Mmm.. well, with vim on a Linux system. The easiest way to accomplish this, is to first install the oldest player software version you can find. Then remove the hard drive from the empeg and attach it to a Linux box (via a USB dongle, or whatever).

Then, something like this:

mkdir /x
mount /dev/sdb4 /x ## replace sdb with actual device name
cp /x/empeg/bin/player /x/empeg/bin/player.orig
vi /x/empeg/bin/player

## in vim, search for 1998-200 and overtype it with whatever you like.
## Do NOT delete or insert any characters, just overtype them.
## Save the file when finished.

umount /x


Done. Put the drive back into the empeg and see what happens.
