WTB Wanted - Game Boards

Want To Buy
I'm tempted to get an X-men 4 player, but I heard that it has a faulty/shitty sound chip that will need repair. Might jump on it when I get another konami 4 player cab.
Definitely hold off for one that's already been recapped. It's a messy-looking terrible job to do.

@MissionFailed any chance of PM'ing me that thread? I know that the conversions have better audio quality than the original boards, but I've never heard about differences in bullet patterns or anything. I'll have a bit of spare PGM stuff here in a couple weeks and was thinking about doing the DDP:DOJ conversion myself out of curiosity.

Its not that its faulty per-say, but yes it will likely fail at some future point.

Its very hard to repair, so most people simply don't bother...
They will sell the board as "test working with sound issue" or some other such BS.

The issue also effects The Simpsons, because it uses the same sketchy chip.
The solid black chip in the top left hand corner (just under the www.gamesdbase.com text) is the one in question.

I'll have to try to find it. didn't bookmark it and its been about a month. I think they where talking about the Ketsui in particular. would be a hard thing to check for. Would have to memorize the bullet patterns, and or have both copies to compare. i'm going to check YT videos of the games. I can at least say I think the sound on a PMG is awesome.

from another thread :

M6809 (@ 750 kHz), YM2203 (@ 1.5 MHz), MSM5205 (@ 375 kHz)

apparently the M6809 was used in the Simpson arcade. neat
en.wikipedia.org/wiki/Motorola_6809
en.wikipedia.org/wiki/Yamaha_YM2203

TLDR from wiki :

In addition to home computers and game consoles, the 6809 was also utilized in a number of arcade games released during the early to mid-1980s. Williams Electronics was an especially prolific user of the processor, which was deployed in arcade hits such asDefender, Joust, Sinistar, and Robotron: 2084. Williams also utilized the processor in many of its solid-state pinball machines; the 6809 CPU formed the core of the successful Williams Pinball Controller. The KONAMI-1 was a modified 6809 used by Konami in various arcade sets such as The Simpsons.[3]

Robotron: 2084 has some great sound. Love the Gabber genre type the sfx make. i've thought about sampling some audio and playing around with it.

I am surprised someone has not come up with a replacement for this. Is it simply some type of audio circuit on a chip package? I would love to get an schematic of it.
 
Just looking at the explanation made my IQ drop. I'm guessing I won't be fixing one any time soon

If you manage to find a way to do it please share, I would like to do the same as I already have a few PGM spares.

I will certainly do so :).
 
If it doesn't exist we make it ourselves. So, when can we expect a konami multi board?
 
NOOOOOOOOOOOOOOO!OOO!!OOOO
hahahaha....Ok, rephrasing of my comment/intentions. If the audio circuit cant be repaired or repaired in a decent manner, why not make a replica of that audio/chip circuit that is identical to the original and fits/works exactly the same? Minus the black coating, better then throwing the board in the trash. ;)

I love your memes, so here is me trying to have a go at making one.

This is the chip your talking about, correct? Its some sort of capacitor/audio circuit thing on a chip. I am sure an elegant reproduction of it can be made.

There have been a handful of folks on KLOV who have said they were going to take this on over the years. It never seems to get off the ground though.
 
The bottom of it has a custom chip so you would need to be able to steal that chip off the old one to place on any reproduction.
 
better then throwing the board in the trash. :wink:

All the Dreamcast that where thrown in the trash bin because the controller ports stop working....ps1 and ps2 tossed for not reading disc....caps go bad?...throw your genesis in a landfill...

its enough to bring a tear to your eye. Sad face.... bummer electronics are made to be disposable. The majority of users are unaware about console repair. its easier for them to toss it and buy another.

Gamestop and Past FunCoLand are/where responsible for quite a bit of the trashing of retro games/systems. when their finished with a systems inventory in stock they have an employee destroy their games and system stock, so employee's can't resell them and no other local competition can buy them to sell.

They are not warehousing games for 20-30 year speculation as some people might insist. and systems they "try to fix"?? If it can't be easily fixed, they chuck it. their really not repairing anything despite what they might say. not with a repair team of 15 people for the entire country.

Some people call me the video game Nostradamus. and by "Some" i mean "Me" -Heed my warning.. Arg!! Gamer RAGE !I'm important!

7 years from now you will have people throwing internet fits over how bonkers expensive the "Retro" console with spinning media have become. people keep chucking them...And dare I not speak the words that would turn any disc game collector in to a emotional puddle of their former self. (**** ***)

not sure what to say about arcade PCBs without upsetting someone. i'll keep to myself..

few thread i have found. it looks like the cave PGM cart games, other than DDPII bee storm are conversion carts and not official releases. ...poo pooo.

from http://www.world-of-arcades.net/Cave/Ketsui/Ketsui.htm

"It is known that the hardware of Ketsui and other, later CAVE games was made by IGS, and it is no coincidence that it is almost identical to the Poly Game Master system created by the same company. Nevertheless, CAVE released Ketsui, Do Donpachi DAI-OU-JOU and Espgaluda as well protected single board PCBs, instead of PGM cartridges, which had likely been illegally copied by chinese factories soon"

I'm still trying to find the post someone made about the Ketsui PMG cart having less bullets and disappearing bullets. it might have been on Shumps. still looking, but i think it has something to do with "sprite buffer overflow" or a "sprite limit"

I'll report back when i find it. wish i booked marked it. I'm usually better about doing so. ;(
 
So these glitches are only on the PGM conversions or on the original boards, too? It seems that most of the time they were talking about the single pcb versions rather than the conversions but maybe I read that wrong.

I guess it would be interesting to know how the conversions compare to the xbox 360 releases. I was really hoping the Cave STGs ended up on the PGM multicart.

Sorry, I thought that was known. I didn't mean to insinuate that there were any official releases in PGM cart form.

And for the glitches, it's just as possible that it's the source's handiwork rather than the conversion. Hence my wanting to check it out myself. I have a Cyvern conversion from the same source that I picked up non-working for cheap, tore the hot glue off, resoldered everything, at that point it was having weird graphic glitches,
replaced the eproms and now it runs like a champ. I'm a terrible solderer mind you, and my work is better than theirs..
 
054544 Sound Chip Repair links i have found. Google-fu.... Hi-Ya!
Thanks brother, good info.

We used to use a product called Decap from Eastman years ago to remove the epoxy coatings from circuit boards. It was some foul smelling stuff, but it did not damage the circuit boards or components, the best stuff I ever used. However it need to be heated to like 250 Deg F before using it. So you had to be careful. Usually we had to dunk the pcb we wanted to remove the epoxy from for like 1-4hrs at a time. Stuff was crazy expensive too.

No worries. i was editorializing. Never bother to investigate before. I had only read about the PMG carts in passing. I've always favored the dedicated PCBs in my ignorance. have yet to garner any interest in a PGM above DDPII. finding the differences is always interesting stuff.

And for the glitches, it's just as possible that it's the source's handiwork rather than the conversion.
probably has a lot to do with it. If most people are getting them for them same source. why would the guy use hot glue anyway. Gross. and I'm guessing not every cart could be made to same quality.

kinda lame there is "only one" guy doing PGM cart and Naomi cart conversions. apparently charges too much to make it worth it. Selling boots at equivalent pricing to the original is kinda rotten. Though I even consider reproduction MVS carts of new indie games at hundreds of dollars is taking advantage of people nostalgia. but what do i know...

would be cool to see/hear your own conversions when your finished.

Oh, if you have a Kaneko Super Nova, check out "Sengeki Striker" . i've been playing it a bit more MAME recently. Has a lot of exploding debris flying around like Ibara. I like the art design. its good fun, if you haven't check it out yet.
