Is it even possible to patch old pc games from late 90's such as Jazz Jackrabbit 3D alpha demo 013D and 013D alpha? I downloaded and patched Unreal Editor 1 for Unreal 1 Gold Edition however is it doable for cancelled demos that were mysteriously leaked online usually by former employees,right? Now everything is now more clear for me that Unreal Editor 2-like level editor for Unreal Engine 1 was related to Unreal Editor 1 all the time speaking of UnrealEdReferenceGuide.pdf.

without source code there is very little you can do to patch the game in a meaningful fashion in the C++ code. unrealscript is doable, but the bugs you describe are within the C++ code, so not so easy i'm afraid.
Where can I find the source code? Do unfinished PC games had source codes or only the finished ones? Guys you have better knowledge of Unreal Engine 1 & 2 than in another different forum related to this game engine forum named Unreal SP.org it seems user JazzGruff/CloverGruff used their advices well it was also wise choice his own choice I don't want to blame him.
ALL GAMES HAVE A SOURCE CODE, THE SOURCE CODE IS ACTUALLY THE GAME.
Jazz has a source code because otherwise it wouldn't exist. However, the code belongs to the company which made the game. Unreal has a source code which is the property of Epic and is graciously given to OldUnreal for maintenance and patching. If you want Jazz's source code, you need to track down the current owner and convince him to open it to the public.

Yeah because Jason Emery the programmer of Jazz Jackrabbit 3 I guess he left Epic Games long time ago I don't know when, but probably when it was cancelled. So will compiling and decompiling be problematic for now?

There's one typo cinvince instead of convince. Will occured poppping up errors like this disappear forever for good if Epic Games CEO's Tim Sweeney decide to give jj3d(.exe file and etc...)open to public? I guess jj3d source code giving it open to public without Epic Games's permission might end up with dmca violations and lawsuits,right? Including money penalties. I'm just wondering where's source code of iios kismet demo tutorial udk/ue3 if iphone exclusive applications got extension file formats such as .ipa in fact this application has no such file as .ipa it's more like pc emulated inside unreal editor(engine)3/unreal development kit. I'm just asking because I want to be focused on jj3d. Can you tell me how to turn 3d maps in jazz jackrabbit 3 into 2d platform sidescroller mode,please?
Is it something related to some missing class in Unreal Editor 1 browse lists?

Is it impossible? I guess it's complicated and highly complexed,right? Well Unreal Tournament 1999 also has no public source code,but at least it's a full game published 21 years ago. Anyway how am I suppose to fix this error of second screenshot because I was testing yesterday NyLeve.unr map file extension format it was working fine speaking of test map however there were no textures(only that ones looking kind of like moon craters)and jazz was unable to swim after testing I closed and I exited the game speaking of jj3d alpha demo this first error popped up(occured) and JJ3DeD.exe unreal editor 1 was closed automatically after that. I made mistake i should record a video yesterday. Are .uc files exportable and importable in Blender not only _d.3d and _a.3d files.

The second error tells you what's the issue: you lack package PlayrShp. This is probably PlayrShp.utx which is the Unreal1 texture package used in Entry.unr (if it's similar to Unreal's Entry). Simply copy the package from Unreal to JJ3D's texture folder and it should be fine.
Yeah because it happened when I copy and paste maps of Unreal 1 to Jazz Jackrabbit 3D. That first error occured before I patched Unreal Gold Editor 1.
This is related to copy and pasting almost all maps from Unreal 1 to Jazz Jackrabbit 3D.

If you want to import full maps into JJ3D, your best bet is to copy the map from Unreal's editor and then paste it into JJ3D's editor. Then you will need to obtain the texture. If JJ3D is able to open Unreal texture packages, then you can simply copy the packages from Unreal's /textures/ folder to JJ3D's (assuming they use the same folder structure).
This will give you a map which looks perfectly similar, but it will lack everything that is Unreal-specific: monsters, maybe some AI actors, items, etc.
