Here is a Ghosts N`Goblins PCB by Capcom that has missing suddenly rolling background sprites that seem to be cut. There are also flashing vertical lines in the background.
Sounds like some great memories! wish the arcades at the pizzerias made a comeback again! I guess that since it hardly takes no time at all to make them now, it might be pointless but hey, one can dream.
Always have loved Ghosts 'N Goblins probably since I first encountered it at our local movie theater around 1985-1986 in my early to mid teens. On my 15th birthday in December of '86, I bought it for the NES with birthday money along with The Legend of Kage at the mall. I surprised my friend Rodney when I completed the NES version twice (as required to get the true ending), especially since there is no save option or code (although there are limitless continues). Great job getting this back up and running man!
What a story Tman! really impressive about the double run by the way! Glad to have saved this one and will try to put up a vid on it soon. It sure wont be a double loop though lol! Hope you are doing well!
Amazing job as always finding and repairing the problem, I have a bootleg of this board and it has an issue where it just freezes. You have inspired me to try and navigate through a possible fix. Thanks again for the great videos!
Thanks a lot Scott! Give it a shot and see what you can find. It may be a bad connection issue as well. Check the ribbon cable connectors and check the soldering points on the bottom of them. They may be cracked. if so, use some flux and solder and add some fresh solder. Hope you can figure it out!
@@lukemorse1 kneel down and shoot one of the first lot of grave stones several times. It's one of the first 3. I think it's the 2nd or 3rd one. Keep hitting it and after 7-8 times and you get turned into a frog. Give it a go.
Well done, Luke. These masked boards are a pita. Also, the finger probe is an underrated and overlooked piece of test equipment. You'll be surprised at how many faults I've found using the finger probe.
Thank you so much monstermug! I couldnt agree more! the human body can be a great tool in itself for checking these boards, as long as you dont use the wrong parts lol.
Hey there man, always good to hear from you. Glad to have another board going and looking forward to making a vid on some game play soon. Take care man and thanks again
It lives again! Thanks man! That sounds like a pretty awesome memory for sure. The idea of a seaside arcade seems cool 😎👍 Thanks for the story and checking in as usual! Hope your gaming streams continue to go smoothly and do well!!
Thanks a million my friend! RIGHT!! ? at the end there, that was so unfair lol. Made me second guess if repairing it was the right decision or not lol 😂 😁
Somthing funky is going on here kids...let me whip out my test light an start the magic. Would be a labor of love to map the board via by via. Almost like rebuilding a skyline from frame. Eating a pizza...sitting back waiting for the connection to found an de duced...only a matter of time for the Lukester to sniff it out. An dont think I would not of enjoyed the whole search mission. 😉🍻 alwAys amazed at the skill . Enjoy the weekend Brother God bless
Kevin my man, you are a true gem! thanks as always brother for the positivity and good vibes, I really appreciate it! Glad you came along for the ride on this one and Ill see what else we can come across here in the future! Hope you also have an amazing weekend!!
I can totally relate to that. I was having such a "fun" time even with the schematics trying to find out what was up with it. Not fun at all. The missing sprites with yours might have been tied to those IC's on the back but I realize its a little too late now. Maybe this vid will come in handy for the future though? one can only hope.
You know it! Lol, sometimes works better than the test light lol. Btw, I think I need to order another Capcom adapter from you in the future. Too many boards and would be nice to have an extra one 😊
Bonjour Luke ! I don't understand anything, but it's so interesting to see you fixing these PCBs. I wouldn't be able to do it, moreover a Capcom that I particularly like. Bravo et merci Luke, encore une belle vidéo ! ;)
Bonjor Retro gaming a papa!! Thank you as always! I'm sure if you tried something simple first, you would get better and eventually be able to do it yourself as well!! Thanks for dropping by again. Merci boku!!
Thank you so much! To be honest, its a learning process for me as well as I go along. Figuring out what might be wrong and ruling out what isnt the problem. Still a long way to go.
Doctor Lukemorse1 does it again 👍 Another classic Arcade PCB nursed back to health 💪😎 It's a shame though that this board wasn't one of those boards that were full of nasty creepy crawlies as it was so much fun listening to Luke describe how those nasty stuff smelled 😊
Haha! Sometimes NOT having the bugs on the board is a plus :) glad I was able to get this one back to fully working again though. Another one saved from the grave! Thanks Cahos
@@lukemorse1 No No My brother you cant thank me i should thank you :)i dont miss any of your( GOLD) vidoes ! Me and my few friends here (jordan-amman) we stuck like you in GOLDEN time 80s and 90s :( keep going you have all the support from us :) Wiw
A bit excessive but honestly, if the schematics werent available for Ghosts n' Goblins, people still wouldnt know know to repair other Capcom pcb's like this as there are no schematics for them. Several people keep going back to the GnG manual to figure out games like Legendary Wings, Black Dragon, etc.
Thanks Ninja Master! I try with these things as much as possible but you are right about the TTL's for sure. I was really hoping I had it early on as well but what can you do eh? At least it is running again and I plan on taking out some of those other Fujitsu's here soon so I wont have to worry about them in the future.
My double axle when it loads the taito symbol is scrambled thwn the title screen is scrambled. Then just some of the background is scrambled. I dont know which chip to check
Luke, I have a bootleg version of this board and I had a sprite glitches. It was some one of the 7400 chips. GnG has so many logic chips on it! Painful to work on!
Does the piggy back test method only work on ram chips? I could possibly have a bad Yamaha YM3014B. If I piggy back with a good one in theory it should work or start seeing smoke and kill the board? Your thoughts.
Great question man. The answer is yes and no. The piggyback method will work with many ICs but there are some ICs that have a clock circuit or may go bad if jumped with even a similar IC. For sound chips, ram, gates, etc, you can usually try that method. Even with maskroms you can piggyback an EPROM (as long as it is the same). With the sound sections of boards, the Yamaha ICs have a tendency to go bad often as well as the amp attached to heat sinks or bad capacitors, ram etc. First, Try the piggyback with the ram and YM amps and see if that changes. If you get sound, you are golden 😁
@@lukemorse1 Well sort of worked. Anytime touching the chip the static would disappear. Replaced both YM3014B chips. No more static on boot up. Fixed that. As for the SFX still sounds muffled which could be a bad ram chip. I more or less know where it is. Speech and music is fine. BTW this is a Robocop Version 1. Rom board is fine CPU board is what I'm working on. I've already replaced 2 bad ram chips tc5565 just to get it running. As usual thanx for the inspiration... What you do is an art form...
Bro do you have a method to get in contact with? I have a question or to see if you can help me with a situation. I recently purchased a naomi sun power supply off ebay and it was listed as not tested. I swapped out the major caps and it worked for a few I plugged it in twice 2x just to make sure it was okay but the minute I placed it back into the chassis it stopped working :( idk if maybe it came in contact with some metal and cause some points to short or what but I wanted to see if maybe you can take a look at it or help me.
Great repair, I've a Popeye single board bootleg with graphic problems like the Popeye after booting is incomplete an the sprites ingame are incomplete. I read that the RAMs 2114 could be the problem. What's your opinion?
Good question. There are a few reasons for this. 1st is that if the board had a problem with this IC before, there is a chance it could have the same problem in the future so it makes it easy to replace. 2nd, If the replaced IC isnt up to spec, is damaged, or is a fake IC (that happens from time to time), it would mean that the IC would have to be removed again. Sockets make the swap out process easier. 3rd as a rule of thumb, when replacing IC's it is always better to socket them because when you remove an IC you add heat to the board as well as the via's which weakens them each time you heat them up. In some cases, you can wind up ripping out a via, losing the pad to solder to, or rip a trace which you will have to patch and repair. Essentially, putting in a socket prevents further damage to the board in the future and allows for easier repair/trouble shooting in the future. So many reasons to add sockets, (obviously a whole board with sockets is quite rare) but usually these are some reasons why :)
@@lukemorse1 Wow great answer Luke! Thank you! I have in the junk pile a Centipede board that has no less than 30!! rusty, corroded chips that need replaced. I went ahead and found and ordered all that are bad. I thought it would be a good board for me to learn on. (board is bad but maybe salvageable) I'll end up spending way more on it than what its worth but what the hell?!? I thought of just soldering the chips right back on but your ideas make much more sense. Now I need to get some sockets as well... You vids have inspired me to try! Please keep them coming!
Good question. The IC's that I replaced in this video are all drop in replacements and no programming is done. When you start talking about a PROM or EPROM you will need to have a programmer handy for those. Not all programmers can program PROMS though and the replacements are sometimes not available. As a rule of thumb, just make sure not to damage those. You can check what it is by entering the part number into google.
LUKE MORSE, when having graphic issues I have seen other repair tech take the logic probe and short bridge two data lines on the IC chip going down the chips pins one by one shorting bridge them using a logic probe and watching the display to see if the graphics get worse. I'm not sure what the technique is called try to find out the name but if the graphics get worse then they know which IC chip is bad. Try it out in your new troubleshooting videos
