The loderunner engine was, iirc, compiled as a ZShell 3.0 string,
and thus not showing up in the ZShell menu. In most Usgard shells
however (note, it's the shell that shows the program, not the
Usgard core) all strings with an ID byte >=$F8 (the current Usgard
version header byte) are shown. I guess ZShell 3.0 strings had
the header $FE (seems logical since 4.0 has header $FD).
If you want to make your strings not showing up in the list, choose
a different header when running string85.exe. There is list
in the Usgard ZIP (filehead.txt) which lists all headers
currently used by different programs:
LIST OF FILE HEADERS:
~~~~~~~~~~~~~~~~~~~~~
00 FD - ZShell programs
00 F8 - Usgard 1.5 programs
00 7D - 128 x 64 B/W image
<cut>
PROGRAMS:
~~~~~~~~~
(first byte=game,second byte could be [save game,level,hiscore,...]
01 00 - Plainjump II level file
02 00 - Sqrxz world (not compressed)
02 01 - Sqrxz compressed world
03 00 - Plainjump level file
04 00 - Balloon compressed level file
