Open95Keygen PSX is an open source Playstation 1 homebrew program that generates random valid Product Keys (both OEM and Retail types) for Microsoft’s Windows 95 and Windows NT 4.0 operating systems. It is a port of my Open95Keygen program to the PSX.
The Windows 95/NT 4.0 OEM/Retail Product Key algorithms have been reverse engineered by many people. Open95Keygen is a clean room design implementation not based on any existing software, it is written based on the specifications of the algorithm which is inherently not copyright infringement. I was inspired to write Open95Keygen after watching the YouTuber stack smashing’s video Why 111-1111111 is a valid Windows 95 key.
View all releases.
Burn and boot a CD-R on your PS1 or PS2 console using a method to start backup CD-Rs, or load the standalone .exe by other means.
Make sure a controller is connected, and simply press the cross button. Retail and OEM Product Keys will be displayed. You can press the cross button for even more keys as much as you want.
Next you need to place the file
LICENSEJ.DAT (for building Japan bin+cue) in the same directory as the makefile to license the built images. These files can be obtained from the official PSX PSYQ SDK.
make- just build o95kg.exe.
make jp-cd- build o95kg.exe and create bin+cue files.
make clean- delete any files built with an above rule.
make test- Load your previously created bin+cue files with the PCSX-R emulator.
Open95Keygen and Open95Keygen PSX are released under the 3-BSD license. For more info, see the file
