Patching IWADs these days

I just thought I'd give Chocolate Doom a shot, seemed fun. However, it won't run my version of doom.wad which apparently is 1.2. I set about looking for a WAD patcher but Ladopato gives me a "file not found" error when I try to select the WAD file (runtime error 53, possibly Visual Basic related?), an IWAD converter located here doesn't convert pre-1.9 WADs, and the utility that Chocolate Doom points me to (located here) seems to be a 16-bit application I think? Either way it won't run on Windows 10.

Help?

Have you tried with DOSBox? I was able to run the Doomworld patches using that.

Someone has graciously provided me a fresh copy of 1.9 DOOM.WAD, but just out of curiosity, how did you accomplish this? I just gave it a run but I couldn't quite complete the process.

I installed DOSBox to my desktop to avoid user permission problems, then put 12_19drp.exe and doom.wad in the DOSBox directory. I then ran the following commands:

mount D C:\Users\USERNAME\Desktop\DOSBOX~1.74-

D:

12_19DRP.EXE

This gave me the following files:

PSHELL.TXT
PATCH.RTP
PATCH.EXE
PSHELL.EXE
PSHELL.CFG

I then ran:

PATCH.EXE doom.wad

Which gave me the following error:

Could not find the Patch File 'DOOM.RTP'

I then attempted to rename PATCH.RTP to DOOM.RTP, which then told me:

error ept0015: Old File does not exist

Little stumped!

Ladopato is hopelessly outdated, you can use this patcher instead. Should be reasonably straightforward to use I think.

You might need to run PSHELL.exe, can you give that a try?

Gives me a "file not found" error. Not sure what file it's looking for.

EDIT: The patcher @Andromeda linked seems to work just fine so this is no longer an issue, but it's just curious that the utility that Chocolate Doom directly points me to doesn't seem to work as intended.
