M2EA
v0.5.1 Android 7.0+A Sega Model 2 arcade emulator optimized for Android.
If you find this project valuable, consider supporting via Ko-fi:
What's new in 0.5.1
0.5.1 rolls up the 0.5.0 engine overhaul plus the launcher and audio fixes found during testing. Save states and EEPROM/backup RAM from 0.4.x still load.
- i960 ARM64 JIT rewritten. Multi-word load/store bursts compile to native ARM64 with fastmem helpers, every non-control-flow instruction runs in-block, and interpreter fallbacks drop to zero.
- Dual-core pipeline. Emulation and GLES rendering run on separate performance cores, with exactly one emulated frame per rendered frame at 57.5 Hz.
- Model 2B (SHARC) speedups. Fixes the character-intro stutter in Fighting Vipers and Last Bronx.
- Incremental uploads. 3D palette rows and 2D HUD spans only upload what changed instead of re-sending up to 1 MB per frame.
- Benchmark mode. Attract-only, factory-fresh board, uncapped swap chain, CPU-clock split on the result card.
- Raw arcade TEST menu shortcut. The gear pill on a selected cover boots the board straight into its native TEST menu, with COIN mapped to SERVICE and START mapped to TEST.
- Launcher. A clearer empty-library screen, FIND lists the ROM zip files with multi-select delete, and IMPORT GAME COVERS (.zip) fills the cards immediately.
- Audio. VF2's reverb return is rebalanced and Bluetooth output no longer drops samples.
- Manx TT Superbike Revision C (manxttc) is now supported, with the Twin sound ROMs and its own EEPROM seed.
Audio in 0.5.1
Virtua Fighter 2 / VF2O. The arcade board's SCSP reverb return is unusually hot in this game, so at the default setting it buried the sound effects under the music. The wet return is now scaled to 10% of the SCSP REVERB slider (5% at the default position, the 25% position of the first beta), and VF2/VF2O use the standard 5.6 board gain again, so their overall level matches the other SCSP titles.
Bluetooth. Deep-buffer sinks such as A2DP, SCO and BLE headsets never reach Android's fast mixer, and a 25 ms queue was too shallow: the sink emptied it every few seconds and the stream was cut, which is heard as a pop or crackle. The output now classifies the sink from getDevices() and gives deep-buffer devices 1024-frame buffers, a 64 ms target and an underrun-triggered adaptive boost. Wired and speaker output keep the original 480-frame, 25 ms low-latency path.

Installing games
- Use MAME rom-sets. Do not unzip the archives or rename them.
- Copy the
.zipfiles to your device, and use FIND → ADD FOLDER or IMPORT ZIP FILES in the UI Panel. - NVRAM seeds are bundled per set. Settings changed in the native TEST menu are saved to
files/nvram/SET/, where SET is the ROM set name. - Save states live next to the NVRAM data and survive updates.
Cover art
The emulator reads images from files/covers/. Use FIND → IMPORT GAME COVERS (.zip), which flattens folders and maps full titles such as Last Bronx.webp/.png onto the set name. Cards reload as soon as the pack is installed. Or you could name each file after the ROM set (fvipers.png, lastbrnx.jpg, …) and load images into files/covers/ by yourself.
Legal. M2EA ships no games, BIOS files or Sega artwork and provides no ROM downloads. Use only ROMs you legally own.
