JG40 CPU emulator

Well, yesterday I started (and finished) to write the JG40's CPU emulator. As you should have seen on the specifications, it's very simple. Now I'll start to work the video/sound/controller part of the emulador.
I will post the source-code as I finish it.

JG40 simple assembler

I've finished the JG40's Assembler.
It's a very simple assembler, with some features: includes a maximum of 256 files, binary/hexadecimal/decimal notation, labels, symbols, organization, data declaration (dn/db), binary file inclusion.
You can get the source-code here:

JG40 Assembler source-code

Now, I'll start to work on the emulator! Yay! :D

New mini-project

Well, I started a small project. A small brother of Jaguar, a 4-bit handheld. Here you have its specifications:

JG40 Specs

I intend to learn the common traps and pitfalls in this smaller project before I go on with its more powerful 8-bit brother. The jg40 assembler is almost done, I'll post it here when I finish.

Main aspects

Well, I've made the principal aspects of the Jaguar.
You can see them here:

The Microprocessor

The Memory Organization

The other aspects, like Video and other stuff are already done, except the Sound, but I'm reviewing it.

Introduction

Hello, my name is David, aka DGM.
I like old 8-bit/16-bit video-games, like NES, Sega Master System, Mega-Drive and so on. So I decided to start making my own. I will call it Jaguar. Hey, I just like this name, and it has nothing to do with Atari Jaguar.

Jaguar will be a virtual hardware of a gaming console, consisting on an 8-bit microprocessor with a very reduced instruction set, video, sound and input controllers.

I am planning all this stuff based on my studies around other vintage old video-games, like NES and Mega-Drive. But it is a totally "new thing". Neither I have the pretension of making it like would do a hardware engineer, nor I could. I'm just trying to do it just as "real" as possible.
