Re: Tractor Beam - Galaga style game

That is really cool!!! Can you tell something about the Making-Process?? Greetings Jens Made using Flat Assembler. It's entirely in machine code and even leaves about 1kb spare so memory efficient. As you can probably guess, the aliens are following preset movement tables. Every alien has a home po...

I will make an attempt at a UDG version if you have no objections Bukster?
No objection. I take it UDG requires a modified ram pack and as I don't have one UDG wouldn't work on my hardware. As the aliens are all single letters, it might translate quite well into UDG

Tractor Beam - Galaga style game

Here's my latest game - Tractor Beam. Inspired by the 1981 game Galaga, this game features most of the features found in the arcade game. The aliens can capture one of your fighters using their tractor beam. Shoot the alien that got your fighter when it's attacking, get it back and join two fighters...

Masada Class reissued with 100% machine code

I decompiled my old 1994 game Masada Class and have replaced all the basic routines with machine code. So things like the "one letter appears at a time" style of message writing that I may have thought looked cool back then is now running a lot faster in machine code. I've also updated the special e...

Re: Calvary Class - sequel to Masada Class game

If the ZX81 cannot access memory over 32k, does that mean with 8k taken by the ROM, you've only got 24k to use? Minus screen ram (lo res 792 bytes) and it's closer to 23 kb usable ram. Is that correct? If I'm using hi res the screen is around 6K, so that would be 18kb usable ram It's still a lot mor...

Re: Calvary Class - sequel to Masada Class game

Both Chroma and ZXpand provides at least 32k RAM, so it wouldn’t be bad to use that amount of memory for your great games. True, but I'm trying to write games that will run on original hardware. It's a personal rule, however if I put that to one side, there would be enough memory for powerups, more...

Re: Calvary Class - sequel to Masada Class game

A valid point. I had wanted to add powerups and more stages however, by the time I had the backbone of the game programmed there wasn't much memory left. In hindsight, perhaps I should have done it in lo res.

Still, it could make a good basis for a low res game with more stages and more features.

Calvary Class - sequel to Masada Class game

I've finally finished a Hi Res sequel to my old 1994 game Masada Class. This continues the story which left the heroic Masada damaged in space and spinning out of control after defeating the alien menace. In this game, you are the AI of the newest ship off the line - the Calvary. Travel to the alien...
