Ken, No Intellivision emulators directly emulate the SP0256-AL2, because that is not the chip used in the Intellivoice. In principle, they could emulate the...
Nostalgia does not support IVoice at all, yet. It's one of those things I'm getting around to. I'd like to do it from scratch as a learning experience. Lots...

Hey, guys. I have some pretty exciting news. Well...exciting to me, anyway. Take a look at the first few shots of my latest Intellivision emulation project,...
WOW! I for one am very impressed to see this! Out of curiosity, what kind of hardware do these kind of things have as compared to the desktop computers we use...
Kyle, nice work. I know nothing about developing for cellphones, however. Care to give us some specs, such as processor speed, language used, etc.? What...
Sweet! Looks great, Kyle. I just got an iPAQ, and was wondering to myself how hard it'd be to port to Pocket Windows 2003... I agree with the others, let's...

Pretty sweet! Good job dude! ... From: kyle-davis@... To: intvprog@yahoogroups.com Sent: Thursday, May 20, 2004 3:37 PM Subject: [intvprog] New...
Thanks! The phone is a Motorola V600 running the emulation in a Java 2 Micro Edition (J2ME) virtual machine. Most of these new cell phones support J2ME, and ...
It's written in Java. There's no native language that I can use that will be cross-platform (excluding a small number of Symbian-enabled cell phones). I'm...
I can think of many ways to greatly improve the performance of your emulator. First of all, if you haven't yet, check out my Intellivision for Game Boy...
Carl, Very good suggestions indeed, although not all apply to a Java based emulator. The biggest suggestions that'll help Kyle are: -- Losing the cycle...
Kyle, This looks very nice. Great job! Now about the possible optimizations, I think the following questions have some importance: - What is the most expensive...
All, Speaking of emulators on underpowered hardware ... I'm working from time to time on an Intellivision emulator for the Atari ST. This project is however...
... For the EXEC, you could always have a predecoded image of what EXEC loads into RAM, since it's fixed. In general, if you wanted to support self-modifying...
... Yes, that's more or less what I'm planning to do. ... Agreed. But that would have a slight CPU cost, anyway. So, I'm not sure it's worth doing that. As far...
... I'm sure you knew you were going to hear from me, Arnold. :-) Of Course, I think you can definitely do it. If I can get an emulator to function at full...
... Sure! As a side note, "Arnauld" is pronounced "Arno" in French, not "Arnold". Not that I really care about the way you write it or pronounce it, anyway....
All, Assuming that opcodes are pre-decoded before execution, it's possible to create some specialized routines. I think I'm going to try that. Some existing...
... I had this same idea, and after some testing, found that it was not a worthwhile optimization. Basically, specific combinations do not occur frequently...
... Ok. That makes sense. ... Yes, that's also what I'm doing. However, I could go a step further and precompute immediate values on 16 bits (see below) rather...
Is there a document out there that explains the EXEC calls? I looked in the DeReIntellivision but it is minimal. I could not find anything in the SDK docs. ...
... There are two things you need: -- Your Friend the EXEC. This document describes the programming model for the EXEC. -- A list of entry points. YFTE...
All, Something I've been meaning to post for awhile... Below is a disassembly of the Intellivoice's ROM. This might be useful to anyone wanting to emulate the...
David... I agree that the EXEC documentation is very minimal. The best source of information I have come across is a document which contains the disassembled...
... The package can be found in the 'Files' section of this list. Just look for 'dsm1600.zip' here: http://groups.yahoo.com/group/intvprog/files/ -- Arnauld...
We are releasing our first official single "The Future" on June 21. The CD features a new version of the song plus 3 new tracks, including "Bomb Squad"...
