John,
When running Val4 in Dosbox, you 'mount' a
folder as a
drive when you load Dosbox. Load Dosbox, then type:
mount C C:\VAL4 (presuming you have Val4 installed in a folder named Val4 on your Drive C, aka C:\VAL4). Presumably you know this already because you can get Val4 to run.
The
above means: inside Dosbox, 'Drive C' actually means: the Val4 folder on your C drive (or C:\VAL4). THUS - since Val4 (or any Sartin program which uses TrackMaster download data) looks for its download files on folder C:\TRKMAST - AND since Dosbox makes the Val4 folder look like Drive C to programs running inside it - THEN, for Val4 to find its TrackMaster files, you must actually place them in a sub-folder of C:\VAL4 named TRKMAST (or -
C:\VAL4\TRKMAST and NOT C:\TRKMAST, which Dosbox does not know about). Then when Val4 looks for TrackMaster files on what it thinks is C:\TRKMAST, it is ACTUALLY looking in the C:\VAL4\TRKMAST folder).
Summary: place your downloaded Trackmaster files in a folder named C:\VAL4\TRKMAST. Use Peteman's instructions above to get your downloads into that folder. Then Val4 running in Dosbox will find them.
(I think I would have written out these instructions in the Notes I provided when I sold you Validator4).
Hope that works (I tried it and it still works for me :-)
Best,
Ted
