DARKSOFT New Namco System 2 Multi

[Darksoft]

@Darksoft … big thanks . the Namco System 2 multi is perfect working . Not any issues here , is super easy to install the kit (i did it hy looking in your almost perfect instruction manual installation notes) , perfect fit in sockets on both boards . Also is lovely to use Proman

Only when update the manual , on my donor (on motherboard) , on the back of 2E logic ic (HD74LS244P), we have JP18 - is set on GND not on VCC . ive seen this mentioned by @Mrhide too . I did namco sys 2 conversions on both motherboards models and i forgot mine had this jumper

well, that's interesting. My 2x PCBs don't have that JP18 pin at all. You can see the picture in the instructions or here:

Well, my graphical issue was a dumb oversight. Somehow I had JP7 and JP8 reversed, even though I double checked before main assembly. I really need to stop trying to do projects after 13 hour shifts.

Everything seems to be working 100% now. The only issue I see is on the english translated rom Valkyrie, where there's some small artifacts above the character sprite.

Here is an explanation.

Like others stated there are two versions of the CPU board: one has a custom 65 which may or may not have a populated ROM next to the 65 chip. The later board has a custom 68 which does not have a ROM populated. Both boards should be interchangeable. This custom chip is mainly for analog IO on the driving games.

Just match up the ROM jumpers from your old Valkyrie to your Final Lap donor.

Try this before going to the trouble of desoldering chips.

(PS. Final Lap 1, 2 and Four Trax use the old custom 65 if you want to buy a matching donor)

Enjoy! Another happy ending!

And as a follow up post (hopefully dont mind ) i also have few notes about this and can help others to choose the perfect donor .

I tried on the right specific hardwares (gholly ghost & world stadium 93 almost games that will work in the multi , but all works)

Buy the World Stadium 92 On Your Risk

- World Stadium 92 - the game itself works 100% and didnt use DAT area from graphic suboard , but when i tried phelios or other set , had graphic gliches - (no success because custom chip CUS102 was bad) .

Is World Stadium 92 (this game is working correctly, but other games who access that custom chip, have gliches begaviour) .

When he purchased from Japan, the seller only showed this game on the crt (now when we tested with other games we found the culpit - in fact @Hammy discovered CUS102 if is faulty , when lets say , on the board with CUS102 you want to play Phelios, RT2 , etc, then you will see the glitches if that custom is bad)

Does this information is confirmed? World stadium 92 is not good for the multi ? If so it should maybe be removed from the manual as a suitable board for the multi right ? I found one in Japan that I planned to use for the multi but i have to cancel it . Can someone confirm this information ? Thanks

From what I can decipher of @AlxUnderBase's message, he is saying that he bought a World Stadium 92 that had a faulty CUS102 chip.

This *DOES NOT* mean that it's not a suitable donor, it just means that the CUS102 chip isn't used for World Stadium 92, and it can only be tested playing other games that actually use it.

Follow the advice in the manual until @Darksoft speaks on it.

There's no real way of knowing if every chip or area of RAM used by every game are going to be ok until you run the games on the system unfortunately. I wonder if some wizard out there could program a Diagnostic EPROM perhaps?

So this board from ya is presumably bad for the multi ? I could not found the CUS102 where is it located on the boards?
Cheers

Super World Stadium 92 is a good donor but if it has a fault cus102 which takes care of gfx, then obviously games will not work properly.

Cus102 is one of the 2 square flat SMD chips located on the video board.

You mean the cus102 is less good quality, and has risk to be faulty ? In other suitable game what is replacing cus102 ?
Thanks

I didnt said to not buy , i reccommended to not buy and the explanations was as much as clear i can to express my comments . So , if you want to be sure your donor is 100% compatible , dont risk to buy World Stadium 92 , if you want to risk , you are on your own . Yes , World Stadium '92 is good to be used on System 2 Multi , but if the CUS102 chip is faulty you will not know this until you will install the multi or another game on this hardware (i did and tried some conversions before and i know how this hardware works)

@raffy92 ... If you read carefully what ive wrote , you will figure it . also @djsheep explain quite well what i wanted to write / say about World Stadium '92 . It's your money, why not to spend them wisely?

And I thank you very much for the advice. It s not like we can change easily the board so I just want to be sure the board will not be faulty. What is the problem with the cus102 ? Is it less good quality ? The best donor board, what do they have instead of cus 102?
Cheers

 

[raffy92]

As exemple , World Stadium '92 is one of the donor boards where this custom chip is present , but the game (ws 92) doesnt use it and you cant figure if is faulty or not because this game works normally , but if you install other game on the hardware and if this custom cus102 is faulty , you will have GFX (graphics effects errors)



No, is not a less good quality . The best donor board can be any of the mentioned donors . i used golly ghost . You can purchase any like ive told you in my previuous comment . So , take what game you want from that donor list

Does somebody could make the multi works properly with WS92 as a donor ?

Anyway thanks for your comments and advices

My donor was a ws92 and works fine. The issue was that the chip is not used by ws92, so even if ws92 is running correctly, the chip might be bad and other games might not work correctly.

Thanks for sharing your experience

Cpu board are cheap.
Video board is what makes the donor cost so much.

 

[HardAzRockz]

Has anyone paired Cosmo Gang with the multi? I have my multi kit but waiting on replacement capacitors to recap before installation. I recap all my boards and consoles(no exceptions). I’m just a little concerned hearing others with problems.

 

[RepairGuy95]

100% recommend a recap.
I think my problems stem from a poorly serviced cpu board + bad caps.
Multi works great, no problem there.

I wasn’t suggesting my concerns were about capacitors. I’m more concerned about my donor being Cosmo Gang. Yes, agreed recapping FTW

dirtyfoxj has some stuff in the folder...

...and the scripts appears to only be looking for these files? is there a part of the script missing from roms to the above?

10/3 edit: READS THE INSTRUCTIONS AGAIN

oh! ...

re edit and I still don't get it. We need to merge all the chr, name, obj1 and all of these in each of the folders before running the script?!

Also the read me from the valkyrie japan to english is in the folder but not the script! find it here

Hi, is there a more detailed step by step procedure somewhere to make the rom pack ? I am not familiar with mame roms
