Avocado vs Plato

Avocado is a free, open-source PlayStation 1 emulator for Windows, macOS, Linux, and Android. It can load files including .cue, .bin, .img, .chd, .ecm, .exe, .psexe, .psf, and .minipsf by drag and drop. Listed save tools include save states, quick save and load, and rewinding by one second. It supports digital controllers, DualShock, and mouse input, with up to two controllers and no multitap. Audio support includes XA-ADPCM and Red Book, and graphics use OpenGL hardware rendering. The project lists support for Anti-Modchip and LibCrypt protected games; PAL LibCrypt games need additional .SBI or .LSD subchannel information. A BIOS from a real console is required and must be placed in the data/bios directory; BIOS selection is prompted on first run. The project is in early development, so games may not start or may crash soon after. It is single-threaded, and audio synchronized to NTSC 60 Hz can stutter in PAL games.

Plato is a Linux command-line platform for topology optimization, helping designers develop geometry that meets functional requirements. It solves topology and shape design problems with adjoint methods for gradient-based optimization. Documented objectives include increasing stiffness or heat flow and reducing stress. Plato coordinates workflows involving geometry, meshing, and physics simulation packages. It includes the open-source physics code Plato Analyze and can also be used with a growing set of internal Sandia physics codes. Research features described for the platform include structural optimization across multiple materials, uncertainty-aware structural optimization, level-set methods, and a massively parallel kernel filter. A graphical interface is in development for selected applications. The open-source version is listed at free, with a limited set of objectives and constraints. A license is required to obtain an installation package.
