Chris Covell's Creations - Mark II

Even though you can see my older creations back at my other page, I have had no place to put the things that I worked on while in Japan. Unfortunately, in August, my laptop computer's harddrive crashed, so a bunch of my work is gone forever... (;_;)

But anyway, life goes on, and I have been experimenting with programming for other systems. So, I'll present some of my newer works. (Let's hope this small list gets a little bigger!)

PC-Engine / TG-16 Software

Tongueman's Logic is a new PC-Engine/Turbografx-16 game that I'm working on now.

I've just released a demo of the game, so please check out the page I made HERE!

Downland Remake

Click on the image to the left to read more about it.

Fractal Engine

This is a Mandelbrot fractal generator for the PC-Engine. It's certainly not as fast as PC-based fractal programs, but remember that it's running on an 8-bit CPU. It's fun to experiment and play around with.

Now includes a CUE/ISO file for burning to a CD!

BRAM Tool

This is a program for the PC-Engine that lets you view files saved in the backup RAM (BRAM), make backups of the BRAM files, and even edit the data inside BRAM files.

This program is useful for cheating in games, or even just for exploring the save files that your favourite PCE/Turbo games create.

Now includes a CUE/ISO file for burning to a CD!

Split-Resolution Demo

This demo splits up the screen into 3 regions, and shows different resolutions in each region! It looks great on a real PC-Engine system, even though many emulators fail to run it correctly. "Mednafen" runs it quite well.

Click on the images to the left to see what the Split-Res demo looks like on a real PC-Engine.

Now includes a CUE/ISO file for burning to a CD!

SuperGrafx Demo

This is my first (the first?) graphics demo for the NEC SuperGrafx system. I wanted to see what this baby could do, and the result is rather nice. I hope you'll agree with me.

This demo should be run only in a good emulator that supports the SGX hardware. YAME is one example.

Now includes a CUE/ISO file for burning to a CD!

Screen Dimension Test

Don't be scared by all the numbers, but this is a small tool for a real PC-Engine to adjust various screen settings to see what the maximum screen area that can be displayed on your PCE and TV is.

Now includes a CUE/ISO file for burning to a CD!

"Hidden PCE Pics" Demo

This is just a small slideshow that displays some pictures that were hidden away in some PCE CD games.

Greyscale Mode Demo

This is a demo which displays over 100 shades of grey on the PCE, which usually can only show 8.

It only works on a real PCE system, and with some video problems at that. The greyscale mode on the PC-Engine can be called a hack, at best.

Still, smoothly-shaded greyscale pics DO look really nice on my TV. (^_^)v

512-Colour Test Demo

This is just a simple demo that displays all of the 512 available colours of the PC-Engine on a single screen!

"Bomberman" Raster Demos

This is a collection of 6 demos that display a still picture and warp it line-by-line, in the same way as Bomberman on the PC-Engine does at its title screen.

Check them out!

Wavy Graphics Demos

This is a collection of 6 demos that display a still picture and warp and skew the pic in a variety of ways. Some of them are psychedelic; some are relaxing.

Check them out!

High-Resolution Slideshow

This is a little demo for the PC-Engine/Turbografx-16 that uses the PCE's built-in (but little-used) 512x240 pixel resolution to show some neat pictures.

It'll change pics (4 of them) automatically, so just sit back and relax!
The demo was tested on a real PCE system, but if you can't use that, then you'll need to use an emulator that supports the hi-res mode (Magic Engine currently isn't one of them!). I would suggest YAME, or Hu-Go!

"256-Colour" Slideshow

This is a small demo that displays pictures that contain more than the usual 16 colours; in fact, the OutRun pic seen on the left contains 72!

 


Sega Master System/Game Gear Software

 

Game Gear Hicolor Demo

This is my first demo for the Game Gear. It's a small slideshow, and it displays up to 288 colours on-screen at once, something that I don't think has been done before on the GG. It'll look best (?) on a real Game Gear, of course. Download it and enjoy!

 

SMS 3-D Demo

This is my first demo for the Master System. It uses the 3-D glasses to display images in a slideshow, with a 3-dimensional effect!


Game Translations

Head Buster English Translation

Head Buster is a turn-based strategy game for the Game Gear. And it's actually quite fun! Check out my translation effort by clicking on the pics to the left.


Famicom / NES Software

Wide Boy Replacement ROM: Wide Boy 2

This is a replacement ROM for anybody who has the Wide Boy peripheral for the Famicom. Without the peripheral, you can't really get much fun out of the ROM, but there's an example NES file in here for you to play with if you want to.

Features:
* Runs entirely in NES' RAM ($000-$7FF) for hot-swapping
* Allows full adjustment of the palettes for the GB screen
* Has a screen-recolouring function a la Super Game Boy on SNES

Rocky icon by Chris CPro Action Rocky Dec/Encoder
プロアクションロッキーデコーダ/エンコーダ

 

This is a program that decodes and encodes cheat codes for the Japanese "Famicom Pro Action Rocky" device.

Instructions and source code are included.
日本語の指示も含まれています。

Check out my Rocky Page HERE!

FDS Disk Listing Program

This is just a small program that will list the disk contents of any valid FDS disk, giving some information that is stored on the disk. It works best on a real FDS+Famicom system.

Otherwise, you'll need an NES emulator that supports the FDS system!

First FDS Test programs

These are just a couple of small demos that work on the Famicom Disk System.

The first is a player for the music to "Ai Senshi Nicol" on the FDS, but it also provides a visual display of the FDS' WAVE RAM residing at $4040-$407F. If you try this out in an emulator, and you don't see anything moving, then your emulator doesn't support reading from the WAVE RAM, as it is supposed to.

I also converted my "Stars SE" demo to work on the FDS. (Whoopee!)
