MemcardRex Alternatives: Best PS1 Save Tools Compared
MemcardRex is the most complete free PS1 memory card editor, but it is not the only tool, and since its repository was archived some people are looking around. This comparison covers the realistic alternatives, what each does well, where each falls short, and which one fits emulator players, console owners and collectors.

What to compare
Formats and hardware
The biggest difference between tools is how many card formats they open and whether they can read physical cards. Those two points decide most choices.
Platform and maintenance
Check which systems each tool runs on and whether it is still maintained. An unmaintained tool can still work well, but there will be no fixes. This matters more for tools that talk to hardware or depend on a runtime, because operating system updates can break them. File-only tools tend to age better.
MemcardRex
Strengths
16 card formats, 7 single-save formats, five hardware interfaces, PSP and PS3 virtual cards, undo history and plugins. It is free under GPL-3.0. It also opens cards in tabs side by side, which makes merging saves from different emulators quicker than in single-window tools.
Weaknesses
The project was archived in July 2026, it needs .NET 8, and Linux support is a beta you build yourself. In practice the archive status matters less than it sounds: the existing builds keep working, and PS1 card formats will not change. Keeping a copy of the release you use covers most of the risk.
DuckStation's memory card editor
Strengths
DuckStation includes its own memory card editor, so its users can copy and delete saves without installing anything else. For people who only play through DuckStation, that convenience is hard to beat, and there is no format conversion to worry about.
Weaknesses
It is designed around DuckStation's own cards rather than the full range of formats and readers. DuckStation's licence is now source-available rather than open source.
PSXGameEdit and older tools
Where they fit
PSXGameEdit is a classic Windows editor many long-time users remember, and MemcardRex still opens its .mc and .mcs formats.
Why most people move on
It is no longer maintained and lacks modern formats such as .VMP, .VM1 and .srm.
Apollo Save Tool
On-console management
Apollo runs as homebrew on PSP and PS3 and manages saves directly on the console, including PS1 virtual card saves.
Trade-offs
It requires homebrew, and it does not replace a PC editor for emulator cards or physical card readers. Many people use both: Apollo on the console for quick jobs, and MemcardRex on a PC for conversions and backups.
Which should you choose?
Recommendations
Use MemcardRex for anything involving several formats or real cards. Use DuckStation's editor for quick jobs inside DuckStation. Use Apollo when you want to stay on the console. See the full comparison table.
Keep your options open
Whatever you choose, keep backups of your card files in a raw format such as .mcr, which every tool and emulator can read.
Frequently asked questions
Is there a newer replacement for MemcardRex?
No direct successor has been announced. MemcardRex releases still work, and its formats are stable, so it remains a good choice.
Which alternative supports the most formats?
None of the common alternatives matches MemcardRex for card formats and hardware readers combined.
Can I use more than one tool?
Yes. Card files are interchangeable once converted, so you can mix tools, as long as you keep backups.
