+description = "This is the fastest PC Engine emulator forked from the Mednafen codebase, and it includes an optimized renderer for the PSP's hardware. This speed comes at a cost, though, and a few games don't work with this core. For this reason, if a device can run the non-Fast core at full speed, that one is propably a better choice. Additionally, this core differs from the Beetle-SuperGrafx core only insofar as it does not support SuperGrafx games, so again, unless you need to use this core for a specific reason, you may as well get the added compatibility of the other PCE-compatible cores."

These renderers provide increased internal resolution for smooth, high-res polygons with minimal performance impact, texture filtering and other cosmetic changes. Both varieties of Beetle-PSX are more accurate than PCSX-ReARMed but also significantly slower, so they are generally a better choice for higher-specced devices that can benefit from the additional features and accuracy while maintaining full speed. The Beetle-PSX cores are also very particular about requiring BIOS images, so make sure you have the correct BIOS files available and make sure they are named exactly as the core expects."

The software renderer is more accurate than the OpenGL and Vulkan renderers used in the -HW core, but it lacks some of the cosmetic options and performs any internal resolution increases on the CPU instead of the GPU, which is very demanding (devices with fast CPUs may reach 2x scale but nothing can maintain full speed at 4x at the time of this writing).
