Greetings, I am trying to get the sound effects tracks off the Akumajou Densetsu NSF, but am having some issues. The NSF started with 28 tracks, so I first I changed byte 006 to FF (as suggested in this thread viewtopic.php?t=8114). At this point, I can hear the sound effects in the additional tracks, but track 17 plays as well for every track past 28. This is preventing me from getting the sound effects:(

This is what appears to be the track replacement code:
0A:E0F1:AA TAX
0A:E0F2:BD 00 E1 LDA $E100,X @ $E100 = #$51

When I set this code to EA EA EA EA, it simply plays track 17 for all 255 tracks. Any ideas, thanks!

I just changed the number of tracks to 255, then changed the 3 bytes at A17A in the file (actual memory address = E0FA) to EA EA EA, then it worked perfectly.
Sound effects come before the songs, songs start at 81.

Edit: My post was for a DIFFERENT version of the NSF file, named "AKUDEN.NSF", not the one attached. It has an init address of E0F0 instead of E0E0, and different code there. I just tried the hack for the NSF you posted, and it ends up playing each sound effect over the end boss theme for every track.
I've posted the successful hacked version here.
