This Pull Request implements the first take ever on real Soft-Float support in PCSX2. This work is a combination or several efforts and researches done prior. Credits: - https://www.gregorygaines.com/blog/emulating-ps2-floating-point-nums-ieee-754-diffs-part-1/ - https://github.com/GitHubProUser67/MultiServer3/blob/main/BackendServices/CastleLibrary/EmotionEngine.Emulator/Ps2Float.cs - https://github.com/Goatman13/pcsx2/tree/accurate_int_add_sub - PCSX2 Team for their help and support in this massive journey. This pull request should be tested with every games requiring a clamping/rounding mode (cf: GameDatabase). Currently, this PR fixes on the interpreters: - https://github.com/PCSX2/pcsx2/issues/354 - https://github.com/PCSX2/pcsx2/issues/11507 - https://github.com/PCSX2/pcsx2/issues/10519 - https://github.com/PCSX2/pcsx2/issues/8068 - https://github.com/PCSX2/pcsx2/issues/7642 - https://github.com/PCSX2/pcsx2/issues/5257 This is important to note, that this implementation, while technically fixing Gran Turismo 4 and Klonoa 2, makes the games crash due to very high floats being passed in the emu code, and failing at some points later in the process. This has not yet been ironed-out. Other than that, this sets the floor for Soft-Float in PCSX2, a long awaited contribution. |

PCSX2
PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits.
Project Details
PCSX2 has been in development for more than 20 years. Past versions could only run a few public domain game demos, but newer versions can run most games at full speed, including popular titles such as Final Fantasy X and Devil May Cry 3. Visit the PCSX2 compatibility list to check the latest compatibility status of games (with more than 2500 titles tested).
Installers and binaries for both stable and nightly builds are available from our website.
System Requirements
PCSX2 supports Windows, Linux, and Mac platforms. Our setup documentation page contains additional details on software and hardware requirements.
Please note that a BIOS dump from a legitimately-owned PS2 console is required to use the emulator. For more information, visit this page.
Contributing / Building
PCSX2 supports translation into other languages using Crowdin.
