Jaguar Virtual Video-Game

Project site updated

2009-08-08T17:52:00.002-03:00

I've updated the project's web-site. There you can find the full binary package of the JG40 Assembler and the JG40 Emulator, including examples and 3 "full" games. :P
Check it at: http://dgm.6te.net/
I'm looking forward to see if anyone gets interested in coding a game for my JG40, and I'll post the full source-code of the assembler and emulator if I am requested to.

Long time since my last post, again. :)
Well, I finished the emulator. Long time ago, in fact. Everything works fine, as it is supposed to do. I made some examples and a "full game".
I'll soon post the full package of this emulator, including source-code, for those who are interested. :)

The Jg40 emulator

Whoa! Long time since my last post! I've been busy because of the college :D
Ok, I'm doing pretty well with the emulator, as I said I've done the CPU emulator and now it emulates the video part as well. The CPU emulator had some bugs, all of them corrected by now (may have others hehe). Ah, I'm using SDL to the emulator.
Well, the project's still alive. I'll post all the source-codes when I finish it. (All in plain ANSI/C, so I can compile in many platforms.)

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

2007-08-20T02:20:00.000-03:00

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

2007-08-01T02:16:00.001-03:00

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

2007-07-29T18:01:00.001-03:00

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

2007-07-29T17:57:00.000-03:00

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.
