PlayStation 3

Requirements:

• PlayStation 3 with access to dev_flash.

There are many ways of doing this, so the process will be summed up (for now?):
Copy /dev_flash/ps1emu/ps1_rom.bin to User Directory/bios.

PlayStation Portable (PSP)

Requirements:

• PlayStation Portable with custom firmware.
• PRX Decrypter
• PC with hex editor such asHxD

1. In the XMB, press Select to bring up the VSH Menu. Under 'USB device' select 'Flash 0'. Connect the PSP to your PC.
2. From the folder kd copy the file pops_xxg.prx to your PC. (The file can be named pops_01g.prx to pops_11g.prx. It depends on your PSP model.) The file is around 463 KB. Disconnect the PSP.
3. Use the VSH Menu to set 'USB device' back to 'Memory Stick'.
4. Extract PRX Decrypter to the root of the Memory Stick. Create a folder enc in the root of the Memory Stick and copy pops_xxg.prx inside it. Disconnect the PSP.
5. Launch PRX Decrypter and select 'Decrypt/decompress files', press X to confirm. Once finished, return to the XMB and connect the PSP to your computer. The file pops_xxg.prx inside the enc folder should be around 1114 KB now.
6. Use HxD to cut out the PS1 BIOS from inside pops_xxg.prx. The BIOS file begins at hex offset 54E08 and is hex 80000 bytes (512 KB) long. If done correctly, the extracted code should have Sony Computer Entertainment Inc at offset hex 108 and System ROM Version 4.5 at offset hex 7FF32.

Note that pops_xxg.prx is marked as a system file, and may be hidden in your file manager by default. This information was adapted from this post.
