Setup board with Fantasy zone romset / PLD's and tested with 8751 bypass
and fire up after general inspection:
Round 2:
Reflowed dry joints and replaced ribbon cables with known good:
Round 3:
CHANGE THE BAD PARTS!!
1x bad z80 (sound)
2x dead lines - 1 shown in video(related with reset) , 1 on graphics ram 6264's data lines.
1x bad rom burn - GFX
9x bad fuji 374's
6x bad fuji 245's
2x bad fuji 377's
And she is working!!
1 minor bad connection on ribbon still need a new connector, otherwise running great!
Now i wait for the sakura roms in the mail, hopefully they are not some convert from later!
If anyone knows any info on sega sakura let me know
