GBA emulation has been essentially solved for years. The hardware is simple enough that modern phones can run it at full speed without breaking a sweat, and the accuracy gap between emulators has narrowed to the point where most players will never notice a difference. The choice now comes down to platform, features, and how much you care about edge-case compatibility.

Here's what's actually worth using in 2026.

Quick Comparison

1. mGBA — Best Overall (PC / Mac / Linux)

Platform: Windows, macOS, Linux (also available as a RetroArch core and on Switch, 3DS, Wii)
Developer: endrift | Latest release: 0.10.x

mGBA is the gold standard for GBA emulation. It's accurate enough to pass test ROMs that older emulators fail, handles edge cases in save types correctly, and has been the recommended emulator for competitive Pokémon speedrunning and ROM hack play for years.

What sets it apart:

• Cycle-accurate emulation — passes the vast majority of hardware test suites. Games that glitch on other emulators run correctly here.
• Save state support — multiple slots, loadable mid-game
• Shader support — CRT, LCD grid, and pixel-art filters built in
• ROM hack compatibility — handles Flash 1M saves, EEPROM, and SRAM correctly without manual configuration in most cases
• Built-in cheat support — GameShark, Action Replay, and CodeBreaker formats
• No configuration required — drop a ROM in and it runs

For ROM hacks specifically: mGBA handles the unusual save types used by popular hacks (Pokémon Unbound, Radical Red, etc.) correctly out of the box. If you're playing a ROM hack on a repro cart and want to test your patched ROM before flashing, mGBA is the tool to use.

2. RetroArch with mGBA Core — Best for Multi-System Setup

Platform: Windows, macOS, Linux, Android, iOS, consoles
Core: mGBA (or VBA-M for legacy compatibility)

If you already use RetroArch for other systems, adding the mGBA core gives you the same accuracy as standalone mGBA plus RetroArch's unified frontend — achievements via RetroAchievements, netplay, run-ahead latency reduction, and a consistent interface across all your emulators.

When to use RetroArch over standalone mGBA:

• You want RetroAchievements support for GBA games
• You want run-ahead (reduces input latency by 1–2 frames)
• You're building a unified game library across systems
• You're setting up a living room emulation box (Raspberry Pi, Batocera, etc.)

When to use standalone mGBA instead:

• You just want to play GBA games on a desktop without setup overhead
• You're testing patched ROMs

3. Delta — Best for iOS

Platform: iOS 14+
Developer: Riley Testut | Available: AltStore, direct install

Delta is the best GBA emulator on iOS by a considerable margin. It supports GBA, GBC, GB, NES, SNES, N64, and DS in a single app, with a polished interface that feels like it belongs on the platform.

What sets it apart:

• Native iOS design — proper landscape controls, customizable button skins, haptic feedback
• iCloud sync — saves and save states sync across devices automatically
• Controller support — MFi controllers, Xbox, PlayStation all work
• AirPlay support — mirror to Apple TV
• ROM hack support — handles standard save types correctly; for hacks that use Flash 1M saves, apply an SRAM patch first using our patcher tool before loading into Delta

Installation: Delta is available through AltStore (free, requires a computer to install) or directly if your device is enrolled in AltStore PAL. In 2024 the EU App Store changes made third-party distribution easier, and Delta has been available more broadly since then.

4. MyBoy! — Best for Android

Platform: Android 4.0+
Developer: Fast Emulator | Available: Google Play (free and paid versions)

MyBoy! has been the go-to Android GBA emulator for over a decade and still earns its place. The free version covers most use cases; the paid version adds link cable emulation, which matters if you want to trade Pokémon between two instances.

What sets it apart:

• BIOS emulation built in — no need to source a GBA BIOS file
• Fast-forward — up to 16x speed, useful for grinding
• Cheat support — GameShark, Action Replay, CodeBreaker
• Link cable emulation (paid) — trade and battle Pokémon locally on one device or over Bluetooth
• Save state slots — 10 slots per game
• Hardware controller support — most Bluetooth controllers work out of the box

For ROM hacks: Most popular hacks run without issues. Apply an SRAM patch using our tool if you plan to eventually transfer the save to real hardware.

Alternative: RetroArch on Android with the mGBA core is technically more accurate and free, but requires more setup. For a plug-and-play experience, MyBoy! is more practical.

5. VisualBoyAdvance-M — Legacy Option

Platform: Windows, macOS, Linux

VBA-M is the emulator most GBA players used through the 2000s and 2010s. It's still functional and widely compatible, but mGBA has surpassed it on every meaningful metric. The main reason to use VBA-M today is compatibility with old save states you might have from years ago — it can load them, mGBA cannot.

For new setups, use mGBA instead.

Which Emulator Should You Use?

• PC: mGBA, no contest
• iOS: Delta
• Android: MyBoy! (or RetroArch if you want the mGBA core's accuracy)
• Multi-system living room setup: RetroArch with mGBA core
• Just want to test a patched ROM quickly: Any of the above — mGBA is fastest to get started

Playing ROM Hacks on Emulator

All of the emulators above will run ROM hacks without modification for regular gameplay. However, if you plan to:

• Transfer a save to real hardware later — apply an SRAM patch first using our patcher tool so the save format matches what your repro cart or flash cart expects
• Avoid save corruption on certain hacks — some hacks have specific save type requirements; patching before play is good practice

The patcher runs entirely in your browser — drop in your ROM, apply the SRAM patch, and you're done.

Frequently Asked Questions

Do I need a GBA BIOS file?
mGBA and most modern emulators include built-in BIOS emulation that works for nearly all games. A real BIOS dump improves accuracy slightly and is required for a handful of edge cases, but you won't miss it for 99% of the library.

Can I use saves from emulator on a real cartridge?
Yes, with the right tools. GBxCart RW can write save files to real cartridges. The save format must match — if you used an SRAM patch on the ROM, the save will be in the correct SRAM format for most repro carts.

Is emulation legal?
Emulators are legal software. ROMs are a separate question that depends on your jurisdiction and whether you own the original game.
