Re: Good to be here!

zxooner, great that you joined this forum. If you want to make a step forward from Basic but ASM is too difficult for you (as it is for me), then you could try developing in C using z88dk.

z88dk: Creating flicker-free animation on the ZX80

ZX80 flickerfree in C is possible in very simple games that loop over the same instructions all the time. Thanks for your explanation, now I finally understand why DStar has smooth flicker-free animation and why I couldn't make it: in my game there are just too many other things going on inside the...

Re: CROSS CHASE

A great little game, and your target list is very impressive! I have to admit that I learned a few things from your source when I started porting my game H-Tron to other Z80-based machines. In the meantime, z88dk has improved a lot, for example new targets have been added. I noticed that the followi...

Re: "Patrulha Espacial" Patch for 50Hz ZX81

When I tried "Patrulha Espacial" and "Missão Andrômeda" I was surprised to hear my Chroma Interface-equipped ZX81 play music over the TV! I don't have any sound equipment, so that was like when your cat suddenly starts talking to you... Activate "Beeper Sound" in the EightyOne emulator, then you wil...

Re: Work in progress : 1K hires Stupid Cupid

The hearts will then drop from second line down and on top moving horizontally. I think it would be better if you would make the vertical ones pause for some time to allow the player to catch his breath again. This would be some sort of a bonus round where the player can score extra points but cann...

So what can be added in the remaining 352 bytes?
Nice game! The shooting is a little monotonous, maybe you could add a horizontally flying heart that sometimes appears on the top of the screen (instead of the falling hearts), just like the saucer in Space Invaders?

Re: New game - BiggOil

I was thinking about trying to write an "Anteater" game, but I'm glad that you did it first. All those little details - the oil company idea, the "panic pipe retreat", the rotating hose drum, the moving clouds - make it a very enjoyable game! And it's very addictive, because the bottom cave is so ha...

Re: LODERUNNER on the ZX81

Hmm, looking at the Loderunner screenshots at Mobygames I see that the original Apple II version had blue bricks, while the PC CGA Version had cyan bricks...

I prefer your blue brick version, but that's of course personal taste. :)
