| BIOS requirement | Avocado requires a BIOS from a real console, placed in the data/bios directory, and prompts for BIOS selection on first run. | A PS1 or PS2 BIOS ROM image is required, and the emulator does not include one; the maker says users should dump it from their own console. |
| License | The repository identifies its license as GPL-2.0. | The project states it is licensed under GNU GPLv3 or later, while noting that it is effectively GPLv3 only for now. |
| Product | Avocado describes itself as a modern PlayStation 1 emulator. | QuackStation is a PlayStation 1 emulator with a Qt front end and a fullscreen/TV interface based on Dear ImGui. |
| Support | The maintainer directs users to the GitHub issue tracker, Twitter, and a Discord server for questions and bug reports. | The README says packages from sources other than GitHub Releases may be out of date and are not supported by the developer. |
| System requirements | The README specifies Windows 7 or later, macOS 10.13 or later, or Linux Ubuntu 16.04 or later, plus an OpenGL 3.1 GPU and an SSE3-compatible x86 or x64 processor. | The listed CPU architectures are x86_64 with SSE4.1, ARMv7, ARM64, or RISC-V/RV64; hardware rendering requires a GPU supporting OpenGL 3.1, OpenGL ES 3.1, Direct3D 11 Feature Level 10.0, or Vulkan 1.0. |

In their own words
Avocado
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.
QuackStation
QuackStation is a free PlayStation 1 emulator with a Qt front end and a fullscreen interface for TV use. Its project goals include playability, speed, long-term maintainability, and performance suitable for low-end devices. It supports hardware rendering through D3D11, D3D12, OpenGL, Vulkan, and Metal, as well as software rendering. Hardware graphics options include upscaling, texture filtering, 24-bit true colour, and PGXP geometry precision and texture correction. Playback features include save states, runahead, rewind, fast boot, CPU overclocking, and time-stretched audio. Games can load from CDs and formats including BIN/CUE, raw BIN/IMG, MAME CHD, ECM, MDS/MDF, and unencrypted PBP. It supports digital and analog controllers, lightguns simulated with a mouse, NeGcon, and multitap for up to eight devices. A PS1 or PS2 BIOS ROM image is required and is not included; users must dump it from their own console. The project is licensed under GNU GPLv3 or later. Android is currently unmaintained and unsupported.
