All,
I thought I would take a look at a couple of PC Engine games that I own to see how difficult it would be to replace some of the Japanese menu text with English. On the first game that I looked at, I was able to locate a string and successfully change one Japanese character to another. However, when I load up the ROM into a tile editor, I do not see the font. As a result, I am assuming that the font is in some form of compressed format, based upon some of the articles I have read on this site.
Does anyone have any tips for me in how to get started with locating the compressed font? My first inclination is to use a debugger (I have Mednafen) to try to track down where the font graphics are getting pulled from when they are loaded into memory.
I did a little bit of Intel assembly back in college, but it has been a good while ago, and I don't have any familiarity with the PC Engine assembly instructions. Any recommendations on good docs covering the assembly instructions for this platform would also be appreciated.
Also, what tile editor would you recommend for PC Engine ROMs? I have been using Tile Molester up to this point.
Thanks,
Fabio
