  1. Normally I wouldn't respond to insults...

    @tebe

    I understand how RastaConverter works and my ears are still good enough to hear the difference of sample quality.

    @all other

    Just to explain...
    International Karate was the favorite game in my childhood. My friends and i played it for so many times.
    My motivations were to create a version that integrates the really beautiful new backgrounds to the original code. It wasn't as easy as one would think.
    It is clear to me that more than half of the available CPU time is now used for displaying the background graphic. And yes, something must suffer, in this case the sample quality. But I found that happens in a tolerable way. If you want, you can deactivate the samples with Ctrl+S.
    This version merges the almost 40 year old code with the current possibilities. In my opinion there seems to be no better way to implement the backgrounds without completely reprogramming the game...

  2. Just to explain ...

    Sometimes I create fixed, improved file versions of older games which are not in my collection yet to fill the disk images (for example "Lode Runner" (you can  switch between color and monochrome with console keys, all levels of the original version are integrated in the fileversion).
    Otherwise it would possibly take years until an image is full because unfortunately not so much new games appears ...

    Yes i know, that's why was I asking ... i have checked too many executables these days so I had no energy to check once more since I already found the solution.

    ...however I was curious if the check was completely removed or just inserted required value compared with the checksum.

    I found 3 locations where someting was checked:

    $9847..., $a176..., $a217... - all checks are disabled now...

    It's ok now.

    Could you get the info what did the trick? Maybe $240 ?

    They create a checksum from memory at $501-$5ff (original boot loader) and compare the result with $240. The address pointers are build with indirect addressing and bit operations so there was no direct access to the relevant meory (have a look at $a217) ...

  5. And that includes titles on older disks, there is no changelog other than the "latest updates", so every now and then re-download everything again to get the latest improvements.

    There is a kind of changelog. Enter any year between 2005 to 2019 and you will see the images which was updated in this year. On the fileversion part of the site you will find by "latest updates" the games which dont have a diskimage yet.

  6. The content of my collection is always changing.. I remove the crack texts/intros, fix some bugs, remove the packers, optimize the loading process and make them 'clean' as far as i can... Disks 001- 200 are nearly done...

     

    If i live long enough and have been finished this things, i will put a 'download all' link to my site ;)

     

     

    btw. if you move the mouse cursor over the disk picture on my site, you see the release date of the image ...
