I noticed that Oblige will sometimes crash while generating a Megawad with ObAddon (out of memory, around 2 GB for me).
I know you can patch the exe to become large address but IMO that is only a temporary fix as there's still a limit.
So sometime back in March and after much fiddling in Visual Studio 2017 I managed to compile a x64 EXE from Oblige's v7.7.0 source.
Haven't had any issues compiling multiple Megawads with ObAddon since so I've figured it's time to release this.
Out of memory limit, begone!

Installtion:
Copy Oblige64.exe to your Oblige directory.
Run it!
