Free emulator software for linux

Mamory is a set of usefull functions for emulators related projects.
Mamory project allows easy inclusion of roms management features into these projects through a simple API.
The distributed packages also contain a command line interface that use the potential of the library libmamory.so.
Enhancements:
- The embedded expat library has been removed: this release requires that expat is installed on your system.

plus4emu is a portable emulator of the Commodore Plus/4 computer. It supports Windows and POSIX platforms (32 bit Windows and 32 and 64 bit Linux have been tested).
The project implements accurate, high quality hardware emulation, but the system requirements are higher than that of most other emulators.
Enhancements:
- TED emulation improvements were made.
- The frame rate in full speed mode is now limited to a maximum of 50 Hz to improve performance.
- Some minor bugs were fixed.

MESSyFront is a frontend for the MESS emulator. MESSyFronts main goal of the project is to get the user in to the emulation environment as quickly as possible.

The secondary goal is targetting Tandy Color Computer users that run Linux (or *nix envrionments). As interest grows, other target environments may be added.

LIBDSK is a library for accessing discs and disc image files. LibDsk is intended for use in:
- Emulator tools - converting between real floppy discs and disc images, as CPCTRANS / PCWTRANS do under DOS.
- Filesystem utilities - CPMTOOLS is configurable to use LIBDSK, thus allowing the use of CPMTOOLS on emulator .DSK images. To do this, install LIBDSK and then build CPMTOOLS, using "./configure --with-libdsk". For CPMTOOLS 1.9 or 2.0, you will also need to apply this patch.
- Emulators - it is possible to use LIBDSK as part of an emulators floppy controller emulation, thus giving the emulator transparent access to .DSK files or real discs.
LIBDSK has drivers for:
- Raw files (including /dev/fdn).
- .DSK files, as used in CPCEMU, JOYCE and other Sinclair/Amstrad emulators.
- MYZ80 hard drive image files.
- NanoWasp floppy image files.
- .CFI (Compressed Floppy Image) files, as created by FDCOPY.COM under DOS.
- The Linux floppy drive (supports CPC System and Data formats, which the standard "Raw file" driver does not).
- The Windows 3.x/95/98/ME/NT/2000 floppy drive.
- The DOS floppy drive (via the PC BIOS).
- CopyQM files (read-only)
- APRIDISK image files
- rcpmfs - a backend that makes a Unix/Windows directory appear to be a CP/M disc image.
- Another instance of LibDsk over a serial line.
Enhancements:
- Two new disc image formats (logical and teledisk) and one new disc geometry (TRDOS 640k) have been added.

termit is a simple terminal emulator based on vte library.
Main features:
- tabs
- bookmarks
- changing tab name
- changing font for tabs
- encodings (all available from GTK2)
Configuration can be changed via $HOME/.termit file (example is provided).
Enhancements:
- Calls to getenv were replaced with g_getenv.
- A possible double free was fixed.

XRoar is an emulator for the Dragon 32, Dragon 64, and Tandy Coco2 computers all originally released in the early 80s.
The emulator runs under Unix-like OSes (using SDL for video and OSS for audio) and the GP32 handheld gaming device.
Enhancements:
- Fixed resizing and border alignment in OpenGL video module.
- Virtual floppy timings more accurate.
- JVC (".dsk") virtual disks supported.
- Preliminary CoCo disk support (some stuff works, NitrOS-9 doesnt).
- 6809-PIA interrupt interaction more accurate (fixes some games).
- Various command-line options added.
- CoCo can operate with or without Extended BASIC and Disk BASIC ROMs.

GNOME FCE Ultra (also known as gfceu) is an interface for the popular Nintendo Emulator, FCE Ultra. GNOME FCE Ultra is designed for the GNOME desktop, and allows the user to easily play NES ROM images.
Main features:
- Network play
- Custom input configuration
- Fullscreen support
- Full sound support
- High compatibility and accurate emulation
