Is there a way to modify the game to always load the high resolution textures for the cards?
One way I can think of doing it, is by dumping all the textures through Dolphin, and then replacing the low-res textures with the high-res ones. Although that will require a full dump of all the textures, and alot of manual work.
I did it through Dolphin texture replacement with 2 cards as an example:
I looked into extracting the gamefiles through gctools, and replacing the files that way, but I couldnt get GCTools to work, and i dont know if the game would even load a higher resolution file that way atall (my guess is it wont).
One of my favorite things about card games is the card artwork, and Dolphin can load higher resolution textures just fine as seen in the example. So it would be a nice addition to the PSO EP3 Plus mod.
