Clean as in the original japanese dump?

Well, when i went today to make my second ff3 and prepared the rom with the pal patch and compared it to my first one it was smaller by .200kb....Yup i used an overdump the first time*face palm*

I sorta got side tracked half way through so its only a 1/3 finished, but i did promise picies so here is my retarded first born and its lil bro

Any chance of a better pic\diagram? I can't see jack on that pic aside from a rats nest of wires.

TKROM -> TNROM conversion (mapper 4):
PRG socket:
Bend up pins 1, 2, 24, 30 and 31 (or cut tracks 2, 24, 30 and 31)
Solder pin 2 to hole 24 (A16)
Solder pin 24 to GND (OE)
Solder pin 30 to hole 1 (A17)
Solder pin 31 to hole 2 (A18)
CHR RAM conversion:
Seat the RAM chip 2 pins back (pin 1 of RAM is pin 3 of socket)
cut track to hole 3, 22, 24, 28 and 29
Solder pin 1 to hole 30 (+5V)
Solder pin 20 to hole 31 (CE or CHR /A13)
Solder pin 22 to hole 2 (OE or CHR /RD)
Solder pin 26 to hole 28 (+5V or RESET)
Solder pin 27 to NES pin 56 (CHR /WR), you will probably need to glue in the missing tab on the PC board that goes into the NES, I used a thin piece of metal and super glued it, then sanded it with fine sand paper

I already know the pinout and how to make FF3 I just wanted to see some nice clean pics finally posted for a visual "how to" so when noobs ask they can just be pointed to a thread like the diagrams I made up for expanding the CHR size on a CNROM for making the penasian titles and the diagram I did for making MMC3 carts.

You dont need a full pin SMB2 to make a FFIII, you can use a standard TKROM and add a pin (takes about 20 seconds)

I have a full-pin SMB2 that I'll let go for a fair price (whatever that is)....

how do u add a pin, i have only 1 full pin smb2 and i wouldnt mind practicing on a regular tkrom cart first

I think someone mentioned successfully gluing a thin piece of metal to the board... I can't see how this would work well though.

drk414 also mentionned that method in his EPROM rewiring document years ago. I even remember seeing pictures of the board with a pin added. It's definitely possible - but yet for some reason the rumor that a full-pin cart is needed took the main stream of boot leggers.

I actually removed an edge connector pin from an old motherboard for an ISA slot, straighted it and superglued it to the TKROM PCB.

Here are some pictures of the cart I made:

Definitely the way I will go with this, since I do not have any diodes left and I have a couple of extra kirby's adventure carts lol

Anything is possible, but if you want a PCB that will work after 100+ insertions (especially with one of those new front loader slots that put the grip of death on the PCB) than a full-pin cart is the only way to go.

Those pins are not glued during production, they are actually part of the PCB and etched out, hence the best and only method I recommend of reproducing FF3j.

So whats the final verdict on the correct parts and order to use them to add the battery please? I know this is a nero-dump but I got some extra pcbs without batteries I'd like to use for some FF3 greatness

It might be simpler than you think of...

On a TL1ROM to TNROM conversion I just had to add pin 56 using a stripe of copper taken from some scrapped board ...

Because the SRAM is already 28 pin and the board only takes 28 pin chips, I decided on making it into a TGROM/TNROM compatible board.

I used an 62256 chip instead of 6264 so the only pins I needed to mod was 1 (A14) and 27 (/WE). /CS and /OE were re-routed at the 74LS32 (which was removed) place by connecting pins 2 and 3 of the removed 74LS32 together. Pin 1 was connected to the trace that goes to pin 22 of the CHR chip and trace for pin 1 of MMC3 (CHR A16) was cut. This resulted on all 32KB of the SRAM being visible for the PPU through the CHR banking mechanism of the MMC3 chip. Non standard I know, but I don't think it would hurt any game ... And I ended with a very clean layout.

An 6264 SRAM was soldered behind the PRG ROM connector (this is a DEV cart, not a game repro so it's socketed) and proper connections were made for the MMC3 chip pins. This is non backed up WRAM configuration similar to that of the TKROM board.

Actually you can use ANY board with the mapper chip you need. No need to hunt down some rare kind of cartridge. This cartridge in particular was a broken copy of Double Dragon 2 (PRG ROM was fried, getting hyper HOT) and because it was slightly useless for making a devcart (no room for CHRROM socket) I decided to turn into CHRRAM type. 8)
