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) ...

I have compiled a (hopefully complete) list of games with speech / samples.

http://www.mushca.com/f/atari/index.php?search=sample

If you use a fairly current browser and have Flash Plugin installed or at least javascript activated, then you are able to use the play button at the respective entry to hear the samples (press play again for next subsong).

So, did you patch the samples in or were they already there but not activated?

I convert the sample data from C64 and integrate it to the A8 version which got no speech until now...

Use an Emulator and change the byte at adress $1935 to #$ad and you got every time you need to finish the game...

I create a version with the speech from C64...

for Lode Runner's Rescue try this version: http://www.mushca.com/f/atari/index.php?idx=L#314|LODE_XE_

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.

I'm not crazy about the altering of the original graphics with the Homesoft graphic.

Just in case you didn't notice it... I removed all the "Homesoft loaders" and all other cracktros too, you wont find none of them at my images anymore...

October 12, 2018

Anyone able to make this into a XEX file for us? It was an updated ROM done a few years ago.

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 ...

September 25, 2017

I changed the content of many images in my collection last time - and still do, it's a process in progress...

There should be only five games left which will need to load data from disk (65,66,68,71,170)...

I'm not sure, if someone is being interested in...

I have finished removing the OS-B requirement of the games around with that "issue" (at least i think so) - see list in post #25.
If i'm wrong let me know...

you can find the fixed ones here: http://www.mushca.com/f/atari/index.php

This version works with PAL and NTSC. I also fixed the problem at PAL in the Title Screen...

I hope someone can convert the working version to an .XEX at some point.

I prefer my favorite games all under MyPicoDOS and this is definitely a favorite.

Oh wow, that's awesome. I would be very interested in knowing what those two bugs were.

thanks...

there was an error while calculating bonus stage (summary.s) above level 12 so the game crashes at level 13...

the other thing i found was, that the warning lights on the right side wont draw correctly from time to time because of a missmatch of the rightblinktimer variable (game.s, needs to be 4 successive bytes)...
