The available emulators are presented here (alphabetically). Some are commercial, and some are not even available.

Most emulators are available directly from the "The BBC lives!" archives. However, the original distribution sites are linked to below, when possible. If a emulator software link doesn't work below, you'll still probably find it in this archive.

    Implementation ANSI C
    Homepage here
    Hi Robert,
    Here's an update for my 'BBCmicro' emulator...
    I have finally got around to putting up a web page for my emulator/debugger:
    The first release is available - simply the 6502A CPU core, paged memory and
    a little bit of system VIA support, and includes a graphical debugging
    I would like people to try out the CPU core using the debugger and try to
    find bugs. It should handle all the undocumented op-codes and bugs too
    so if anyone finds problems please let me know at bbcmicro@qualsar.co.uk

    BBC Environment Emulator

    Emulator name BBC Environment Emulator (?)
    Version 1.01AR
    Authors Tris 'Mad' Mabbs, © 1985 BTMsoft
    Emulates BBC BASIC
    Platform Atari 520 ST
    Price Public Domain
    Supports BBC BASIC, access to ST file system, no 6502 support, limited graphics
    Approx. speed really slow
    Implementation C
    Download here

    According to Tom Seddon, this emulator is rather useless due to a number of bugs, and overall slowness (pure C implementation). It supports a maximum of 4 colors, and a maximum of 640x200 pixels (probably mono). Tom also knows of another, similar emulator for ST, written by Tim Titchmarsh, doing a not very good job of emulating the 6502 and running the original BASIC 2 ROM.

    BBC BASIC(86)

    Emulator name BBC BASIC(86)
    Version 1.00a (Windows), 4.82 (DOS)
    Authors Richard Russell
    Emulates BBC BASIC 2
    Platform Windows, DOS (x86 - works in Windows), C/PM (Z80)... any more?
    Price Windows: UKP 29.99 (inc. VAT)
    DOS: UKP 50
    Supports BBC BASIC, graphics (x86: CGA and EGA modes), sound (x86: internal speaker only), file system access, Intel assembly. May vary between versions.
    Approx. speed fast!
    Implementation assembler
    Homepage Here! (A crippled demo version is available for download.)
    The entire BBC BASIC(86) manual is available.
    Download BBC BASIC(Z80) can be downloaded free of charge.

    Because this is not a full BBC micro emulation, but rather an adaption of the BBC BASIC language for other platforms, the performance is much higher than full-fledged emulators when it comes to BASIC power.

    There are also versions for Victor Sirius and Research Machines Nimbus, but these are obsolete.

    For the DOS version, four versions are supplied on the distribution disk:

  • BBCBASIC.EXE: Small memory model (max 64K user RAM)
  • BIGBASIC.EXE: Large memory model (max 640K user RAM)
  • BBCRUN.EXE: As BBCBASIC, but 'run only' version (pseudo-compiler)
  • BIGRUN.EXE: As BBCRUN, but 'run only' version
  • BBCRUN and BIGRUN are not really compilers, but allow you to build a stand- alone .EXE file from a BBC BASIC program.

    The company which, for several years, distributed the PC version of BBC BASIC (M-Tec Computer Services) has recently gone out of business. Therefore, enquiries about the product should now be sent directly to Richard Russell (by email - see above, or fax to +44 1375 892439).

    Supports BASIC ROM, some OS calls, simple text only

    Emulator name BBCEm
    Version never released
    Authors Nigel Gilbert
    Emulates [BBC B] (6502 and text display)

    Version unreleased
    Author Adam Hamilton
    Emulates [BBC B] (plans for more)
    Platform UNIX (X/Motif) (Windows version planned)
    Implementation C

    In Adam's own words:

    The current status of the emulator is:
    6502A CPU - Virtually complete, I've included ALL undocumented
    instructions and CPU bugs.
    6522 System VIA - about 20% complete.
    6522 User VIA - not started, but shouldn't take too long after the
                    sys VIA is complete.
    Addressable latch - complete.
    Memory and paged memory - complete.
    As you can see, there's a fair way to go yet before I have anything
    to release, but I'll keep you informed.

    Version 1.02 of pcBBC includes the following new features:
