About namco system 11 c431 keycus(dancing eyes)

[twistedsymphony]

Could it be done similar to the cave project?

the first step in any Multi is making all of the conversions work.

it might be possible to make a multi but you've got to get through that step before you start speculating on the best way to do it.

 

[Hammy]

Well, clatGPT is wrong

 

[Hammy]

Good news tho, xevious 3d seems to do a couple of small checks and that's all.

EDIT: Cracked it i think

 

[Hammy]

prime goal is a few easy checks too ..

So the only 2 that are a problem so far are dancing eyes and pocket racer...

dunk mania i have not checked yet

Dancing eyes makes sense, i can see what's going on, but pocket racer is a bitch (of cause, because it's the one i want the most LOL)

 

[pierpa86]

Guys I just repaired my first system 11, (tekken 2) unfortunately I don't understand much about cracking/disassembling and reprogramming.
But I'm ready to test on my hardware when there is something to test.
I would really like to convert the board to DancingEye.

 

[Hammy]

Done but not tested in hardware, if you want to be guinea pig??;

Dunk Mania
Xevious 3D
Prime Goal
Star Sweep

..

Tekken 1 is unprotected as standard.

Not done;
Tekken 2 (not checked)
Dancing Eyes (do-able)
Soul edge (not checked) (this one protects the background colors)
Pocket Racer (hard)
Quiz Angel 3 (not checked)
Point blank 2 (not checked, think easy?? But requires gunboard)
Bust a move 1 (not protected but requires CDDA board, CD drive, CD of audio + dumping)

 

[pierpa86]

Thinking about, test it on real hardware.....
i'm so exciting
This is the memory plan guys:

ROM8 PCB - IC: 1,3,4,5,6,7,8,9=8
Original: MB8316200B
Spare: MX29F1610

IC:6D
Original:Intel 28F200BX-T80
Spare: PA28F200B5T60

IC: 2F,2J,2K,2L
Original, still available on ebay: 28F008SA-120

IC: WAVE.8K 32MBit
Same MVS problem, there is no 42pin DIP EPROM in Byte mode that you can buy ! only 27c322 in word mode
Anyone have pinout of original maskrom ?
If we are lucky we can use the adapter made from ACK granmaster jedi ! for MVS !

Have been making my own bootlegs for fun and (no) profit and realised that the lack of a pin-compatible 64mbit (8 meg) EPROM for C ROMS is a limiting factor for some of the larger games. Also the lack of a 8-bit addressing 32mbit (4 meg) EPROM for V ROMS is a bit of a pain, requiring them to be split onto 2 x 160's.

A lot of the Chinese bootlegs just bodge 3.3v chips straight onto the board with 5v signalling which works great until it stops working.

Luckily the awesome Tdaede considered this problem a long time ago and solved it with this adapter. Takes super-cheap 3.3v flash, adjusts...

I have already used it and and still have some pieces available, so i can use: MX29LV320EBTI-70G

WAVE.8K - Sound samples, 42 pin DIP mask ROM, either 16MBit or 32MBit. If 32MBit, it is programmed in Byte Mode.
SPROG.6D - Sound program, Intel PA28F200BX 2MBit Flash ROM (SOP44)
PRG.2* - Main program, Intel E28F008SA 8MBit Flash ROM (TSOP40)

What you think about guys ?

 

[Hammy]

Long winded hex to decimal "counter" ... needs to be translated into MIPS
(yes, this is how i would lay out a "program", then i'll re-make this code pretty similar with an opcode generator, i don't get along with compilers...)

There's more efficient ways for sure, but this should work for a test run without thinking too hard.

---------

save 2 reg's (if required)

read hex into reg
zero a reg for dec reg

>>

test hex reg 00000000
beq >end

>START
add 1 > dec rec
check deg reg xxxxxxxA
beq >1

check dec reg xxxxxxAx
beq >10

check dec reg xxxxxAxx
beq >100

check dec reg xxxxAxxx
beq >1000

check dec reg xxxAxxxx
beq >10000

check dec reg xxAxxxxx
beq >100000

check dec reg xAxxxxxx
beq >1000000

check dec reg Axxxxxxx
beq >10000000

sub 1h hex reg
check hex reg
bnz >START

-----------------------
>end
store dec reg
restore previous reg's
out

-----------------------

Star sweep only needs the CPU roms, and sound roms - the romboard is not required for this game, and it would be the easiest one to test this proof of concept.
The chips onboard can be re-used .....
Except the funky mask rom (it's a strange rom... but i think the guru has designed an adapter for 27c160 maybe? or some tekkens have a rom adapter fitted as standard)

2x 27c160 adapter is wellcome.
Also any information about wave.8k pinout.

 

[pierpa86]

Good morning guys !
What i choose to buy in order to test this rom on my hardware:
All follow IC are easy programmable with my Xgecu T56

IC: 1,3,4,5,6,7,8,9=8 - SOP44
MB8316200B - Datasheet
MX29F1610MC-10 - Datasheet - where to buy

IC:6D - SOP44
Intel PA28F200BX - Datasheet
PA28F200B5T60 - Datasheet - where to buy

IC: 2F,2J,2K,2L - TSOP40
E28F008SA-120 - Datasheet
LH28F008SCT-L85 - Datasheet - where to buy

IC: WAVE.8K
32MBit DIP42 Byte Mode Maskrom
MX29LV320EBTI-70G with ACK adapter (maybe this is my plan)
Any other advice is welcome

Order sent, its seems arrive at 16 June, i'll let you know !
the best test I would do would be with : 1) Dancing Eye, 2) Xevious
I don't want to unsolder the board too many times, I would like to limit myself to targeted tests.

 

[nem]

I would be happy to test Star Sweep.

what you think about WAVE.8K ?
Do you mind a solution ?

 

[nem]

Well, there's this:

https://www.neo-geo.com/forums/index.php?threads/27c322-as-a-32mbit-v-rom.223340/page-2#post-3386341

No idea if it works.

 

[Hammy]

I would be happy to test Star Sweep.

Sent! let me know how it goes.

 

[pierpa86]

Good news guys !
In the meantime, while I wait for the memories, I wanted to do a test with the ACK adapter as Wave.8k on my Tekken 2.
It works!

 

[ForestOfDreams]

I think 1,000 writes is enough for most people.

However, if one was to exceed that, is there a modern chip one could replace them with that is pin compatible with higher writes as an option?

Its write times, you write only 1 times when you put game on its not possibile to exceed that.

 

[pierpa86]

in the meantime i found another Tekken 2 at good price so i can test more !
Can i ask you @Hammy if you have done progress on Dancing Eye, is it working now ?
I still waiting for memories from suppliers

When you are ready please send me Xeviuos 3d and Dancing Eye, i will test it really soon.

Greetings to all !

 

[Hammy]

No, not done dancing eyes yet, that code above needs checking over / translated to MIPS (and then patching into the game).

Xevious 3d is done, but lets see how @nem goes with star sweep first, there's no point doing a difficult one until the conversions are known to work.
