Jammy vs UAE4ALL2 HD Vita

Jammy is a free C# Amiga emulator for Windows and Linux that aims to run Workbench, games, and demos. It lists support for A1000, A500, A500+, A600, A1200, A2000, A3000, A4000, and CD32 models, with OCS, ECS, and AGA emulation. It emulates components including the Copper, Blitter, CIA, sprites, playfields, and audio. Supported floppy image formats for reading include ADF, zipped ADF, ADZ, DMS, and RP9; ATA hard disks support reading and writing. Development tools include a debugger, disassembler, automated code analysis, and SQLite storage for disassemblies. JavaScript and Lua APIs can run code on breakpoints, and a web API supports custom user interfaces. The releases page lists Windows Alpha and Linux Alpha release 0.0.30. The project reports DMA timing problems, incomplete cycle accuracy, poor emulation of CPUs above 7 MHz, and software that does not yet work. CD32 CD-ROM and NVRAM do not work, the IPF floppy reader is broken, and there is no ARM build. Linux lacks debugging interfaces, and its scripting, web, and database APIs need more work.

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.
