Gerard: 13-Jun-2012 | While dreaming about the next best thing coming from the Red community ... here are some IDEs for ARMs processors http://www.ti.com/lsds/ti/dsp/support/dev_tool/ccs_overview.page and then some emulators and analyzers http://www.ti.com/lsds/ti/dsp/support/emulator_analyzer_overview.page | |
DocKimbel: 15-Jun-2012 | @Gerard: I will try it under 3.1 in the emulator. | |
DocKimbel: 15-Jun-2012 | @Gerard: works under emulator with 3.1, the kernel version is much lower though than the one you've reported, I have 2.6.29 here. | |
Gerard: 15-Jun-2012 | @Doc : Thanks for the try of the emulator - Now installing the Android update for my - almost 50 % left to do after 30 minutes - for an 88 MB download - !!! I will retest after everything is completed... | |
Kaj: 26-Dec-2012 | BREAK/GOTO/FSM: I also try to avoid BREAK, although it can come in handy. GOTO would make my 6502 emulator faster, but it's ugly. Having FSM support would be brilliant | |
Kaj: 16-Jan-2013 | Arnold, Red/System has been ready for writing code for at least a year. Red is only getting to that stage now, so that's why I have been working in Red/System. My 6502 emulator is a major self-contained work in Red/System, but there's also the issue of communicating with the outside world. Unless you write your own operating system, the way to do that is by binding to the existing operating system | |
Kaj: 8-Feb-2013 | Have you seen my 6502 emulator in Red/System yet? :-) | |
Bo: 8-Feb-2013 | I saw that you wrote a 6502 emulator, but haven't had time to look at it yet. Sounds like a fun project! | |
DocKimbel: 9-Mar-2013 | Kaj: do you see the content there: http://transmog.net/iphone-simulator/mobile-web-browser-emulator-for-ipad-2.php?u=https://trello.com/board/red-programming-language/51387ada4e1ba9b86b001141 | |
Kaj: 9-Mar-2013 | If I go to syllable.org in the emulator, our site flashes by and then that screen goes blank, too, so that emulator is broken, too | |
Pekr: 17-May-2013 | uf, installed AndroidStudio and built first example for emulator. Pretty complex stuff, hidden under nice roof :-) | |
DocKimbel: 8-Jun-2013 | Got a simple HelloWorld text displayed in an Android native window using the emulator with an x86 image. Working on the ARM version now. | |
DocKimbel: 8-Jun-2013 | Ok, works fine from ARM emulator and Android 2.3.3. | |
DocKimbel: 9-Jun-2013 | Pekr: you can test it here: https://www.manymo.com/emulators But the Hello app exits immediatly, not sure it's a bug or related to their emulator. | |
DocKimbel: 9-Jun-2013 | Yes, but I'm not sure why as it works fine on 2.3.3 and 4.2.2 on the emulator and 2.3.5 on my HTC. | |
DocKimbel: 9-Jun-2013 | I wonder if they use x86 emulator images instead of ARM ones...would makes sense performance-wise. | |
DocKimbel: 9-Jun-2013 | It's one for the x86 version of the emulators (you need Intel Atom images) and for Manymo (the online emulator). | |
DocKimbel: 12-Jun-2013 | I just tested the hello.apk (downloading from the Red site) on an emulated 4.2.2 and it works fine. So, it looks like the Android emulator is not as reliable as it seems. | |
DocKimbel: 17-Jun-2013 | Notice that this runs on the x86 emulator, there's still a few bugs to fix for the ARM version. | |
DocKimbel: 24-Jun-2013 | Actually it does even on your 4S using iAndroid emulator: http://www.youtube.com/watch?v=gehh6zIijXM ;-) | |
Kaj: 25-Jun-2013 | There's a binary example in my 6502 emulator, where it loads a ROM file | |
Kaj: 25-Jun-2013 | I updated the 6502 emulator to use it, so you can see an example there | |
DocKimbel: 27-Jun-2013 | But that won't work with the apk you've buit, that online emulator requires x86 code. | |
DocKimbel: 2-Jul-2013 | Maybe Pekr could do an Android Red app compilation + execution on the online emulator short video too? If it includes one of your nice models from the photo studio, that would be even better. ;-) | |
DocKimbel: 21-Jul-2013 | I'm upgrading from 3GB to 12GB, I kept having "out of memory" error after opening a few dozens web pages and starting some heavy tools like Eclipse, Android Emulator or various VM...now I should be able to run everything at the same time. ;-) | |

Kaj: 10-Dec-2012 | Here's a 6502 CPU emulator written in Red/System: | |
Kaj: 10-Dec-2012 | However, I rewrote it from a fairly complete Atari XL/XE emulator that I did in C a long time ago. The new code is a third shorter, mostly due to abundant use of preprocessor macros, which are less horrible in Red/System than in C | |
Kaj: 10-Dec-2012 | In this new emulator, I abstracted the machine emulation from the CPU emulator, so that different machines could be implemented using the same CPU emulator | |
Kaj: 10-Dec-2012 | My full Atari emulator ran full speed on a Pentium 75 or a 100 MHz 486. I roughly expect this one to run half as fast, so as a full emulator I'd expect it to need a Pentium 150. As another guesstimate, it should need half a Raspberry Pi | |
Kaj: 23-Dec-2012 | My 6502 emulator in Red/System now takes the name of a ROM file as a command line parameter. It can load any ROM that's a multiple of 2 KB in size: | |
Kaj: 23-Dec-2012 | I've added binaries for all systems to my test repository, so you can now easily try the emulator if you have some ROM from the golden days: | |

Pekr: 10-Dec-2012 | Hasn't someone written 6502 emulator for REBOL too? Was it Geomol? It would be nice to compare speed-wise :-) | |
Kaj: 10-Dec-2012 | Doc, it's firmly an 8-bit CPU emulator, but it can certainly serve as a general example to implement other emulators in Red/System | |
Kaj: 10-Dec-2012 | Hm, John's emulator uses RebCode, perhaps that's why it slipped my mind. It would be fairly fast, but only runs on some REBOL versions | |
GrahamC: 14-Jan-2013 | Yes, but that's a 6502 emulator ... not really what I want! And the other thing was called "empty.exe" which doesn't seem to do anything | |

Dockimbel: 1-Jun-2005 | Does anyone know if REBOL runs on Windows CE.NET 4.2 ? I'd need to use REBOL on that platform but I don't have access to a CE.NET terminal and can't use an emulator because there's no REBOL WinCE x86 binary. | |
Geomol: 1-Apr-2008 | 6502! :-) You may wanna check out my 6502 asm and emulator written in REBOL: http://www.fys.ku.dk/~niclasen/rebol/language/ | |
Steeve: 18-Dec-2008 | in fact i remember having to simulate a goto command when i tried to develop a Z80 emulator. i had build a simple engine working like that: code: [ [ some code....] [ some code...] [ some code ... GOTO: 1] ; goto the first line of code ] GOTO: 0 forever [ GOTO: GOTO + 1 do pick code goto ] | |

Cyphre: 16-Apr-2010 | Well, if you are able to make at least script that is able to crash (even randomly) I can test it here on external agg dll DRAW emulator to see if the porblem is in AGG code itself or if it is on the rebol dielaect side. | |
Group: Parse ... Discussion of PARSE dialect [web-public] | ||
Gregg: 3-Feb-2008 | James is getting into Forth, and I was just looking at some old notes I made on ForthR (play on "further"), where the machine primitives are actually a little REBOL VM/emulator, rather than ASM for a specific chip. Easier to get started, though not real Forth. | |
Graham: 4-Feb-2008 | I have the figforth assembly code for the 6502 ... so you could run fig forth on your 6502 emulator ? | |
Geomol: 4-Feb-2008 | I'm not really sure. First I do a general 6502 assembler and emulator, but I only have an emulator of the BBC homecomputer to test up against, so I probably have to deal with some Operating System stuff too. I operate with a 64k address space, and on the BBC writing to some certain addresses made something special for that platform happen. But let's see, what we can do. | |
Henrik: 4-Feb-2008 | slightly off topic: who was it that wrote a z80 emulator with embedded space invaders? | |
Geomol: 5-Feb-2008 | You see, now I have a 6502 assembler written in REBOL, so now it will be easy for me to test a 6502 emulator, while I'm writing it. | |
Robert: 8-Feb-2008 | Is there an emulator for this Elite release? | |
Geomol: 8-Feb-2008 | Robert, there's no emulator written in REBOL, that can run Elite, afaik. But there are emulators emulating the BBC computer, if that's what you mean, and they can run Elite. I use an emulator called BeebEm3. | |
Group: Syllable ... The free desktop and server operating system family [web-public] | ||
Kaj: 3-Sep-2005 | Yes, you can install on an extra partition. Same way as you could install in an emulator: you need to download the base Syllable package instead of the CD | |
Kaj: 22-May-2006 | 5 Core developers, maybe 50 that have contributed at some time, 500 on the mailing list, more than 1000 on the forum, 5000 who download each install CD, more than 10,000 who download each live CD and emulator image, tens of thousands who come visit when we're on OSNews, roughly an order of magnitude more when we're on Slashdot | |
Kaj: 5-Mar-2007 | It should be possible to run some version in some emulator, but I haven't done it yet. We've only had Bochs running in the past. We're still having some problems porting QEmu, but we're looking into it | |
Kaj: 6-Oct-2007 | But I could do a slideshow when I prepare an emulator image] | |
Kaj: 17-Oct-2007 | We created a bunch of virtual machine images, so you can try Syllable Server easily in an emulator without installing it: | |
Kaj: 17-Oct-2007 | http://osnews.com/story.php/18774/Syllable-Server-Emulator-Images | |
Kaj: 21-Oct-2007 | Meanwhile, I would be interested in feedback from people who have the guts to actually install Syllable Server, or even just run one of the emulator images, so they can comment on the system itself | |
Kaj: 13-Dec-2007 | I thought the Syllable screenshot running a DOS emulator running my Atari 8-bit emulator running a Boing ball demo in the Amiga group here would be a giveaway :-) | |
Kaj: 10-Jan-2008 | The OLPC with AmigaOS is just their own Linux with an Amiga emulator on top. That's easy to install | |
Kaj: 15-Sep-2008 | I still have to make an emulator image for Server 0.3, so I'll see if I can port Dovecot before that | |
Kaj: 17-May-2009 | Many bugs were fixed, including several regressions from earlier releases. The window decorators don't destabilise the system anymore. The installation procedure is greatly enhanced with options to fix hardware support problems. The native web browser is replaced with Webster, based on a newer version of the WebKit engine. Many enhancements were made to standards support, leading, among others, to the ability to run QEmu - so now you can run virtual machines. The documentation was improved and several translations were added. Read more in the full release notes: http://downloads.syllable.org/Syllable/i586/systems/Desktop/0.6.6/README-SyllableDesktop-0.6.6.txt ISO CD images, (VMware) emulator images, an upgrade pack and documentation are available from the download page: http://web.syllable.org/pages/get-Syllable.html Extra software is available here: http://web.syllable.org/Syllable/downloads.html | |
Kaj: 30-Aug-2011 | Ah, I must have forgotten about that. Is the emulator based on an x86 version? | |
Kaj: 30-Aug-2011 | Onetom, Henrik had Syllable working on VirtualBox in January here above. Other people have reported failure with some VirtualBox and VMware versions. You have to follow the right procedure, and then it still depends on emulator versions | |

Steeve: 17-Jun-2008 | I got the data using a free MSX emulator (openMSX). The music come from the game "Auf wiedersehen Monty". You can use a "dump PSG" functionality in openMSX to get the raw data (values of the registers of the PSG). You can find lot of roms (games) for the msx wich contain cool musics and effects for the AY PSG on www.planetemu.net Beware, these roms are not freeware even if you can download them freely. Another way (i have not tried), is to use VortexTracker at http://bulba.at.kz/ (see http://www.youtube.com/watch?v=lYdIqcqgkPMfor a demo) wich is well designed to compose an manipulate raw data for the AY-* PSG. I think many samples are given too. | |

Graham: 27-Feb-2007 | hey, what about a 6502 emulator ?? | |
Geomol: 11-Feb-2008 | Here's a MOS 6502 emulator written in rebcode, I made over the last few days: http://www.fys.ku.dk/~niclasen/rebol/language/em6502.r | |
Geomol: 11-Feb-2008 | Those 4 lines do this: load the assembler, load the emulator, call the asssembler with a 6502 asm program returning 64kb ram, and finally run the program. | |
Geomol: 11-Feb-2008 | Not much to see, but the program ram. To check things, put e.g. print lines in the end of the emulator. Like those 2 already in there commented out: print A print P which will print the content of the A register and the P (status) register. | |
Geomol: 11-Feb-2008 | Just to clear things out regarding performance. This is an emulation of a 1MHz cpu. It requires quite some computing power to emulate another cpu. To give a hint: an instruction line INX, which increment the X register by 1 requires 2 cycles on the 6502. So you can do half a million of those instructions on a 1MHz 6502 each second. In my emulator, that INX instruction become 11 rebcode instructions plus 6 rebcode instructions to control the loop, a total of 17 rebcode instructions. And it takes less than half a second to do 1 million of those, which is like a 4MHz 6502. So with this initial test, I'll say, rebcode is useable. | |
Geomol: 12-Feb-2008 | A first version of a MOS 6502 workbench tool is ready: do http://www.fys.ku.dk/~niclasen/rebol/language/m6502wb.r It'll load the 6502 assembler and emulator. It's a tool to compile 6502 assembler programs to machinecode and run it with the rebcode emulator. It's possible to see the 6502 registers and flags. Both asm6502.r and em6502.r has been updated. | |
Geomol: 12-Feb-2008 | It works like this: 1) Write some 6502 asm in the text area. Example: lda #&80 2) Press the button "Assemble". Now you can see the opcodes in the ram at address 0000. 3) Press the button "Begin" to run the emulator with the produced machine code and see the results in the registers and flags. | |
Geomol: 12-Feb-2008 | A performance test program: lda #0 sta &1001 .l1 lda #0 sta &1002 .l2 lda #0 sta &1003 .l3 lda &1003 adc #1 sta &1003 lda &1003 bne l3 lda &1002 adc #1 sta &1002 lda &1002 bne l2 lda &1001 adc #1 sta &1001 lda &1001 bne l1 It takes 40s to run on a BBC emulator emulating a 1MHz 6502. It took around 14s using the rebcode emulator on my 1.2 GHz G4, and it took 9.5s using the rebcode emulator on my 2.4GHz Pentium 4. | |
Geomol: 13-Feb-2008 | There's something wrong with my compare with a 1MHz 6502. I counted the number of cycles in the inner loop and found 17 cycles. A 1MHz 6502 can then do 1'000'000 / 17 * 40 = 2'352'941 loops in 40 seconds. But the BeebEm emulator made 16.7 mio. loops in that time. It should have taken 285 sec. So programming in rebcode is more like a 107 MHz cpu in this test. (It's probably not correct to measure it this way.) | |
Steeve: 13-Feb-2008 | Geomol, i had a look on your emulator code, i think perfs could be improved if you delay the update of all flags only when they are used. | |
Steeve: 13-Feb-2008 | in fact the engine is very similar with the z80 one, i think we could make a meta-emulator using external data-sheets (one for 6502, one for Z80) | |
Steeve: 13-Feb-2008 | i' made a Z80 emulator using rebcode (not complete), you can see it in galaga.r on rebol.org | |

JaimeVargas: 15-May-2007 | Gabriele, "brainfuck is turing complete, but don't tell me it's the same as scheme". Well it depends on what you mean by sameness. I am using Turing Complete as the base of the definition. Because if the language is Turing Complete you can construct an emulator of any other language. After all that is needed is bits, memory and register to carry out any computation. It maybe hard to make a Rebol interpreter in brainfuck but it is certainly possible. | |
Sunanda: 17-Nov-2007 | I remember when Pentiums were the new Black, it was said the Colossus emulator (in C under windows, I guess) was far slower than the real thing (specialist hardware designed for the task on a war economy budget). Looks like better languages, more modern hardware and (crucially) more recent algorithms means the Colossus can be finally retired: http://www.theregister.co.uk/2007/11/16/german_code_breaker_defeats_colossus/ | |
Kaj: 23-Apr-2011 | As I said, I haven't started with EC2 yet. I'd have to port Syllable Server to EC2. Syllable Desktop is impossible to run on EC2, unless you'd run it in a full emulator | |
