EddyFree Posted July 16, 2020 Author Share Posted July 16, 2020 (edited) For those who aren't sure how to apply/use these cheat patches, I'll give two examples. First, for the "permanent change" applied to the game file, use a "Hex Editor" on the PC/MAC that supports search/find. One supporting wildcards in the search is a plus. Select to search and key in the first set of hex digits(before the colon). Once the editor finds the series, simply change the series to those hex bytes in the second set of hex digits(after the colon). If the bytes are labeled XX ignore/skip them. Then save the now-patched game file. If the editor fails to find the series, you are using a different version of the file I used to make the patch(ie:compressed version), try a different version. As for doing this on actual Atari hardware, I'm not aware of any hex editors that offer this feature. There are several "sector/disk editors" but you would need to make sure the found series resides in a sector that belongs to the particular file before changing it. Maybe someone here knows of a native Atari 8Bit Hex editor that does search/replace on files? Some examples: Robotron 2084: ------------- Infinite Lives = [CE8F0A:EAEAEA] Snapshots Of Patching Robotron 2084 Game File (My Choice Of PC Hex Editor Here Is The XVI32 Editor): Found, and then replaced: The second approach is to use an emulator to make the changes in the emulated memory AFTER loading the game. Although the patches were designed for files, many can be applied directly to memory in an emulator. Of course, this is temporary as the memory isn't saved to file but it's still an option. For example, in the Altirra emulator, you can load the game, drop into the "debugger", search for the bytes in the search series, note the address they were found at, and then "edit" the bytes at that address to be those in the replace series. Exit the debugger and the patch should be in effect. Keep in mind that sometimes more than one occurrence may be found, in that case try them one at a time until it works. If the search series isn't found, then try a different version of the game file or it has obfuscated code segments.

+CharlieChaplin Posted July 16, 2020 Share Posted July 16, 2020 There are dozens (if not hundreds) of disk/sector editors on the A8 which can do this, as long as they support HEX editing, which most do. I am using Happy Master and Hypra Disk quite often, they both have a search option... Happy Master Quad+ Hypra Disk 1.3 (Happy Master: Press HELP or Control-H or just H for the help menu; Hypra Disk: Press Control-I for more info) 3 Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted July 22, 2020 Share Posted July 22, 2020 Hey EF, excellent work and dedication, going through the XOR'ed stuff is above the call of duty, I remember sitting with the wonderful Diskey by Sparky Starks hunting out hidden text using the same method. You would start to see obvious patterns in the sectors. Doing the same for code is excellent. 5 Quote Link to comment Share on other sites More sharing options...

Frogger was a tough one, even had checksums in it. But I guess the more challenging, the more rewarding it is when you finally figure it out. 3 Quote Link to comment Share on other sites More sharing options...

It is indeed, when they started to protect against Omnimon with very very simple checks at $C000 you started to see mem wipes if it was installed. so you had to start getting rid of those before the real work started Wow, code base checksums, thankfully I never from memory had one of those.....Clever way to check tho, even more clever to see it happening and remove it The power is strong in you Jedi As always, thank you for your great work..
