It assumes you want a detailed, actionable publication suitable for an informed audience interested in retro gaming on RetroArch.

Preservation & Backup Practices

• Keep backups of legally owned ROMs and BIOS files in secure storage.
• Catalog ROM versions and checksums for reproducibility (store DAT files and checksums).
• When updating cores, test a sample of games first; document which ROMset versions are compatible.

Part 7: Mobile and Low-Power Devices

If you are running RetroArch on an Android phone, Raspberry Pi 3/4, or Retroid Pocket, the above method works, but you must tweak the core. neo geo roms for retroarch

• Avoid the standard FBNeo core on Raspberry Pi 3 – it struggles with some Neo Geo games (especially Metal Slug 2 due to slowdown emulation).
• Use the “MAME 2003-Plus” core instead.
  • This requires a different ROM set (MAME 0.78 ROMs).
  • Search for “MAME 0.78 Neogeo ROM set.”
  • The BIOS still goes in the system folder.

For iOS (RetroArch via AltStore), FBNeo works perfectly, but you must load the BIOS via the Files app into the RetroArch system directory. Neo Geo ROMs for RetroArch — Comprehensive Guide

• Split/Merged sets save hard drive space by storing shared files in the Parent ROM and linking them to Clones. RetroArch handles this poorly.
• Non-Merged ROMs contain every single file required to run that specific version inside its own .zip file.

Part 7: Performance Tuning & Shaders

Once your ROMs load, you need them to look good on a 4K monitor. The Neo Geo native resolution is 320x224 at a weird refresh rate (59.18 Hz).
