Plugins for PSXmemtool:
My test application
for PSXmemtool is quite functional but doesn't do much more than the
bare minimum to run the plugins at the moment:

My first such plugin was Griever loosely based on
things I gleaned from Qhimm who has
an excelent site and great programs. I think he no longer works on them
(not even bug fixes). However his forums are a great resource if
you wonder. The FF8 CRC calculation was snarfed from there.

Jenova
is not identical to Qhimm's work but
similar it uses the CRC calculation for FF7 (differing from that of FF8)
found inside Qhimm's source. This
editor is still under works.

Dagger
FF9 editor still in the works, lots to do yet in this yet. Namely it
needs a complete detailing of the data. Some of it has been found
more to go though.

Serge
is the begining of a Chrono cross is a great sequel to chrono trigger
and radical dreamers (good way to recycle work).

FFO
is well for final fantasy origins (kind of obvious?).
FF4 5 and 6 have yet to be played with but maybe
some day.
