SF2000-UAE vs UAE4ARM

SF2000-UAE is free GPL-2.0 software that emulates an Amiga 500 with an OCS chipset and 68000 CPU on Data Frog SF2000 and GB300 handhelds running multicore firmware. Based on uae4all-psp, it uses ADF disk images and is distributed through GitHub Releases with separate handheld builds. Installation requires placing the emulator core, a Kickstart ROM, and ADF game files in specified SD-card folders; Kickstart is not included. The README recommends Kickstart 1.3, and release notes state that versions 1.3 and 2.0 work while 3.0 does not. AGA games cannot run because the emulator targets OCS. Controls map the D-pad to joystick directions, A and B to fire, L and R to disk changes, SELECT to the virtual keyboard, and START to the menu. Holding L and R for three seconds enables mouse mode. Save states are available, though interlace-mode saves cannot be loaded. Display controls provide vertical correction from -20 to +20 pixels and stretch from 0 to 40 pixels.

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.
