hi all - 
this is the basic solution i came up with to this problem... know my math is wrong but it works enough that i have a place to start fine-tuning:

the timebase is contained in the midi file header. here's a link about how it works: http://www.omega-art.com/midi/mfiles.html
the file header specifies whether the file plays in smtp or midi ppq timing.  you need a hex editor to make changes directly to the midi file.  bytes 13 and 14 contain the timebase or delta timing information. 
here's a screenshot from timepod appears.mid (see below).  The second byte for the SMTP times is the number of subframes.  I don't remember how the math there works and it's hard to track down online.  anyway, the easiest fix I could come up with was to turn off SMTP by entering 00 where E2 is.  that makes byte 2 the number of Pulses Per Quarter-note.  I changed this value to (hex: 30- a decimal value of 48) this was a guesstimate that the PPQs would work if they mirrored what was possible in micro-midi sequencers in video games.  If you do this to all your other midi files, it should work fine. 

@Rocky, 

I have to say, swamptooth raises the bar for jumping in to help someone - in a good way.

I think part of it is that we all have our little pet projects from time to time, and many of us old folks lived through those early years of midi, so when someone says they are struggling with some aspect of working with old game midi files, it just makes us want to give our all to help.

In addition, many many folks have helped me over the years, and the music community is a fairly small one, full of passionate people.  It makes it easy to want to give back, and it is quite enjoyable when the forum can collectively resolve some bizarre issue like the one in this thread.

Wahoo!  (by the way, the pain pills are DEFINITELY working now)

thanks guys for the kind words. bob somewhere along the way i missed you were a coder. we should compare notes.  

hahaha - another big iron guy thats great... i was right around the beginnings of pcs becoming powerful so i went mainframe to client server to migration of mainframe toserver to cloud (which is just another word for mainframe with better graphics). theres something cool about having to write efficient code because your business unit is getting charged  by cpu cycle and storage use. ;)
