Hi,
Is there a way to repair/ phoenix a Black CPS2 (All in One A+B) board? Does anyone have instructions or know someone who can do it near California? I do have rom programmers and extra eproms/eeproms but I belive black boards require something more for SIMM chip that's in it.

I had mine phoenixed by a friend in Cali about two years ago. Unfortunately he tells me the flash chips needed to retrofit the simms are obsolete and unavailable.
 
Thanks for the reply! I'm in southern California, and willing to pay for shipping both ways and pay for his services if he is available, or I do believe I have sufficient tools to achieve Phoenix on the board, only if I can be pointed in the right direction.

Flash chips can be reused... either the ones on the dead board, or ones that are pulled off another board.

I have a few scrap Namco System 11 boards that were donors for flash chips that were used to fix some SPI boards. :)

The hard part is desoldering and resoldering TSSOP package chips. I use hot air to remove them and a hot iron/flux to put them back on.
 
Thanks for info. I do have aoyue rework station, which would help me with TSSOP, is there any documentation on what needs to be programmed? I saw a thread on Neo-Geo about some talks about having instructions, but it seemed to have died without interest.
 
I've never held one in my hands so I can't tell you.

Sorry.
 
The flash chips could not be reused with the method I had originally used which required me replacing the chips altogether. The chips that are physically on the simms are a reverse pinout and neither one of my burners supported them nor did the industrial one at my work place. So no due to the reverse pinout of the chips they were not reusable because nothing outside of programming them on the stick could make that possible.

There are three methods available to reboot these boards. Two of the methods I came up with and are very straight forward. The third method was recently created by someone else with some input from me and is really creative but requires a little more know how than effort compared to my second method.

My first method is as mentioned earlier is to replace the flash chips. This method was the laziest and quickest way I could approach the problem because it only takes me around 35 minutes to desolder and resolder new chips. The flaw of this method is it only works with simm sticks that use the 29f016 flash roms and of course sourcing the replacement roms themselves. Also the soldering required is NOT for medium experienced solderers and definitely not for novice.

The second and superior method is to reprogram not replace the stock flash roms on both types of simm sticks without desoldering the flash roms from the stick. What I did was build a simm to DIP adapter after spending more time than I wanted pinning out ONE of the flash roms on the simm. I half built the adapter and could both read and write to the stock flash rom while it was still on the simm. Unfortunately I did not have the interest to finish the adapter to accommodate the other chip. At the time of this research the 29f016 flash rom was readily available so I decided to scrap the unfinished adapter and just replace the chips all together. Despite me scrapping the adapter it was in SOLID theory a superior method to revive these boards I just was to lazy to finish it.

I will not go into details on the third method created by a long distance friend of mine with some input from me but I will say it is a variation of my second method that requires you to have a certain hardware setup other than a burner which makes it a little more cumbersome than my second method. But the good thing is you do not have to build any type of adapter.


Edit: The replacement chips I have used for EVERY reboot so far are obsolete but they can still be had at LEGACY cost.

Intel and others made Flash ROM chips with opposite pinouts so they could sit next to regular pinout types and allow for higher density layouts on the boards.

I bought a TSSOP to DIP adapter for my programmer to do the regular Flash ROMs and the damn thing arrived with pin 1 in the middle of one side of the chip instead of on the corner. I rewired the thing and it works great for doing the regular pinout Flash like what you'll find on the SPI boards.

All I would need to do is to buy another one of those silly adapters and spend another 2 hours rewiring it to fit those opposite pinned devices. ;)

I could have approached the situation by building a TSSOP to DIP adapter for the inverse pinout but the simm to DIP adapter is a better route for this application due to not having to remove the chips from the stick.
 
Thanks for the reply! I did find the board SIMM has 29f016 flash roms (1 on each side) http://ul.gd/bXoGP , it sounds to me the best way to go about doing this is with custom simm to dip adapter (i do like the idea of not having to remove the TSSOP), or maybe even come up with a reverse, dip to simm adapter. I would be much greatful of any assistance in reviving this board.

seems like other people may have had same questions few years ago. hah i just got intothis hobby and it's looking to be fun learning experience.

I will do more research as needed, but is there a cheatsheet on which flash/dip on the Black board is which rom on a normal CPS2 B board or is it totally different rom sets? Or i was thinking trying to read all the roms from the board and start comparing the bins from what i have on my mame sets. I may be thinking totally wrong as i notice number of chips are totally different compared to B boards.
