Pick my diagramm up and enjoy it. :-)
If you have problems with DVD not booting or reading, try the alternative W point.
If you have problems with Reset not working good, try 16 kOhm resistor instead of capacitor or original 33 kOhm resistor.
16 kOhm and the alternative "right" W piont work perfect in my PAL V5.
I used the RCE074 source code from this board here.
Assembled with sasm 1.48.
C:\ sasm /p sx28ac rce074.asm
The resulting hex file was progged into SX28AC DIP version.
fuse=7f2 (code protection= enabled)
fuse=7fa (code protection= disabled)
Code works perfect.
Greetz to all people in the homebrew scene.
