Doing a progear and am a little stumped.
I see there's simm 1 a,b,c,d and so forth but do not know what slot that would correspond to with eproms.
My best guess is simm 5 is slot 11 and simm 6 is slot 12 but beyond that I am lost.
Can anyone please shed some light on this?

I have something that might help you. Check the PM I sent you...
 
First attempt at doing a conversion. Was hoping someone could confirm if my config is correct. Trying to convert a SFZ3 to a Marvel Vs Capcom. Already have an Alpha 3 and this board had suicided, also the original maskroms were all corroded. Cleaned up well fortunately. So I have the PALG that was in SFZ3 so should be good there.

have the following for chips
Slots 1-2 27c010 (two diff manufacturers but shouldn't be a prob, let me know other wise)
Slots 3-10 27C4096
Slots 11-20 27C322 (all rom files I have for these are 4096kb so assumed I needed these even for the sound roms which I thought MAY be odd...maybe not)

my jumpers are as follows
SOOS-SO-OSOSOS-SOSOSOSO-SOSOSOSO

I burned the the MVCU 980123 version encrypted roms and installed a Undamned Infi Key with the following Jumper Settings. MVCU 01010000

Not getting anything on the screen at all yet. Any thoughts?? See attached photos for some pics of what the board looks like right now.

1) different manufacturers for roms doesn't matter but the speed does. It's the -xx number at the end of the part number printed on the chip. Must be equal or better to the original speed to be safe
2) are you able to burn a suicide tester rom? That'll tell you if the board is basically functional and you aren't chasing deeper issues than just pal, new roms and jumpers.

3) sometimes corrupted decryption key data gets stuck in the ic. Short the 3 points of exc1 for a minute or so to ensure it is cleared.

Checked all mask EPROMs, zero issues, so I started to check schematics online to trace the 2 pins the 4MBit EPROMs are not using.

GFX Address A20 is not available when using these 40 pin mask EPROMs.



Same with gfx address A21




By tracking the traces, indeed, this address is not available (duh).



So, I decided to burn these 4MBit EPROMs in M27c160s. Doubled the data, just in case. Tried jumpers as OSSOOSSO-OSSOOSSO and SOSOSOSO-SOSOSOSO.

Exactly the same freaking result. I reinstalled the original mask roms and decided to store the pcb until I have either another board to test or somebody with a 19xxjr2 pcb willing to share the B Board revision and the jumper settings.

Hello man I know this is a very old post but I stumbled upon the same issue with the exact same corruption you showed earlier.
Turns out the jumpers were wrong, credits goes to plasticfactories horribly suicide damaged 19XX board for saving the day OSOSOSOS OSOSOSOS

Is there a non broken link to junper settings ?
Currently in need of Tower of Doom and Alien vs Predator both Euro Phoenix.
Using 27c322eproms in 11, 13, 15, 17, 19
27c4096 in 3-7 and 27c010/1001 in eprom slot 1
 
You need to take progear jumpers config. (you use 27c322 on 11-12 and 13-20)
Take care to have the good jumpers for 01 and 02 (JEDEC or NON JEDEC).
And use a Pal G.

Revision of these board ?
 
Rephrase of my question above:
How do I use the excel-sheet with conbined 27c322 in 11,13,15,17,19 and the rest of 12-20 empty. What do I select for 12-20 27c160 and 27c322 are the only options (nor empty)
 
Merge with copy /b binary is already done, what I'm currious i about the choices in the excel sheet for the slots that are left empty: 12, 14, 16, 18 and 20?
 
Hi, looking for some help with setting jumpers and thought this might be the best place to ask.

I’m looking to swap over the original roms from a Rockman 2 Power Fighters board that has a graphical fault into a working donor board. The original board is a rev 4 and the donor board is a rev 7.

For the jumpers is it as simple as matching them to the original board, or do they change depending on the board revision? Was presuming they’d stay the same but I’ve seen images of Rockman 2 with a different jumper 1-13 config to the board I have.
 
Really need peoples help here and I'm very much a novice in if this is even possible to do...
So from reading different stuff, it is possible to convert a green CPS2 game (such as XMEN) to run SSF2X.
However it seems like I will need to swap romset/PAL chips and even the security chip (unless I use phoenix).

In terms of reprogramming I may not be able to use the same chips due to the EPROM size. So would need a new set of chips also.
Ive tried searching but cant find anyone who offers a service of selling a new romset of chips (guessing to allow me to plug and play), so I would need to acquire a programmer and a source for chips (are these available on the market).

I'm assuming that nobody does this due the cost of this outways the cost of finding an original a SSF2X board and just buying that?

Anyone able to clarify or provide some insight to even if this is just a stupid idea!
 
If you are getting into rebuilding boards the cps2 platform is a good place to learn the ropes.
Ali or ebay for chips.
Jumpers are set based on pal/gal letter.
T76 programmer. You can go cheaper or more.

You can absolutely convert your X-Men to SSF2X

Yes you will need to replace all the ROMs - factory ROMs for graphics and sound are mask ROMs. Data is burned onto the ROMs during production

PAL will also likely need replacement

Even if you have all of the replacement ROMs this is not going to be plug and play. You will need to set the jumpers using a soldering iron and a knife depending on the current settings. You will also need an Infinikey/OpenKey or an Arduino configured for key programming if you want to retain encrypted original code. Or you can run the Avalaunch or Phoenix set

You can buy EPROMs and have them programmed at the same time from somewhere like buyicnow but if this is something you are potentially looking at doing again in future a programmer is a good device to have on hand

As @RepairGuy95 said, CPS2 is an easier platform to learn how to do a conversion

Is there any issue on Armored Warriors (Powered Gears) conversion?

I'm trying to make a convert for a friend and i have much weird issues:

Tried to burn the complete Phoenixed set (Eu version) and i had a Error screen

So, decided to make the conversion set: All roms are JP version, PRG roms on 27C4096 decrypted (Avalaunch).
The game only boot with a PAL G (tried F - D - B, black screen)

Now the game boots, sprites are all OK (Only 27C322 used) but the sound is broken. Made the strap between Pal G leg 9 and C13 à CN3

11 & 12 are 27C160 eproms

I have sound but some sound missing in menus, also there is a strident sound in game.

Any help please?
Thank you all

Did you ever solve this? I’ve also been having issues with Powered Gear decrypted roms. The graphics are fine, although I had to use PAL-G, but some of the sound effects are off. I tried changing the audio jumper settings, but it didn’t make any difference.
My board revision is 93646B-7.


Edit:
Eureka! I solved it!
I searched online and noticed that most Powered Gear boards use PAL-D chips. I swapped in one of my spare PAL-Ds, and voila the audio issues disappeared!
Jumper settings:
SOOS-SO-OSSOSO-OSSOOSSO-OSSOOSSO
So yeah, don’t get too hung up on the list that’s been floating around. I also noticed my Street Fighter Zero is in fact PAL-E.
