Does Anyone Own a Gundhara PCB?

[twistedsymphony]

I'm hoping someone here own an original Gundhara PCB that can help me with some component part numbers and maybe take some photos for me.

Primarily I'm trying to find what ICs are used on U2-1, U2-1, U5-1, and U5-2 (the SMD RAM chips on the back edge of the PCB)

@ShouTime or @parodius can you help here please ? Thank you

 

[parodius]

Sure can.

They are NEC D43256AGU-10L & D43256AGU-12L.

(yeah my Gundhara board is in not so great condition - looks like a cap has leaked on it from another board maybe ?)

Thank you! @parodius

Actually that is flux remains, you can remove it with some rubbing alcohol.

So I own this Zombie Raid pcb and I see that Gundhara would be a much better game. Anyone ever did a conversion? there are differences in the board but a LOT of exactly the same thing!

thanks to @caius repair for this Gundhara picture:

and my zombie raid:

not possible without the PAL Dumps from Gundhara.

Even if the hardware isnt 100% the same ? (ive noticed some differences in logics side , in the top of pcb

I started working on this years ago (this thread was created while I was looking into it). it's stuck and can't progress further without those PALs though.

I have several other conversions on this hardware that have progressed a way, also stuck due to not having PALs.

well... I picked up a KRRAZZY bowling yesterday for a big whole 5$ so one more in the pot !

ok ... so for gundhara AND Zombie Raid, MAME list the pals as :


ROM_REGION( 0xc00, "plds", 0 )
ROM_LOAD( "fx-001.u206", 0x000, 0x104, NO_DUMP )
ROM_LOAD( "fx-002.u116", 0x200, 0x104, NO_DUMP )
ROM_LOAD( "fx-003.u14", 0x400, 0x104, NO_DUMP )
ROM_LOAD( "fx-004.u35", 0x600, 0x104, NO_DUMP )
ROM_LOAD( "fx-005.u36", 0x800, 0x104, NO_DUMP )
ROM_LOAD( "fx-006.u76", 0xa00, 0x104, NO_DUMP )


ROM_REGION( 0xc00, "plds", 0 )
ROM_LOAD( "fy-001.u206", 0x000, 0x104, NO_DUMP )
ROM_LOAD( "fy-002.u116", 0x200, 0x104, NO_DUMP )
ROM_LOAD( "fy-003.u14", 0x400, 0x104, NO_DUMP )
ROM_LOAD( "fy-004.u35", 0x600, 0x104, NO_DUMP )
ROM_LOAD( "fy-005.u36", 0x800, 0x104, NO_DUMP )
ROM_LOAD( "fy-006.u76", 0xa00, 0x104, NO_DUMP )

So are they the same or are they just at the same location? we don't know cause they are not dumped?
dumping them is probably not trivial and not something that I can do but is there anything that my zombie raid board can help with? if so, who could do it?

 

[twistedsymphony]

it's possible that some are the same but some are definitely different.
