Pros & Cons
Pros
Utilizes CPU recompilers for x86-64, ARM, and RISC-V architectures, delivering high-speed emulation on everything from low-end devices to modern systems, as highlighted in the hardware support section.
Offers hardware-accelerated upscaling, PGXP geometry correction, and post-processing shader chains to modernize PS1 graphics without sacrificing accuracy, detailed in the features list.
Includes save states with rewind and runahead, RetroAchievements integration, and per-game configuration for a tailored retro gaming experience, as specified in the advanced features.
Supports digital/analog controllers, lightguns via mouse, NeGcon, and multitap, with extensive binding options and automatic mapping, making it versatile for various setups.
Cons
The Android app explicitly states no support is provided, and users are discouraged from seeking help, making it unreliable and frustrating for mobile emulation enthusiasts.
Requires users to dump their own PS1/PS2 BIOS ROM, which can be confusing and legally ambiguous, creating a barrier to entry for non-technical users.
Only supports Windows 10/11 and newer, with no assistance for older versions, forcing upgrades or reliance on outdated, unsupported builds.
