Zorba the Geek Posted March 9 Share Posted March 9 (edited) On 09 March 2024 at 2:52 PM, Damnation said: @Zorba the Geek Try Relyze disassembler, or ghidra disassembler, and see if what they output is suitable. Both are free. Ghidra requires 64 bit JAVA 17, and Relyze is overkill for this simple task and probably does not work under XP. I have discovered the disassembler Dibya used for his KernelEx for XP project. The output from the disassembler incorporated into PE Explorer is exactly like the code in Dibya's ExKernel.asm. This is a superb program that enables you to search for the entry point of functions without having to rely on Microsoft symbols which only work on Microsoft products. However, the help file states Quote The generated output can not be recompiled as is and has not been optimized for memory and processor usage so I am not sure that this is the way to go. A MSFN forum member using the name win32 has started a thread titled [WIP] Windows Vista Extended Kernel in which he proposes to develop a kernel extension using the same approach as BlackWingCat which is copy functions as hex and paste them into a hex dump of the section designated for containing these Nt6.1 functions. Judging by this thread this approach is fraught with problems. Quote And yes, the results of most of the posts of mine so far have revealed my incompetence in this arena, which is being corrected as I type.

Dibya Posted March 31 Share Posted March 31 (edited) Use PETOOL by Wildbill to add .exp section before reloc and resource , then move export table into .exp by using PETOOLS, then u can use BWC Pemaker to add your own export. It's funny Zorba figured out i was using PE Explorer for disassembly http://www.pe-explorer.com/ With age i guess i have turned dumb or lazy ( so just use IDA Pro with excellent Hexray decompiler) Edited March 31 by Dibya Link to comment Share on other sites More sharing options...
patchworks Posted April 10 Share Posted April 10 Given that I am NOT a developer (much less a Kernel one), couldn't ReactOS core components be (easily?) "ported" instead of reimplementing everything from scratch? Link to comment Share on other sites More sharing options...

Wine, on the other hand, evolved a lot over the last few years and that's the one having up to Windows 7 compatibility 1 Link to comment Share on other sites More sharing options...

Will have to revisit that project another time because I rely on live DVD sessions because I can't really give up on my XP installations (on both of my desktop computers) at this point. I use live Linux in the same fashion and for the same reason(s). I hope ReactOS will improve their live iso at some point.

I think Skulltrail192's One-Core API (releases), (source) is based on ReactOS. Would call it a 'usable beta,' though it does introduce its own set of issues. Worth checking out though, and irrc the uninstaller works (not a recommendation; try at your own risk). Link to comment Share on other sites More sharing options...
FranceBB Posted April 11 Share Posted April 11 (edited) One Core API is written by Samuel, we know him very well and he has done an amazing job. Please note that Windows XP + One Core API is way closer to Windows 7 level of compatibility than ReactOS will ever be. Also please note that One Core API is largely based on reversing newer Windows functions, so you won't get far here by linking it (probably a mod will remove the link soon as it's not allowed ).

From the README file: "Welcome to One-Core-API! Here you can found source code of One-Core-API project. It is based on ReactOS source and use ReactOS's build environment" Lies? 1 hour ago, FranceBB said: probably a mod will remove the link soon as it's not allowed GitHub [currently owned by Microsoft] links aren't allowed?

FranceBB Posted April 12 Share Posted April 12 It's not a lie, it is based on the original ReactOS implementation and also on Wine D3D for the DirectX10 and 11 implementation, which is totally fine and would be 100% allowed. The problem is that by limiting it to that it wouldn't have achieved much, so it also contains proprietary Microsoft dll which have been patched (hence modified) and backported to allow Windows XP to make use of them by Samuel. He has done an amazing job in doing that and he has been working on this for several years now, however this means that once One Core API is installed, it will replace system libraries and unfortunately MSFN has a longstanding stance against linking modified Microsoft dlls which is why RyanVM was created in the first place. By the way, if you search for posts from 2019 onwards from Dibya, Peter and I you're gonna see that we all know Samuel (heck we were even in the same chat) and we're all great supporters of his work. 1 Link to comment Share on other sites More sharing options...

Yes, I am already aware of One-Core-API, and while it is indeed awesome as mentioned by @FranceBB, I still think it needs more development, because there does still exist some issues, as you said. I am grateful for the fact that it runs very modern programs, but unfortunately, it breaks already working programs that don't need One-Core-API to work, for example, Supermium. I discovered this recently. Yes, the uninstaller works. Edited April 13 by mina7601 Link to comment Share on other sites More sharing options...
