What's new
Wow! I paid what I thought was a lot for my conversion... I guess COVID job loss hasn't hit obscure arcade collectors!

I like the game a lot, but I think I'm actually leaning toward actual Strider 2 a bit more, even with the stupid polygon graphics!
 
@twistedsymphony sir ive done Charlie Ninja conversion few hours ago since the Chain Reaction pcb had all sockets installed , but i dont hear the vocal samples when you hit the enemies... in rest , image and speed background sounds are present normaly . Where to recheck again to have that vocal samples too ? Thank you for all ✌️

Ps : should i rewrite again 12f & 13h on others 800’s ?

verifying the audio EPROMs would be my first step check the speed too.
27c800 are “-100F1” ones , the 4002 one is -12f1

@twistedsymphony .. sir, the main cpu eeprom has to do something with sample sounds ?

This video is done before speed mod. After the speed mod , all good with that sound tracks

try a 100ns chip replacement
I put a -10f1 and didnt change something ... remain that 800 to rewrite again maybe from there is the problem . I suspect 13h who keeps the okisfx file must be replaced . I powered the board without 12f inserted (oki music file) and is no sound at all with perfect image and movements . Without 13h inserted not perfect image but sounds like before without that samples when you hit enemies

@twistedsymphony sir , I replaced 13h & 12f too on a NOS 27c800 and still no that vocal voices samples

your wire mod looks correct but are you sure you fully cut the trace? have you checked for accidental bridged pins?

I cut only on pin 5 . To be sure i didnt cut other connection i put multimeter to be sure its not nothing lost near and all good sir
Actually , the traces on the component side are realy solid . On the solder side the cut was much light to cut in comparation with what i did on the componeny side

Cannon Dancer is now running on my Data East board

Thank you very much @TheDeath & @twistedsymphony for your awesome lessons ✌️!!!

Ps : this is the same hardware where previously tried to put Charlie Ninja, but on Charlie i dont hear the samples sounds when you put credit ,when you are hit and when you hit enemies (okisfx) ^^

Hello.

What mistake did I make?

And... How can I fix this problem?

I pushed test switch on during booting... but nothing changed.

Can somebody help me? :)

I think I have something to do to join there. :)

Pictures as I attached, problems left.

Actually I don't know that I cut the trace right. I cut printed pattern of pcb near 13A, 14A 32 pin.


And wire 11A 9PIN to 13A 14A 32PIN,
11A 8PIN to 13A 30PIN.

Please let me know
Where to cut! And I did right or not.

Thanks!
Cut the traces (on the back of pcb - solder side) to Pin 32 on the EEPROM sockets at 13A and 14A, wire these together then Wire them to Pin 9 of the 74LS373 at11A
Run another wire from Pin 8
of the 72LS373 at 11A to Pin 30 of the EEPROM at 13A

You are very close sir ✌🏻

ps : solder of you wires seems to be good

Thanks a lot!

Finally I made it :)


PS.
When I desolder 13A IC, Maybe I cut a pattern of pcb, so 13A socket didn't work well.
I repaired it, and it works well. :)
