GEKKO Amiga Emulator vs SF2000-UAE

GEKKO Amiga Emulator is a free Android app that emulates Commodore Amiga systems. Its listed emulation covers Amiga graphics, floppy-drive behavior, and hard-disk behavior. Controls include mouse input, virtual mouse controls, and joystick switching between ports 1 and 2. Bluetooth joypads are supported. The app listing describes fast loading and a Force 256 display-aspect option. Users can use a command line to insert text or press a key. GEKKO links to an Android version on Google Play, where the app is listed at free and contains ads. Google Play gives it an Everyone content rating. The developer is named as Gennaro Coda, with an address in Gragnano, Italy, and support is available at [email protected]. The developer’s privacy policy says its apps and games do not collect information. Google Play separately says the app may share device or other IDs with third parties, collects no data, encrypts data in transit, and does not allow data deletion.

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.
