The PSxMemCard, based on the SD2PSX open-source project, is a high-performance memory card replacement for PlayStation 1 and PlayStation 2 consoles. Unlike traditional memory cards with limited storage, this device supports microSD cards up to 512GB, allowing you to store thousands of game saves across multiple virtual memory cards. Compatible with both PS1 and PS2, it emulates original memory card sizes (128KB for PS1 and customizable 1MB–64MB for PS2), ensuring seamless game save management. The plug-and-play design makes it easy to use, while the front-facing USB-C port allows for firmware updates, keeping it compatible with new software enhancements. The PSxMemCard also supports FreePSXBoot and FreeMCBoot, providing soft modding capabilities for added flexibility. Additionally, the ability to store and play PS1 and PS2 games directly from the microSD card reduces load times and enhances the gaming experience. Designed with open-source and community-driven improvements, this memory card ensures long-term support and continued innovation. Whether you're preserving your game progress or looking for a modern storage solution, the PSxMemCard is an essential upgrade for any retro gaming enthusiast.
