Three reasons:
emuCR_psxmame_20090417.7z is not a tool for playing games today. It is a museum artifact. If you find it on an old CD-R or a forgotten forum link, treat it like a vintage vinyl record—handle it carefully, respect the history, but don't expect it to outperform Spotify.
Should you download it? Only if you are an emulation historian looking to compile a timeline of PS1 emulation. For actual gaming, use DuckStation or modern MAME.
Should you delete it? No. Upload it to the Internet Archive. Every forgotten patch binary is a brick in the road we walked to get to perfect emulation today.

Before we load the BIOS, let’s break down the filename:
To understand this build, you first have to understand the landscape of emulation in the late 2000s. MAME was—and still is—the premier project for preserving arcade games. However, the main MAME branch focuses on a massive breadth of hardware, which sometimes means specific optimizations for individual systems take a backseat to overall accuracy.
PSXMAME was a specialized branch of the MAME source code. As the name suggests, it was tailored specifically to emulate hardware based on the Sony PlayStation architecture. Many arcade systems in the late 90s and early 2000s (such as the Namco System 11 and System 12, and the Sony ZN-1 and ZN-2 boards) utilized PlayStation-based technology.

By stripping away the code for thousands of unrelated arcade machines, PSXMAME aimed to provide a leaner, more focused experience for fans of PS1-based arcade games.
| Component | Meaning |
|-----------|---------|
| emucr | EmuCR – a now-defunct/archived site that provided automated or user-compiled emulator builds, often with unofficial patches. |
| psxmame | A specific MAME derivative/mod focused on Sony PlayStation (PSX) emulation. Official MAME did not prioritize PSX at that time. |

To understand why psxmame existed, you have to understand the emulation war of the 2000s.
The Plugin Problem: Emulators like ePSXe and PCSX relied on separate video, audio, and input plugins. While this offered flexibility, it hurt accuracy. Many games crashed unless you found the "magic combo" of Pete’s GPU and Eternal SPU.
The MAME Philosophy: MAME doesn't care if a game runs slowly. It cares if it runs correctly. MAME emulates the chips—the R3000A CPU, the GTE (Geometry Transformation Engine), the MDEC—clock cycle by clock cycle.
The Birth of PSX MAME: Developers realized that the PSX CPU (MIPS R3000A) was well-documented in MAME’s arcade drivers. By grafting the PSX’s memory map and GPU (the infamous "GPU" chip) onto MAME’s framework, they could theoretically achieve 100% accuracy. psxmame was that experiment.
