It's been almost four years, and I decided it was about time to dig this all up and release it. It's collected quite a bit of dust on my hard drive and will need a little tweaking to get it working again, but it's almost all there.

The Devtendo hardware requires both the communication software for the NES and PC. The package just released includes the full source code. It will need a few tweaks as some stuff is hard coded, but otherwise is good to go.

NES cartridges can be read/written with it, and the software supports many different mappers. In addition, I built a Game Boy adaptor, so the software even supports GB carts fed through the NES!

You should now have everything you need to make and use your own Devtendo (with a few tweaks)!  [View]

I'm finally getting around to sorting through my old unreleased dev stuff and putting it up here! A special thanks goes out to the people who emailed me about this stuff, without them I probably would've never gotten around to releasing it, and it would've all bit-rotted on my hard drive :)

On that note, let's start the releases with a bang! The Devtendo Schematics!

They should work just fine, but as it's been so long, I can't remember if I made any changes while building it. It's only a list of the chips/connectors and their connections, but the other small components should be quite straight forward. Good luck!  [View]

Immediately after the original GBlinkdl, I whipped together this GB hardware modification which eliminated the need for the cartridge swap. However, I didn't get around to updating the site until now! Oh well, better late than never! Here it is...

The GBlinkdl DevBoy is an extension of the original GBlinkdl project, which required no hardware modification. The DevBoy eliminates the need for cartridge swapping and gives full development control of the Game Boy from the PC. It uses the same simple 4-wire cable between the Game Boy's link port and PC's parallel port, allowing for the two devices to communicate with each other. It also uses the same GBlinkdl.exe program as the simpler version. Just as the original GBlinkdl, it gives you the ability to write to a flash cart, dump cartridges, read and write save data, probe the GB, reverse engineer mappers, and more... but this time without the need for cartridge swapping or the use of a Game Genie.

The PC program also has been updated to support more MBC types, and is compatible with the old GBlinkdl!

You can download the GBlinkdl DevBoy package here (55KB). It includes everything you need to take control of your GB from your PC, as I've included the full source code to the PC and GB programs and schematics. Have fun!

I have put up an in depth look at the Hong Kong original version of Super Mario Bros. 3 for the Game Boy/Color.

It includes a review, loads of screen shots, techincal information, a mapper patch, and information on how to dump it!

I present the first of a number of updates! GBlinkdl!

GBlinkdl uses a simple 4-wire cable between the Game Boy's link port and PC's parallel port, allowing for the two devices to communicate with each other. By running GBlinkdl.gb on a flash cart and GBlinkdl.exe on your PC, you can read and write the Game Boy's memory and registers from the PC. It gives you the ability to write to a flash cart, dump cartridges, read and write save data, probe the GB, reverse engineer mappers, and more... all without any hardware modification!

I originally built this to dump some cartridges before they suffered from bitrot, and some other obscurities, including the Super Mario 3 Special HK Original. The busier I get, the more I'm about simplicity, or more specifically, taking the best approach which can be done in the least possible time. Building a GB cart dumper with the features I wanted would've taken more time, and I already had the link port<->parallel port cable handy from my flash kit, the 'PC Linker'. As well, because this goes through the real Game Boy, the mapper and such is written to directly as it is under normal execution.

You can download the GBlinkdl package here (52KB). It includes everything you need to take control of your GB from your PC, as I've included the full source code to the PC and GB programs and the cable schematic. Have fun!

NESHLA has been released!

I've finally released NESHLA, the high level, open source, 6502 assembler for the Nintendo Entertainment System! I've put it up on sourceforge with it's full source code. The project site is at: http://www.sourceforge.net/projects/neshla, and the documentation at http://neshla.sourceforge.net.

The assembler is packed with features, macros, functions and header files to make development quick and easy. It does the job, and has made my development on the game Grand Theftendo much easier. However, there is still room for an endless amount of features, tweaks and additions. That's where you come in! Anyone interested in joining the project and contributing is more than welcome! It's written in standard C and should compile and work on any platform with little or no modification. So whatever platform is your choice for development, you can help out!

I had planned to release it after Grand Theftendo, but because I have been so busy with work, I have much less time to work on this software than I used to. I have made it open source with the hope that everyone with the interest will join in and help bring NESHLA to it's full potential!

With all the news about the upcoming handheld, the Gizmondo, I became reminded of the old handheld from eight years ago, the Tiger Game.com. It's appearently not the same Tiger developing it, thought I'm not sure if that's the only reason it reminds me of it, heh.

With this recent reminder, I decided to take a little time to dig into the little known handheld and have whipped together some pages with my findings. Of the findings include details on how the LCD and video signal work, along with pinouts.

As a bonus, with my new video capture device adaptor, I've taken nearly a hundred screen shots of Game.com games. Have a look and see what games you could have been playing eight years ago *laughs*!

Building the extendable Video Capture Device 2 with the ability to work on a wide variety of systems, you must have figured I had more in mind than just the Game Boy! You were right. I've built another adaptor for it, this time for the Tiger Game.com! Have a look, and see the games in all their... glory?  [View]

I've completed my latest gizmo, the Video Capture Device 2! The Video Capture Device 2 is a data sampler which, when clocked, stores an incoming stream into SRAM chips. The data on the RAM can then be read by a connected PC, and in the case of a video stream, displayed through it. It is the next step from the original Game Boy/Game King Video Capture Device, and supports much more, including 16-bit video.

This versatile device can be used on many different systems with simply an adaptor. So far, I have done adaptors for the Game Boy Pocket and Game Boy Advance! More will come eventually!

Simply put, it allows you to play your GBA on your PC monitor!  [View]

Here's another MMC5 document... the ROM pinouts! I posted these back on the old NESDEV message boards a while back, but here they are, updated, and easily accessible!  [View]
