Possible Nestopia FDS Emulation Issue
by on (#98023)
The odd thing is that the everything works fine in FCEUX, but Nestopia has an issue.

I have a problem when I expand the files on the 2nd side of the 2nd disk of BodyConQuest I.

Here's a partial file dump. All addresses and the file are are w/o an FDS header:

For some reason it only loads up bytes up to 3ce70, 3ce71, or 3ce72. I can't tell exactly which of these 3 bytes since the last 2
are a line break and a space.

If I make SERI2MSG, KENJ2MSG, or ROUR2MSG 80(hex) bytes longer, then when trying to load RYUO2MSG you get an error 24; it can't
find the header for RYUO2MSG. With the files the size they are, it doesn't error, it just doesn't write over any byte past the
one's I listed above.

I just always seems to not be able to read beyond this byte. It's such a random amount. It doesn't seem to be any power of 2 from
anyhwere.
