BeebEm is a BBC Micro and Master 128 emulator. It enables you to run BBC Micro software on your PC. BeebEm was first developed for UNIX systems in 1994 by David Gilbert (Dave's page) and was then ported to Microsoft Windows.

To run the latest Windows version of BeebEm you will need Windows 98 or later. The UNIX version will run on most UNIX based systems and Linux (the Windows version also runs quite well on Linux under “wine”). The full source code for BeebEm is included in the downloads.

BeebEm will run most BBC Micro software including Elite, Exile and Revs. It will also run most BBC Micro ROM software (e.g. Wordwise).

The software page has links to sites where you can download software. You can also download OddJob, a previously unreleased game for the BBC Micro.

Improved IOC mapping, improvements on !PCem, NetBSD etc
ArculFS now read/write, and now ROM based
Sound improved a little
Can now disable all video borders
SWPB now works, also corrected SWP and MUL encoding - Fire & Ice now works
Return of FDI support
ADP protected disc image support
FDC improvements
High-res mono monitor emulation (1152x896)
A3010 joystick emulation

XRoar v0.26 Changelog:
* SAM-VDG interaction fix - 48 byte-per-line mode now works.
* More resilient fast tape loading.

- Added support for Winchester drives.
- Documentation rewritten in LyX rather than plain text.
- Bug fix: Screen corruption in FP and F1 video drivers under certain circumstances.
- Bug fix: FP colour display now properly handles scrolling using the CRTC base registers.

The CPU named CSG 4510 R3 (codenamed Victor) was a custom CSG* 65CE02 (a MOS 6502 derivative), combined with two MOS 6526 complex interface adapters (CIAs)
3.54 MHz clock frequency (the C64 ran at 1 MHz)
A new VIC-III graphics chip named CSG* 4567 R5 (codenamed Bill), capable of producing 256 colors from a palette of 4096 colors; available modes include 320×200×256, 640×200×256, 640×400×16, 1280×200×16, and 1280×400×4 (X×Y×colordepth i.e. number of colors/bit planes)
Supported all video modes of VIC-II
Textmode with 40/80 × 25 characters
Synchronizable with external video source (Genlock)
Integrated DMA-Controller (Bit blit)
Two CSG* 8580R5 SID sound chips producing stereo sound (the C64 had one SID)
Separate control (left / right) for volume, filter and modulation
128 kB RAM, expandable to 8 MB using a RAM expansion port similar to that of the Commodore Amiga 500
128 kB ROM
Heavily improved BASIC: Commodore BASIC 10.0 (the C64 had the relatively feature-weak BASIC 2.0, which was almost 10 years old by this time.)
One internal 3½" DSDD floppy disk drive
Keyboard with 77 keys and the remote cursor block
(* CSG = Commodore Semiconductor Group, previously known as MOS Technology, Inc.)

Hi65 v1 Changelog:
* It can load programs at launch time, by specifying the name of the program as a parameter in the command line
* It can load programs at run time, by using the DLOAD command
* It can run a consistent subset of BASIC 10 instructions, although, for now, mathematical expressions need to have at most one operator
* It can perform extremely fast graphical operations, with an accuracy and speed exceeding those on MESS or on a physical Commodore 65 of various orders of magnitude.
