INTRO
This is a 100% English translation of Knight Lore for the
Famicom Disk System. The menu screen and disk loading
messages have been translated, as that is the only Japanese
text in the game.

ROM INFORMATION
This patch will work with the disk file listed in the TOSEC
set. A note on CRC32 values for FDS images: the CRC can be
different on the file you are using because of several
reasons. The disk write date can be different, and the save
game file on the disk can be different. The patch should
still work in this case - usually any problems will become
immediately obvious upon starting the game.

I have included two patches: one for headered FDS files and
one for unheadered files. If you don't know whether your
file has a header, simply make two copies and apply one
patch to each. The file that works correctly when starting
up is the correct one.

This patch is in xdelta format, because it adds data in the
middle of the file, and a regular IPS patch would simply
include everything after that point, rather than just the
part that was changed. You can use Delta Patcher (see below)
to patch your disk image, but you may need to turn off
"checksum validation" if your file has slight differences to
the one originally used for this patch.

TOSEC name: Knight Lore (1986)(Jaleco Ltd.).fds
CRC32: B7D99A11

FINAL THOUGHTS
This was an interesting hack for a couple of reasons. I was
aware of Knight Lore on the ZX Spectrum, and had no idea the
Famicom got a port, although the gameplay is a little
different. It was also interesting from a hacking
perspective: I was new to hacking the FDS, and in ROM
hacking you can't just add data to the middle of a ROM. The
ROM has to be a particular size, and even one extra byte
hits everything out and causes the game to not run.

Because FDS uses disks, there are files which can be any
size you like, and so adding data to them is relatively
easy, once you know how the file system works. So even
though I was only editing the main menu and the disk loading
messages, I still needed a few more bytes here and there,
and was able to just add more data, a much more convenient
solution than the problems you can have with ROMs.

Overall, not a huge project, but a fun one nevertheless. You
should definitely give the game a try, too, it's kind of
fun!

Tools I used for this translation:
