| Spec | RebitPlay | Delta Emulator | What it means |
|---|---|---|---|
| Best fit | Players who want browser play, account storage, public profiles, sharing, Discover, netplay rooms, and supported systems beyond Nintendo-only libraries. | iPhone, iPad, and Apple ecosystem users who want a polished native Nintendo emulator with skins, local library management, Delta Sync, and Apple controller support. | Delta is excellent for native iOS Nintendo emulation. RebitPlay is broader as a web social library and includes PlayStation support. |
| Install model | Browser app and installable PWA, with Android Play Store distribution configured for mobile install paths. | Native iOS/iPadOS app available through the App Store outside the EU and AltStore PAL in the EU, with beta and Patreon flows documented separately. | Delta feels more native on Apple devices. RebitPlay is easier to open from any modern browser. |
| Supported systems | NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, Nintendo DS, and PlayStation. | NES, SNES, Nintendo 64, Game Boy, Game Boy Color, Game Boy Advance, Nintendo DS, and Sega Genesis according to Delta import docs. | Delta has N64 and Genesis. RebitPlay has PlayStation and a browser-hosted social layer. |
| ROM ownership | Bring your own legally owned ROMs. RebitPlay does not provide copyrighted ROM downloads. | Bring your own ROMs. Delta documentation explains importing ROM files into the local library. | Both products rely on user-provided game files. |
| Library model | Account-backed library with upload, RomM import, system detection, hash lookup, box art, public game pages, sharing, and cloning from public pages. | Native local library with artwork, controller skins, game settings, import flows, and Delta Sync for library data. | RebitPlay emphasizes public web pages and cross-device account storage. Delta emphasizes an elegant local Apple app. |
| Cloud sync | Cloud-save-friendly account storage for ROMs, in-game saves, save states, screenshots, and media. Free includes 2GB; Pro includes 20GB. | Delta Sync can sync games, save files, skins, and BIOS files through Google Drive or Dropbox. | Delta uses your cloud provider. RebitPlay uses its own account storage model. |
| Save states and SRAM | Manual states, autosaves, SRAM uploads/downloads, thumbnails, and storage cleanup inside the game UI. | Save states, locked states, backup states, quick save/load, and synced save data through Delta Sync. | Both are strong. RebitPlay adds account media storage and public game context around saves. |
| Multiplayer | Room-based netplay with lobby/discover, Room IDs, LAN mode, chat, player lists, and GBA Link Cable beta. | Local multiplayer for selected systems and online-compatible Nintendo DS games through community Nintendo WFC servers. | Delta multiplayer is strong inside its supported native model. RebitPlay is more room/lobby oriented. |
| Link cable | GBA Link Cable beta for compatible Game Boy Advance games, with host/join room codes, Player 1/2 roles, and in-game save export. | Delta docs focus on local multiplayer and DS online multiplayer; GBA link cable is not positioned as the same public room-code product flow. | RebitPlay currently has the clearer GBA link-cable path for online room sessions. |
| RetroAchievements | Settings connection, game achievements, recent achievements, public profile context, and automatic screenshots on unlock. | Delta release notes describe RetroAchievements as an experimental feature with NES, SNES, and N64 support at launch, with more systems planned. | RebitPlay treats RetroAchievements as part of the documented account experience. |
| Controls | Touch controls, draggable layouts, d-pad styles, keyboard mapping, gamepad support, and remote phone controller mode. | Native controller skins, opacity settings, haptic feedback, controller mapping, keyboard support, AirPlay, and quick actions. | Delta is highly polished on iOS. RebitPlay is better when your group is split across browsers and devices. |
| Cheats | Import .cht files, add manual cheats, enable/disable cheats, and manage them in the game UI. | CheatBase and cheat management are documented in Delta release notes and public materials. | Both support cheats. Delta has strong native iOS presentation. |
| Social and discovery | Followers, friends activity, top players, trending games, public profile pages, public game pages, sharing, and active room discovery. | Primarily a personal native emulator library, not a web social retro-gaming platform. | This is a major RebitPlay advantage if community and public pages matter. |
| Pricing | Free plan with 2GB storage. Pro plan with 20GB storage, console themes, shader presets, and upcoming Pro perks. | App Store app is free, with Patreon and beta/experimental benefit paths documented by Delta. | Delta is very compelling for free iOS use. RebitPlay charges for hosted storage and convenience. |
The point is not to be every emulator. RebitPlay focuses on account-backed browser play, multiplayer rooms, and a social library.
RebitPlay is not tied to one native ecosystem. It is designed around browser play, installable PWA behavior, account storage, and cross-device continuity.
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.
Netplay rooms, lobby discovery, chat, LAN mode, and GBA Link Cable room codes give groups a clearer route into playing together.
