UAE4ALL2 HD Vita vs UAE4ARM

UAE4ALL2 HD Vita is a free, open-source PlayStation Vita build of an Amiga emulator based on UAE4ALL2. It emulates OCS, ECS and AGA chipsets with 68000 and 68020 CPU modes, covering Amiga models from A1000 through A4000, CD32 and CDTV. Supported media include ADF, ADZ, DMS, IPF, ZIP, LHA, LZH and HDF files, plus CD32 CHD, ISO, BIN, CUE and M3U images. WHDLoad can extract archives, configure an A1200 profile and launch games. An HDF Manager creates FFS images from 50 MB to 8192 MB, with four slots; a single Amiga partition remains limited to 4 GB. The app offers save states, a game library with up to eight roots, shaders, aspect scaling, touch and analog mouse controls, a virtual keyboard and autofire. FTP exposes Vita partitions on port 1337 and is unencrypted. Users must supply legally obtained Kickstart ROMs and disk images. UAEGFX/Picasso96 is not enabled.

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.
