DAYTONA 2 arcade model 3 GAL16V8D DEFECTED IC

[jugurthabrasil]

Hi everybody

i don't know if i am in the right forum ..but who knows

well i have a big problem with my daytona 2 arcade , model 3
my game board don't boot anymore ..seems to be the GAL 16V8D15LP ref 315-6090B
i pull off from the other daytona twin this GAL and pull on my not working daytona and it works ..then must be this STUPID GAL the problem
ken told me , Sega no longer sells them either ,
perhaps on this forum someone have this part for sell ( need 2 or more in fact)or some information for find a solution
andy seems to be able to help me perhaps too

anyway thanks for all if you have some idea , how to resolve this problem

If the GAL is not protected then it could be read and duplicated. Unfortunately, almost all of them have the protection bit set.

I'm sure this one is set as if it wasn't then Ken would've been able to duplicate it.

 

[mainman]

I'm not trying to depress you but you can be guaranteed sega set the protection bit on that gal why it was programmed. Basically you would have to acquire another possibly junk daytona board or write your own truth table for another gal and it not fun at all I can tell you the glitches I went through when I wrote one for the G pal for cps 2


Sega no longer sells them, damn idiots I heard rumors those fools are notorious for losing/destroying code for their arcade games because thats all you need is code, plain software as the physical chips are generic and easy to come by.

 

[channelmaniac]

Yup!

That's the benefit of using programmable logic: you can set a security bit and it helps to keep the hardware from being bootlegged.

There are ways to reverse engineer a PAL/PALCE/GAL chip but it's not for the faint of heart. I've never tried and don't have the equipment to do it.

You could probably send it off to a company to decap the chip and read the data with an electron microscope. But we're talking thousands of dollars to do that. I think it would be cheaper to get a new board...

thanks for all guys

well not good for my heart to listen that , expecially with a so expensive price for a daytona 2 .....around 400$ on ebay i saw one some weeks ago

may i call to SEGA in japan and ask them if they can find out for me some GAL ?;-0
or if i must burn my daytona and keep only the other ...

i saw on my spike out i have too have, the same GAL with the same reference ..i am so afraid something wrong happen and burn my SPIKE OUT GAL ....
but perhaps can me easier to find from SPIKE OUT ( i saw some on coinopexpress with TBA PRICE ...)

well i am not a specialist but i bought from JAMECO some GAL16V8D15LP ..i thing they are empty , perhaps i could write the jed i have and the jed andyweezer send me ( thanks so much to him too )
anyway if some solutions or tips ..iam here


by the way channelmaniac ..i have around 10 neo geo with problem ...you will do a good price for repair them ???
i saw on you message about insurance for shipping and you didn't undestand why some don't want insurance for shipping
well for exemple here in Brazil ..i never ask insurance cause if you do a custom declaration with insurance ..you will pay custom brazilian tax on this price ...100% custom tax ...then better to risk than to pay a so stupid custom price


see ya

Good luck trying to negotiate with sega of japan as they will not deal with anyone other than JAPANESE distributors, but if you can get your foot through the door sega japan is capable not like their global sub division retard counterparts.

I could not understand your spikeout question there a language barrier.


If the file andyweezer sent you works your good to go, do you have a gal on hand to try it out

 

[doggydodomi]

How about this guy?

If Andy gave you the .jed file I can program that into a GAL chip for you.

I believe I have a handful of new GAL chips in the shop... It would be $3.99 for the GAL, $11.95 shipping (USPS Priority Mail International Flat Rate) and $3.99 for a programming fee.

Hi RJ

Like i wrote yesterday , i bought from JAMECO some GAL ...i think they are empty..i think ...not sure , for try to write the jed program with my EEPROM writer ..i will try to resolve the problem by myself first ..and if i can't i will contact you
i already try to write this GAL to another empty GAL ..and that didn't work .., when i tested on my writer eeprom all was on the GAL ..after i pull on my daytona , same problem happened ....no boot a all .perhaps with the jed i received from andrew it will work ..just need to wait the empty GAL ...

see ya

yes it's ken site , i talked to him and gave me andrew email about cause he doesn't have this GAL for sell and he told me andrew can help me better about this defect

see ya

i explain better
on my spike out i have the same GAL with the same reference ..exactly the same reference , that mean for me ...same program on it , then like i explained , i could try to pull off from my Spike out this GAL and pull on the DAYTONA 2 ..,i did that and 1 burnt so i don't want for the second spike out cause if something wrong happen then i will have 2 out of order machins ..and theses machins like you know are playing so much ..

i still waiting to receive the GAL from jAMECO already

sorry about barrier language ...better for me to talk in French or portugues than in English , sometimes it's difficil really ..

thanks

The only was it could have burnt is if it was put in backwards as gal much like most standard logic have vcc and ground in the same place. Don't risk your other spike out though.

Sometimes but very rarely different games will use the same truth table for their pals but that half defeat the purpose for the pal.

Hi

itryed to write with my EEPROM writer this GAL again but with the jed file from andrew ..i have the same problem and i have the led14 and led13 flashing all the time.
theses led 14 and led13 it's diagnostic i think but for what ?
someone have explication of each led ?

the GAL can be write and erase 1 time? or can be erase and write often ?

thanks

The gaal is rewritable like a eprom, there something wrong with jed

 

[jugurthabrasil]

hi mainman

Something wrong with my jed ? i have 2 jed in my hand ..andrew jed and mine i saved , and when i tryed to write they gave me the same error ..led 14-led13 blanking
i am thinking it can be the GAL i have ...perhaps this is the problem , for that i am waiting m news GAL i bought some days ago for be sure too.

after that if i don't find a solution ..i will go to church for ask god help me to find a solution ...cause i have my limit and i can't ask help everytimes too ...

see you

 

[channelmaniac]

Did you receive the new GAL chips from Jameco or are you trying to reuse the old one? If the old one is bad then reprogramming it won't help you.

If your trying to reprogram the original gal on your daytona its futile as its bad, thats what started this.

Make sure the the new gal you have is the one you need and make sure you have the right chip selected in the programmer id.

hi channelmaniac

I still waiting theses GAL from USA ..here not easy to find then i try to buy all in USA

i was thinking the same about the old GAL i have , it's for that i waiting to receive new empty GAL for make a real test


anyway thanks so much

oh yes i will do that , i chose the GAL 16v8d on my programmer too , but not working ..it's for that i am waiting the new GAL , for be sure and test in the right way

thanks so much anyway
