When I got sound issues making my shinobi cart, I changed the prog board for another one, worked but I don't know what was the problem with the another one.

You can't use 27C322 for the V eproms, the maximum supported is 27C160.

I can post a photo but not right now, I'm home and the board isn't here, but I'm sure that the JVS card isn't there, I have to find one 7900gs and the JVS card. Maybe you can see thru the video I posted the missing card.

I don't have the JVS card at all, I can't put any JVS IO because of that, maybe I should give up and search for a complete type x2, I couldn't find a JVS card anywhere, even infos about it are so hard to find.

Yes, I'm trying to boot w/o a JVS IO, I don't have the JVS card to connect JVS IO. I tried with a 7300gs just to see if it would boot and to make sure it was written correctly on the HD.

Once again struggling with arcade hardware….. I’m trying to do a multi for my X2, put an image that Niko pointed, I used HDD Raw to write the image to a hd. After that opened in Windows and I see the 3 partitions, ttx something, I don’t remember right now the names. Put the hd and all I got is a...

The taxes have gone up absurdly, importing the video card would be the last option, I still have to search in some places but it has to be in person, if I can't do it I'll send you a message and thanks for the help.

Hi there, Can I use this tool to flash a GF7300GS? I can't find any 7900gs nowdays.

Golden Axe solved, changed the cha board....

Shinobi solved, it was a bad PCM.

It's a 27C1000, no need to swap pins, S1 is for the fix layer, if S1 has any problem, the credit coundn't been seen, or health bars. It's dirty but there is no rust, I don't want to kill another cart just to test it, I'm gonna to take out the eprom from cha board that I assemble Shinobi to see...

Now I'm the one having trouble making another shinobi cart and a Golden Axe cart. Shinobi have sound problems, reprogrammed and verified all V roms, verified M1 too, jumpers checked too, its the same config that I have made in the first one that works. Golden Axe I have graphic problems...

Well I don't have a lot of eproms avaliable, so when I buy It I prefer to buy larger eprom so if I need more space I have one that suits, if its not the case, I just double the file. I prefer that than buy different types of eprom, here in Brazil I don't know a good place to buy it, and when I...

I've made one, this is what I used M1 - 27c010 S1 - the correct one is 27c1000 non jedec but 27c010 can be used if you made a pin swap between pin 2 and pin 24 V1 and V2 - 27c160 C1 and C2 - 27c160, I don't know if 4096 can be used. P1 - 27c800 if used on P1 or 27c4096 i used on EP1

I'm planning to make a Golden Axe cart, I konw that I can use 27c010 for S1 instead of 27c1000, but now I got some 27c1000 and would like to use it in S1 but my programmer doesn't flash 27c1000, it's a TL866CS. If I swap the pins in 27C1000 could I flash it as a 27C010? Should I disable check ID...

I tested in mame, I got no bars until I take a hit. The game play and feel like the original one, I finished the game and didn't found any other glitch.

PROGTOP or PROGBK1

PROGGSC have 3 slots for V Rom, and Shinobi have 4 V Roms, the maximum eprom supported for V Rom if I'm not wrong is 27c160, If someway it's possible to use 27C322 for V Rom you can use PROGGSC, if 27C 322 eprom can't be used you can't use PROGGSC PROGTOP and PROGBK1 can be used.

Little update: I found the problem, it was the MVS, what i can't understand is why more than 10 games worked and just the one I was doing isn't, anyway it's done, thanks for the help... @pierpa86 @nem

Yep, i've tested another games and got sound from all of them, so my mvs is ok, I should have tested the carts that I removed the mask rom before I removed the mask roms, but i didn't. I have checked the PROG and CHA boards with a magnifying glass, the pads were I solder seems ok and the tracks...
