Doe anyone know how to program an SP security pic?
I tried the mame dump for tetris Giant on a PIC16F628A with the same settings as the naomi zero pics.
Also tried both the naomi zero pics, none of them work :?:

Depending of your programmer you have to program the PIC then its settings separately.
I had that problem before.
 
@Trol try this config

credits goes to rtw and me

PS: SystemSP are NAOMI1 with integrated "M4-type" ROM board, so it uses security PICs like in these M4 cartridges, and they have NOT the same config bits as DIMM PICs

It's been a while. Also, I don't think I used the TL866 for it. For the record, the config screen on the Minipro is pretty obtuse:

How do the bits correspond to the oscillator settings?
 
Top3000 setting would be fine too, if I can get that POS to work wit a pic chip :)
 
Still not getting anywhere with this board.
It's just sittng at "initializing,please wait" forever.
I noticed this in test mode:Piccy

Is this normal or do I have a broken board?
 
try enabling the pic onboard oscilator - maybe there is no external clock.
 
afaik "FIRMWARE NOT READY" error not related to PIC, if PCB is good and working it will not be shown no matter if PIC populated or not.
 
well, I'll give it a try.... lets see what happens..
Already checked and reprogrammed the Net flash....
 
I am trying to recreate a pic for dinoking 2.5. I have oryginal so I know all is working fine.
Tried the settings from first screenshot with pic16f628a but can not get it working.
I am using tl866. Settings are FOSC1=1, MCLR=1,CPD=1 rest as per screenshot from minipro.
any thoughts?
@MetalliC can you share the config word value?
Thanks
 
try FOSC0 and FOSC1 =1
that will configure for external clock rather than external crystal
