlastEm is a free, open-source emulator for Sega's 16-bit and 8-bit consoles. It supports Genesis/Mega Drive, Sega CD, 32X, Master System, Game Gear, SG-1000, SC-3000, Sega Pico, and Yamaha Copera. Downloads are listed for Linux, macOS, and Windows, with an experimental web version. Gameplay features include save states, cartridge save RAM and EEPROM support, turbo and slow modes, controller input, and VGM logging. Its integrated debugger can inspect and modify state, set conditional breakpoints, run scripts, and show visual VDP tools. Developers can use the GDB remote debug protocol for source-level debugging of SGDK and other C or C++ projects. The maker describes it as fast enough for older PCs and accurate enough for demanding demos. Most Sega CD and 32X games are playable, but compatibility is not perfect. Yamaha Copera emulation is incomplete: games generally lack music, though Copera-specific ADPCM samples play. The listed macOS download is x86-64 and not notarized; the page directs ARM users to Homebrew.

Panda3DS is a free, open-source emulator for Nintendo 3DS games on computers and portable devices. It supports Windows, macOS, Linux, and Android, with Lua scripting, cheats, controller input, support for some system apps, and work-in-progress amiibo support. The project offers automatically updated nightly builds and manually updated stable builds released every few weeks. Desktop builds include an SDL frontend without a GUI and an experimental Qt frontend with a user interface. Panda3DS is still in early development: many games boot, while many do not, and graphics, audio, and usability features can be incomplete. Compatibility information may not always be up to date, and not all games have been tested. Android is also early in development, so compatibility and performance may differ from desktop. Audio support is experimental; the configuration menu is still being developed, and settings must be changed by editing config.toml in a text editor. The emulator is licensed under GPLv3.
