Retro Papa PS5 Beta

Retro Papa is a native retro frontend for jailbroken PS5s. This repo contains beta builds.

No ROMs, disc images or PlayStation BIOS files are included.

Install

First install or update

1. Run your normal exploit / etaHEN setup.
2. Open PayloadManager.
3. Load RetroPapa-Installer.elf.
4. Wait for the Retro Papa notification.
5. Open Retro Papa from the Games screen.

After a reboot

1. Run your normal exploit / etaHEN setup.
2. Open PayloadManager.
3. Load RetroPapa-Start.elf.
4. Open Retro Papa from Games.

You do not need to load the large installer after every reboot. RetroPapa-Start.elf only starts the resident Retro Papa service.

Tested on PS5

• Nintendo Entertainment System - Mednafen
• Super Nintendo - LakeSnes
• Mega Drive / Genesis - Mednafen
• PlayStation - Mednafen
• Arcade - FBNeo

Not tested yet

Mednafen itself supports more systems, but they are not wired into Retro Papa or tested on PS5 yet:

• Apple II / II+ / IIe
• Atari Lynx
• Neo Geo Pocket / Color
• WonderSwan / WonderSwan Color
• Game Boy / Game Boy Color
• Game Boy Advance
• Virtual Boy
• PC Engine / TurboGrafx-16 / CD
• SuperGrafx
• PC-FX
• Sega Game Gear
• Sega Master System
• Sega Saturn

Do not treat these as supported yet. A system only moves to the tested list after it works through Retro Papa on real PS5 hardware.

The beta package includes the current ROM folders, PS1 BIOS setup, controls and save instructions in README.txt.

Existing data

The installer is meant to leave your own data alone, including ROMs, BIOS files, saves, states, settings and favorites. Keep a backup of anything important before testing beta builds anyway.

Downloads

Beta builds are posted in Releases. Each release includes hashes so you can verify the files you downloaded.
