This did the trick!
I was finally able to make custom BINs that could be opened with CDmage using this method, thank you so much!
As a quick test, I imported the TITLE.CHR, TITLE.MAP and TITLE.PRG files from Knight's translation over to the Dracula X Ultimate project, and lo and behold...
The SotN title screen from the translation into the Ultimate project.
Albeit, right after I press Start, the game goes to a black screen and doesn't respond after that. (And I think I'm also seeing missing tiles in the background image)
Guess that was kind of expected given how I just replaced those 3 files from the Ultimate project, but at least it's something so far.
I am basically attempting to change Ultimate to just restore the SotN title screen and loading screen, and also change the font to that of the original game. Those are the only changes I want, the PSX dialogue and text I can go without, but those 3 points (SotN title screen/loading screen and font) I'm really aiming for.
