[...] I even changed the name of that fucking annoying back ground that was basically just a glitch
It's not quite that simple.
What I think is happening is that the VNM has a default background (usually just a black screen) that it uses a backdrop to everything else.
... Sometimes... it appears that loading a saved game makes it re-evaluate which default background to use... and rather than use the black one... it uses whatever background it recently used.
So far, I've had at least 3 different backgrounds it's chosen to dump on me.
So renaming that file might solve your immediate issue. But when you replay, it might crash (missing file) or do something else equally moronic. Likewise, you might find it uses a different background to your "fixed" one next time you save and reload that save in the future.
[...] since the dev is unlikely to do anything to fix it, and no one else can, either.
Someone else fixing it within the existing engine is theoretically possible... but highly unlikely.
The VNM's editor is pretty much required to make any significant edits. But as far as I'm aware, the editor won't re-import a deployed game. So without the source files, you're pretty much boned.
VNM stores it's deployed game in a series of JSON tables. Depending on the options you set when deploying it... those JSON files are either stored in plain text or encoded. Editing them
IS possible, but without knowing the consequences of your edits... seriously prone to screwing something up.
Which isn't to say someone couldn't fix it by converting it to a different engine. It'd be a PITA, but you only need search these forums for "RenPy remake" or "RenPy redux" and you'll see that it happens all the time. People rewriting RPGM games into RenPy seems to happen quite a lot. Of course RPGM is much more of a known quantity.
The dev has said he prefers working in VNM than RenPy. Personally, I think he's simplified his game design quite a lot since starting Cuntswell... and I think he's confusing that with VNM being easier. If he'd adopting this simplified approach and stuck with RenPy... I'm almost certain he would have been finding RenPy easier too. But he's got his answer and at this stage, I'm not sure he could be convinced otherwise.
