Short answer: for most players, mGBA is the best Game Boy Advance core in 2026. The gpSP core is the specialist pick for weak hardware. The Libretro project says to use it only when mGBA or VBA-M cannot keep full speed.
Who This Guide Is For
This guide covers the gpSP core for RetroArch, a Game Boy Advance emulator core. It suits retro gamers who want a clear pick instead of a forum argument. Nobody needs another 40-page thread about frame pacing.
Every claim below comes from the Libretro gpSP documentation, the Libretro mGBA documentation, or the Batocera GBA wiki. We ran no private benchmarks. We also invented no speed numbers, because that would be rude to your frame rate.
What Is the gpSP Core?
gpSP is a Game Boy Advance emulator based on notaz's fork of the original. The Libretro docs credit Exophase as the author and list a GPLv2 license.
It began on the PSP and later moved to the OpenPandora, according to the Libretro core info file. That history explains its personality. It runs very fast on low-powered hardware, but it stumbles on some games.
Key facts from the Libretro docs
- Loads .gba and .bin files.
- BIOS file gba_bios.bin is optional.
- Supports saves, save states, rewind, and remapping.
- Reports 59.72750057 FPS and a 3/2 aspect ratio.
- Lists no core options, so there is little to tweak.
gpSP vs mGBA: Side-by-Side Comparison
The table uses only facts from the sources above. Where a source was silent, we left the cell out instead of guessing.
| Feature | gpSP | mGBA |
|---|---|---|
| Systems | Game Boy Advance | GBA, Game Boy, Game Boy Color |
| BIOS file | Optional | Optional |
| Reported sample rate | 65536 Hz | 32768 Hz |
| Core options | None listed | Yes, such as Game Boy model |
| Libretro's advice | Use when other cores run too slowly | Listed as a better option for most users |
| Origin | PSP and OpenPandora emulator | Aims to be faster and more accurate than many GBA emulators |

Sample rate at a glance
A bigger bar looks impressive. It does not make a better core.
Core-reported sample rates from the Libretro docs. This is a spec, not a quality score.
When gpSP Is the Right Choice
Think of gpSP as the little engine that could. It suits a narrow job, and it does that job well.
- Your handheld or old PC stutters on mGBA.
- You tried VBA-M and it also ran below full speed.
- Your games sit outside the known problem list below.
- You want a lightweight fallback core installed.
Not on that list? Start with mGBA. The Batocera wiki says mGBA aims to be faster and more accurate than many existing GBA emulators.
Known gpSP Compatibility Problems
The Libretro docs keep a compatibility list for gpSP. Here is a selection of it.
| Game | Reported issue |
|---|---|
| Banjo-Kazooie: Grunty's Revenge | Black screen during the developer logo |
| Boktai Trilogy | Solar sensor is not emulated |
| Final Fantasy VI | Background and tiling order issues |
| Harry Potter: Quidditch World Cup | Crashes when going in-game |
| WarioWare: Twisted! | Tilt sensor is not emulated |
| Yoshi's Universal Gravitation | Tilt sensor is not emulated |
Source: Libretro gpSP compatibility section.
Sensor games deserve a special warning. The docs list the Boktai solar sensor and tilt sensors as unsupported. No sensor, no sunshine, no fun.
How to Set Up the gpSP Core
Setup takes a few minutes. RetroArch handles most of it, as the Libretro getting started guides explain.
- Install RetroArch on your device.
- Open Load Core and download the gpSP core.
- Optional: place gba_bios.bin in the system folder.
- Check the file's MD5 against a860e8c0b6d573d191e4ec7db1b1e4f6.
- Load your .gba file and choose gpSP.
- Save your battery data. It appears as a .srm file in the save folder.
Use only games you legally own. That keeps your setup clean and your conscience quiet.
How to Choose Your Core in Five Steps
- Start with mGBA on your device.
- Test one demanding game for several minutes.
- If speed drops, try VBA-M next.
- Still slow? Switch to gpSP.
- If a game glitches, check the compatibility table above.
This order follows the Libretro guidance. It saves you from tuning a core that was never the right fit.
Common Mistakes to Avoid
- Picking a core because its sample rate looks bigger.
- Skipping the compatibility list before blaming your device.
- Mixing save states between different emulators. The Libretro blog warned non-Libretro save states may not be compatible.
- Expecting gpSP to emulate tilt or solar sensors.
- Searching for a "perfect" core instead of a good one.
Frequently Asked Questions
Is the gpSP core the best GBA core in RetroArch?
Not for most people. Libretro says mGBA or VBA-M are better options for most users. It points to gpSP only when those cores cannot keep full speed.
Does the gpSP core need a BIOS file?
No. The Libretro docs list gba_bios.bin as optional for gpSP. If you add one, its MD5 should be a860e8c0b6d573d191e4ec7db1b1e4f6.
Which file types does the gpSP core load?
The Libretro docs list .gba and .bin files. Zipped ROMs are not mentioned for this core.
Does gpSP support save states and rewind?
Yes. The Libretro documentation marks saves, states, and rewind as supported.
Can mGBA play Game Boy and Game Boy Color games?
Yes. The Libretro docs say mGBA also supports Game Boy and Game Boy Color games.
Other GBA Cores You Can Try
gpSP is not the only option in RetroArch. The Libretro docs list several Game Boy Advance cores in the same section. Each one links to its own page with settings and known issues.
- mGBA: the all-rounder, and the default core in ROCKNIX.
- VBA-M: the second opinion, named alongside mGBA in Libretro's gpSP advice.
- VBA Next: another VBA-based core in the docs.
- Beetle GBA: listed under the same GBA section.
- Meteor: also listed in that section.
- TempGBA: a separate core that the docs list beside gpSP.
The docs also show cores that cover several systems, such as SkyEmu and MesenCE. They list GBA support in their names. Check their pages before you switch, because a wider feature set can mean a heavier load.
Why the 2026 date matters
Emulator docs change often. The gpSP page we used shows an October 2026 update, and its compatibility list still names the issues above. If you read an old forum post, check it against the current page first.
Frontends also set their own defaults. Batocera says it uses the latest Libretro core for mGBA. That means your device may already pick a sensible core for you.
Final Verdict
The best gpSP core in 2026 is the one you only reach for when needed. Choose mGBA first, test VBA-M second, and keep gpSP as your speed-focused backup. Read the compatibility table before you blame the emulator.
