For about 3 years or more most people say that NSF2midi and SPC2MIDI has a very bad and serious problem with generating decent workable midi's.
I looked at your forums last year quite a bit and noticed that most of you don't approve of or use converted music because the exported file came out unreadbable to most midi editors and camed out damaged.
I have been working on a solution to this problem and I have come up with a full proof soltuion to fix up those messed up midi's and just maybe if a administrator see's this and test out my theory that they would approve some converted music if the user how does everything I said to fix the midi.
I really do love to work with music especially midi's that come from different sources.
Usually I remix some of the midi's found here but don't submit them because I keep it to myself and don't want to a war on a board over something innocent that I "THOUGT" I was doing.
Here are my directions:
1.Open spc2midi, then open a ripped spc either from www.zophar.net
or the zsnes emulator.
2.Readjust all the instruments if you can spc2midi and click save.
3.Open the "UNREADABLE" midi in Music studio Producer FULL EDITION. http://www.frieve.com/english/musicstd/musicstd.html
4.Choose export the file as: MIDI standard version 1.
5.It will save the midi and fix any problems with it.
test this out in other midi editing suites such as sonar to make sure other programs can finally open it.
6. -FINAL RESULT-
Now as far as I can tell you if you follow this procedure sonar 4,6,7 and 8.2 can up your midi's when you edit the midi in sonar it will recalibrate the midi with it's patch and adjustments and you will have a new midi ready to submit.
