I'm not sure how many (if any) of you know about this but, there
is a way to replace the textures in the PSX version of seemingly unlimited size.
Sort of proof:

Due to the way the plugin renders at higher resolution this actually works! I've also tested it on a few font items and icons. But it works! Not only that it handles layers properly.
There is a rub, the current way is a bit... tedious. To say the least, the output folder is dumping hundreds of small images that need to be assembled then you can replace.
As you no doubt figured out it's a plugin for an Emulator.

The only restriction I can find thus far is the image needs to stick to multiples of the original. As soon as get up from my nap I'm going to try and replace the font! LOL
