BBC Micro emulator

[drd123]

Apologies if this is in the wrong forum.

I have recently switched to an iMac OS X 10.7.2 from a PC.
On the PC I used BeebEm to emulate the BBC Micro with good results.
I am having difficulty finding a BBC Micro emulator for the BBC to play games etc.

Horizon seems to be one option

but I don't understand the comment
Horizon cannot run without a copy of the original BBC Model B ROM. This is copyrighted software and thus not included with the emulator. Do not ask me to send you a copy of this file

Many thanks in advance for your help

would running a BBC emulator in the MAC via a PC emulator work??

The programmer is simply covering his/her back. You'd have to search the Internet for a copy of the ROM yourself. Obviously that would be illegal so don't.

excuse my ignorance
what is the ROM?
I thought this was a physical chip (read only memory) inside the computer itself?

It is. In most home micros it contained the Operating System - hence in this case it's the copyright of Acorn (now effectively deceased) and the BBC (definitely not deceased!).

The emulator needs a dump of the ROM in order to operate.

I think our BBC had an expansion ROM board installed in it so you could fit up to 10 ROMs. A number of office apps (as they are now) such as WordWise, AMX Pagemaker etc all shipped as 1 or 2 ROMs in addition to the program disks.

Sorry for being vague about ROMs. Good luck and please report back as I remember the BBC Micro B fondly. Not sure how I'm going to examine the contents of a 5.25 inch floppy I found the other day though...
