FS-UAE vs UAE4ARM

FS-UAE is a free Amiga emulator for Linux, macOS, and Windows, with an emphasis on games and support for high-end Amiga systems. It emulates systems including the Amiga 500, 500+, 600, 1000, 1200, 4000, CD32, and CDTV. It accepts floppy images such as ADF and IPF, CD-ROM images such as ISO and BIN/CUE, and computer folders mounted as Amiga hard drives. Its optional graphical Launcher configures the emulator without configuration files and can identify games through the Open Amiga Game Database, retrieving covers and screenshots. The Launcher can also recognize many archived WHDLoad games. An on-screen menu supports gamepad control for tasks such as changing disks and loading save states. FS-UAE supports cross-platform online play and offers graphics options including aspect correction, zoom, shaders, and visual themes. It is free software under GPLv2, with some project parts and dependencies under other open-source licenses. It requires a moderately fast computer with accelerated OpenGL graphics; a gamepad or joystick is recommended, and users should ideally have the Kickstart ROMs for the systems they want to emulate.

UAE4ARM is a free Android port of an Amiga emulator. It supports AGA, OCS, and ECS Amiga models and reads ADF, ADZ, HDF, ISO, CUE, and RP9 disk images. Kickstart is not included. Audio support uses WinUAE’s paravirtual AHI driver for 16-bit sound through AHI. Graphics include RTG modes sized to the device screen and an option to preserve the 4:3 ratio. Input can use touch, on-screen controls, a Bluetooth mouse, or selectable joystick and cursor-key D-pad modes. File dialogs browse internal storage, SD cards, and readable USB volumes, including removable media connected through an OTG adapter. Save-state files and preview images stay together, and users can choose the save-state folder. Release notes identify version 1.0.5.5 as the latest release and add 16-bit AHI sound support. They also state that 32-bit Android devices are supported with JIT disabled; enabling JIT can freeze the emulator when returning to emulation. The project is GPL-2.0 licensed, free of charge, and provided without warranty.
