Copperline vs UAE4ALL2 HD Vita

Copperline is a free, open-source Amiga emulator for games, demos, and development, available on Linux, macOS, Windows, and in browsers. It models OCS, ECS, and AGA machines with 68000 through 68060 CPUs, plus expansion boards, hard disks, and CD drives. Its Debug workspace puts registers, disassembly, and memory beside the Amiga display, and supports reverse stepping from snapshots. Development features include scripted inputs and captures, repeatable test sessions, headless runs, a JSON-RPC control protocol, and debugging Amiga source code from Visual Studio Code. Rollback netplay supports two players on desktop or in browsers, up to four desktop players with the four-player adapter, and up to eight spectators. A libretro core supports RetroArch, including A500, A1200, and CD32 software, WHDLoad, playlists, save states, four local controller ports, and RetroArch netplay. Copperline includes the AROS Kickstart replacement, though some software needs an original Kickstart ROM. It does not support high-density Amiga floppy images or sector-based PC/CrossDOS images.

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.
