Title: Castlevania Bloodlines/Vampire Killer (Genesis) text & graphics editing
Post by: spiffy on November 19, 2017, 09:59:45 pm
I'm currently making a cosmetic hack for Castlevania Bloodlines/Vampire Killer that corrects a few small textual errors, namely reverting 'Elizabeth Bartley' in the intro sequence to 'Elizabeth Bathory (https://en.wikipedia.org/wiki/Elizabeth_B%C3%A1thory)' and 'Alcarde Spear' to 'Alucard Spear (http://castlevania.wikia.com/wiki/Alucard_Spear)' on the player select screen.

So far, I've managed to change 'Bartley' to 'Bathory' in both Bloodlines and Vampire Killer (good thing the latter is entirely in English!), but I can't for the life of me locate the text or graphics data for the player select screen. Apparently, Konami used a unique compression routine for its Genesis games during this period, so I was wondering if anyone who has any experience with said routine or dealing with compressed graphics in general could help me out here?

With help, I may also be able to make optional patches that restores Eric's original feminine features in Bloodlines and/or reverts 'John Morris' to 'Johnny Morris' (https://tcrf.net/Castlevania:_Bloodlines#Characters) for the sake of completeness.

There's a tool which can handle this compression format but I don't know how to find the data offsets.
