Hello! I have a Toaster NES with a generic famicom adapter and a copy of akumajou densetsu and I would like to mod my NES to play the additional music but I have not been able to find a clear guide anywhere. Does anyone have experience with this mod?
does the polarity of the cap matter?
Wth is that first method? Never seen that before. I am pretty sure most people connect the expansion sound pin inside the expansion port and just wire it to the audio in pin on the expansion pin too? A lot cleaner than the 1st method., you won't have a wire all over your NES.
what i eventually did was solder the 100k ohm resistor and capacitor inside of my adapter and put a wire across pin 3 and 40 of the expansion port, the sound worked great but i managed to ruin my copy of akumajo densetsu somehow. the graphics were all glitched up. i'm still kicking myself...
You can link those pins internally on your NES if you want to not use an adapter and get the sound out of the powerpak if you have one I believe.
i don't have a powerpak, but i do have a T89 adapter. I wonder if i could replace the mask roms with eeproms on my FC castlevania 3...

Instead of modding Akumajou Densetsu (it's a way too expensive game to bother destroying a cart) pick a boxless copy of Madara or Esper Dream2 to mod. PM me if you need any help (and maybe the IPS patch for my Akumajou Densetsu ROM that works on Madara/Esperdream2 board.)
I didn't rout the audio through an expansion port pin because my T89 adapter didn't have the middle pins on the card edge. I had to use a wire. Otherwise I would have routed it through an expansion port pin. I considered purchasing an adapter that did have the middle pins, but I didn't want to spend what they were selling it for at the time when I already had an adapter handy.

I have an T89 too and it actually HAS one of the expansion pins unused.
So I used pin 52 on my T89, which goes to the expansion port too, but does not match the layout used on the Power Pak. I simply added a jumper which connects pin 52 and the pin used by the Power Pak.
