I have been working on may game projects for the Thomson machines but I will post here a couple of those I am more interested in. I hope that posting these will keep me motivated to finish them.

The first project is a game that I am thinking of porting to several other 8 bit machines too but it all started with the TO8 version. I hope this will be my first Amstrad CPC game too.

MO5 and TO7 with colour changes

MO6/TO8:

The second project was an excuse to try to remove colour clash and increase background colour use in Mode0 (native mode of the MO5 and TO7)

This last one uses what I call super colour mode on the MO5 XD

I have coded several sprite engines for mode 0 and mode 3, some take more memory and are fast others are slower but take less memory. I have also coded several tools to help me with gfx etc. My greatest problem will be with sound/music generation...

The first one for the MO5 which is a version of the TO8 game is just a mockup.

Indeed, great job! The games look really colourful and quite fun already just with a screenshot.

Looking forward to seeing more of this.

Supercolor mode is astounding. The work around the color clash using alternate lines produce marvelous results. My eye is totally fooled and do not notice the trick at first sight. Congratulations!

For sound, lets get rid of in-game music and only keep the sound-effects. In that case simple buzzer-effects might be sufficient for a (Thomson) game and will not steal lots of cpu-cycles.

I enjoy new prods for thomson. Keep the good work! :)

Thank you guys.

Before the space invaders game I was playing with the new supercolor mode, unfortunately the background picture is the same:

That SuperColor mode is fascinating. You only need to draw on the "pixel" video-ram to render the sprites. This is faster than modifying forground and background together. This is very clever! Congrats for finding this trick. It is very inspiring.

If you need some other backgrounds, you can try the converter ostro_mo5xd.lua of the enclosed zip. It contains a quick adaptation of my conversion script to the SuperColor mode:
  • Every odd line is white on black
  • Every even line is some fg color on black
So if your sprites are
  • Every odd line "on" pixels appear white
  • Every even line "off" pixels appear as black.

For a first try, it tend to produce some very nice background images compatible with the SuperColor mode. Extra samples are available there: viewtopic.php?f=3&t=383&p=5291#p5291

Very nice pictures.
Thanks for the converter. I can add some superb backgrounds to the game now.

Tah dah another project of mine for the Thomson(To8/Mo6) :)

Smooth multi-directional scroll moving at 1 pixel (or more) at 50hz.
The size of the scroll window is 28 bytes * 128 lines

See video here: pic.twitter.com/uXX4IFLCFy

I am thinking of using this for a game but it will run at 25hz as I need another frame for sprites.

PS: the video runs at a very low rate, on the machine it is completely smooth.

This is pretty impressive. I wouldn't believe it was possible to quickly scroll screen on a per-pixel basis. Well done! :coolfuck:
