    I'm still working on a final release version of my abbuc 2016 game "Space Fortress Omega".

    attachicon.gifSFO wip1.pngattachicon.gifSFO wip2.pngattachicon.gifSFO wip3.png

    I've re-written some routines and used the extra ram to add more features, but there are still a few things I want to improve; I need to make some cuts to some items to free up some more bytes as I'm really scraping the barrel.

     

    Think I'd like to make the ship's movement a bit slower and more tactile but then you might not be able to make it so far across the screen - I don't want to sanitise it too much!

     

    :)

     

    So, any idea of when will it be released?

    Hello everybody,

     

    I'm releasing updated version of Gunfright (version 1.1). This version features:

    - music improved by Emkay

    - loading screen updated by Jose

    - fix for bandit shooting - now, when player moves before bandit, time for shooting the bandit is longer and matches Spectrum version (fix by Lee)

    - fix for original game bug - when unlimited lives cheat was enabled, game panel was corrupted

     

    For instruction from original Spectrum version see here: http://www.worldofspectrum.org/pub/sinclair/games-info/g/Gunfright.pdf. For tips about game strategy see here: http://www.the-tipshop.co.uk/cgi-bin/info.pl?name=Gunfright

    Hotfoot

    interesting because it changes the level data, in a less structured way than Grand Puzzle I.

    So, how to get the corresponding atr files?

    Fellow atarians,

     

    It's proper to start this season with our host´s most recent work: Space Fortress Omega -that has only been available for ABBUC users. :mad:

    That said, we ~must~ demand our good friend Jason to release the game! ;)

    Fellow atarians,


    We've just opened this poll in Atariteca: Vote for what you consider the best port, hack or enhanced/extended game developed this year for Atari 8-bit computers.


    IMPORTANT: This time we are NOT going to take in account "downvotes" against the entries -haters gonna hate...


    So please, feel free to vote for your favorite(s) as many times you want:




    Regards,

    It's rather a terminology issue, so you may ignore my remark about The Monk. But what about other issues - why no tenliners?

     

    From my point of view, it was no fair to make tenliners compete with the other games. Besides that, I did not want to make the list too long.

     

    In any case, I'm pretty sure people can find at least one game to vote for among those more than 20 listed in the poll.

     

    Regards,

    I think the likes of Bosconian deserve to be eligible - though not an original concept it's a ground up production. I'd call it more a clone than a port. To call something a port a significant amount of the assets should be used, and usually a good amount of borrowing or conversion of program code. But in this case I doubt there was any reverse-engineering of program code and even the graphics are sufficiently different to be able to be called original.

     

    Hi,

     

    Bosconian will be featured in the next poll.
