Avocado vs OpenLSTO

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.

OpenLSTO is open-source C++ software for structural topology optimization using a level set method. It seeks to minimize compliance, or maximize stiffness, within a volume constraint in a two-dimensional design domain. Developed and maintained by researchers at UC San Diego and Cardiff University, the described first light version is limited to that 2D problem. It runs through command-line arguments in a terminal; simple serial cases without external libraries can be compiled and executed with a C++ compiler. OpenLSTO produces.vtk solution files that ParaView can read, so users need a data visualization tool for post-processing. The project favors in-house components where possible and is available under the Apache 2.0 license. It runs on Linux, macOS, and Windows, with repository-clone and ZIP download options. The software is free: the OpenLSTO plan is free. The project says expanded capabilities using externally provided software are planned for a more advanced version.
