Sections: v0.94 | v0.96 | v0.98

First of all

28.I.2002: Just for everybody who haven't bugged me about this already.

I've temporarily stopped working on Nemesis. The last released version was 0.94, and when the full v1.0 was nearing completion, I noticed the game wasn't entirely the way it should be. I put in way too much features and special stuff (charging bullets for example), and it was just too much for a simple calc. Busy levels ran too slow (like 5 fps) and it wasn't a real arcade anymore. I also was getting bored with it, so I put it on halt and continued working on Wormy. When that's finished I'll try to redo Nemesis a little, and hopefully release a completed version someday. For now, it's just not done; sorry.

Original arcades

All Gradiuses (including the MSX versions I played) are all conversions from these original arcades.

Nemesis title screen; the Gradius version says Gradius Shot of the arcade version in action (looks better than C64/MSX of course) The NES box-cover
The first Nemesis aka Gradius released in 1985. Good versions were made for C64, PCE, NES (see box shot) and of course my MSX.

Konami's Easter Island heads of course also present in G2
1988: Konami made Vulcan Venture, or Gradius II (Gofer's Ambition). Unfortunately ported only to PC-Engine (cover box) and never released in the U.S.

The SNES box
One year later came the third Gradius, which was way too hard in the original. The SNES convertion however was made easier and thus a great game.

A shot of Gradius IV for PS2; looks nice eh?
The latest version was released not too long ago (1998) and named Gradius IV fukkatsu (ressurrection). A title with G3+4 was released for the Playstation2 (looks nice!).

Nemesis for Z80

A cool and fast 2D-shooter based on the classic Nemesis/Gradius. 41 versions made by Konami for nearly every platform, but not yet for the TI-86 (or any calc for that matter). These were the versions I played on my old MSX:

Nemesis II

Nemesis III

I really enjoyed playing those games and since the MSX and TI86 both have the same CPU I thought why not convert it for my calc. Of course it'll never be as good, but I'm just trying to make it good enough compared to other calculator games. The graphics can never be compared to the original or even the GameBoy versions, and also lacks objects and other neat stuff.

Version 0.98

Just the screenies, please...

Dimension TI

DimTI description: A VERY good game where you are a ship and you have to fly around and kill enemie ships. You can choose black on white or white on black. The white on black looks like you're really going through space!

Archive comments:
Mojo Phil: The game is a good idea, but it gets pretty damn boring after a couple plays. Gives **
James Gibson: Fun and exciting. It is great having this caliber. Gives ***** (max.)

Elcobbola's Ti-86 Page

Nemesis 0.94 7/10: Although I'm not fond of this genre, Nemesis is a very well done side-scrolling space shooter. Nemesis has great graphics, speed, and controls. Small annoyances include an incomplete story and infrequent power-ups (a shop perhaps?) but they don't distract much from gameplay.

TI-86 World

Nemesis 0.93 review: 7/10 This is a cool Galaxian type game, but it is a side scroller. There are pick-ups to upgrade your ship, and the graphics are pretty good.


Nemesis v0.90 beta review: 85% A good game, if a bit buggy

Rick's TI-86 Page
