"From I bought SC126 mother board from tindie Steve Cousin-san in last November, I'm gradually stoked with RC2014 world.
I made SC126 Z180 mother board, SC129 degital IO board, Compact Flash Card Board, TL311 Bus monitor
Dr.Scott-san Board, and Step Executor also Dr.Scott refering board. This time I'd like to add Sound Card with my RC2014 rigs.
But this project was confronted many obstacles regarding SC126 and Sound card matching. Then I'd like to explain how to play PS3 music through tune.com produced by Wayne Warthen-san who is developer of great RomWBW.
STEPS to play music SC126 and sound card.
1, I downloaded latest RomWBW pacage shown below.
https://github.com/wwarthen/RomWBW/releases
RomWBW-2.9.2-pre.22-Package.zip
2, Remove SD memory for SC126 and attach to your PC and format it.
Then write hd0.img in RomWBW/bin folder utlizing Win32DiskImager.
(Which contains in RomWBW/tools folder also.)
3, Attach the SD memory again to your SC126 SD card reader and reboot.
Change dir to G:user 3.
Check Dir and it shows tunes.com and many pt3 music files.
4, Try tune action.pt3 but oops! sound card didn't recognized.
5, I have changed YM2149 sound board IO base address default $D0 to $60 for SC126 mother board to avoid
address confliction.
SETTING: JP1:2-3 ⇒1-2, JP7:1-2 ⇒2-3, (CS=A4"L") JP4:7-8⇒13-14(A5,A6="H",A7="L")
Do you understand what I mean ?"
