Rebit highlights
What Rebit does differently
A browser library, cloud saves, and multiplayer rooms around the games you already own.
Web-first across devices
RebitPlay is not tied to one native ecosystem. It is designed around browser play, installable PWA behavior, account storage, and cross-device continuity.
Social library layer
Public profiles, game pages, share links, followers, friends activity, and active rooms make RebitPlay feel closer to a retro-gaming platform than a solo emulator app.
Room-oriented multiplayer
Netplay rooms, lobby discovery, chat, LAN mode, and 2P, 3P, or 4P GBA Link Cable room codes give groups a clearer route into playing together.
Delta Emulator highlights

Excellent iOS-native feel

Strong Nintendo focus
Delta covers major Nintendo handheld and console systems, including N64 and DS workflows that many iOS players specifically want.
Delta Sync flexibility
Using Google Drive or Dropbox can be attractive for people who already trust those providers and want to keep sync outside a new gaming account.
Tradeoffs
Pick what fits how you play.
The right choice depends on your systems, devices, and how much setup you enjoy doing yourself.
Native polish vs browser reach
Delta feels better as a native iOS app. RebitPlay is easier to position as a cross-device browser service with shared web pages.
Nintendo focus vs mixed systems

Third-party sync vs hosted storage
Delta Sync uses Google Drive or Dropbox. RebitPlay uses Rebit account storage, which is simpler in-product but tied to storage limits.
