TENGAI/SENGOKU BLADE PCB.........(REGION CHANGE??)

arkadia74 · Post by **arkadia74** » Fri Jun 13, 2008 4:45 am

Hi
I have a psikyo's tengai(english ver) pcb and wonder how to change to sengoku blade (japanese ver).
I think romset of tengai includes all languages.
Please let me know how to change ver.
anybody?

Thanks.

On the strikers boards, the region switch is with a jumper (missing jumper)-- just two solder spots you either short or un-short. I can try and find a pic of the spot. Search here for strikers 1945 or dragon blaze region switch and a pic might come up (that's how I learned it).

You can even short it with a pencil line to try it out.
Differences should be language as well as ability to continue through last levels (japanese version sends you back?).

where is the jumper???

I found only one jumper (JP1) on tengai board.When I cut the jumper,the game did not work.I think JP1 is not for region.

Can you supply pic??
I did not find any data here.

here's a little info on that.

I looked up the pic and board on system 16 and it looks like tengai runs on the hardware previous to the one I was talking about.
So sorry, I guess my idea was bunk.
It also looks like strikers 1945 is the tengai hardware, but 1945 II, III, and Dragon Blaze are the other with the easy region mod.

yes,you are right.
striker 1945 and tengai are same board.

sorry,the info for 1945 II, III, and Dragon Blaze are not helful..
because tengai board has not jumpers like 1945 II,III and Dragon Blaze.

Thanks~

Could you please supply us with a hi res picture of your PCB ?
The easiest is to put it on a scanner. In the MAME source code
it looks like there is a jumper check.

are there any play differences between the Japan and World versions?

This dip switch settings are incorrect, the manual says bank 1 is coin and the ones in bank 2 are the normal game ones. There is no language selection.

If someone could provide a hires picture of a Tengai PCB we might know a bit more.

Looks like oxtsu beat me to it

Could you be so kind to take a detailed picture of your entire PCB ? The easiest method is to scan it.

-shotgun assist for rtw-

I wonder if those 'jumpers' below dip banks 1+2 (with the serial# sticker covering them) are the supposed region change dips.

That's what I am wondering as well

It would be interesting to compare these jumpers between a Japanese and World PCB. The MAME source code indicates that there is a jumper block somewhere.

However it would be nice to have a picture of the entire PCB just to make sure.

Nice image antron

I cannot see anything else than the normal DIP's, the points covered by the sticker and JP1.

Based on the test done by arkadia74 JP1 is not of any interest.

antron, could you please take a closeup picture of the DIP area on both sides of the PCB ? I'm interested in u33 and to the edge of the PCB.

Does it feel like there is something underneath the sticker ?

Does anyone here own a Sengoku Blade PCB ?

rtw

antron · Post by **antron** » Tue Jul 15, 2008 10:36 pm

one row of the points covered by the sticker go to the external (EXT) points on the edge and end. the others go to U43. they look like expansion inputs that would have the option of being disconnected.

edit
no, the inputs would go through resistors where the sticker is.

Here are a few things to try

. Try starting the PCB without EPROM 4 (U59)
. What kind of chip is U33 ?
. Get a peek under the label.
. Take a picture of the DIP area from the other side
. Lift the program ROMS's and see if there are any pads underneath.

has anyone fired this ROM up in MAME to see if these fabled dip settings exist and do anything?

antron · Post by **antron** » Tue Jul 15, 2008 11:44 pm

U33 is a MB3771, Power Supply Monitor

I have, it goes from Tengai to Sengoku Blade.

antron · Post by **antron** » Wed Jul 16, 2008 12:07 am

There are no pads under the roms.
Without EPROM 4 the board will not go past the system tests.

antron, your PCB picture reminded me of something I had seen before

http://www.world-of-arcades.net/1945/St ... rdware.htm

It's the same PCB and according to MAME you can change regions in the world version of the ROM. If I change the version to USA in MAME I will get a region warning on power up.

I own a strikers 1945 PCB so I have checked a bit more

I suspect R9, R10 & R11, they are all connected to 5V i.e. pull ups. And their tracks lead to the same chip as the DIP's.

It is late I will look closer at it tomorrow, feel free to desolder one or all of them

antron · Post by **antron** » Wed Jul 16, 2008 1:34 pm

maybe arkadia74 should compare my picture and his board and look for differences.

according to mame we should be changing just one item.

rtw · Post by **rtw** » Wed Jul 16, 2008 2:26 pm

arkadia74 has a Tengai as well, he wants a Sengoku Blade.

I have asked some other people as well.

And it would also be interesting if anyone on this board owns a Strikers 1945 with the USA region warning on startup to photograph their PCB.
