ShendoXT

ShendoXT is a small, enthusiast-driven publisher whose single public utility, MemcardRex, has quietly become the reference tool for anyone who still tinker with original PlayStation 1 save data. Built in C# and wrapped in a no-frills Windows interface, the program opens, inspects and rewrites the 128 kB card images used by the 1994 console, letting hobbyists import/export individual save blocks, repair corrupted slots, convert between Dex-Drive, Bleem!, ePSXe, pSX, Mednafen and real-hardware formats, and even print out cover labels for physical memory cards. Retro-gaming archivists rely on it to migrate decades-old progress from aging cards to modern emulators or flash cartridges, while speed-runners use its checksum restoration to recover accidentally deleted best times. The editor also supports virtual memory cards created by contemporary FPGA-based optical drive emulators, making it useful for both USB-GDROM setups and Raspberry Pi-based replacement boards. Because every byte is mapped to a visual slot grid with color-coded icons, casual users can drag-and-drop saves without touching hex offsets, yet advanced operators still get raw sector views, ASCII note panes and batch verification scripts. ShendoXT’s entire catalog—currently the single MemcardRex executable—can be downloaded free of charge on get.nero.com, where the package is pulled straight from the project’s GitHub release stream via winget, always installs the newest build, and can be queued alongside any other application for unattended batch setup.
