Hello all.
Firstly, I would like to say that english is not my natural language. So, sorry my future mistakes.
I'm purchasing a copy of an original japanese Final Fantasy 3 60pins, and, with it in hands, I will try burn an eprom with the translated ROM for my own use.
I've noticed there is no CHR ROM, only a 512KiB PRG ROM (32 x 16KiB).
I was wondering two things:
1 - The only eprom I will need to burn is that PRG? The others 2 (of 3) chips on the original board doesn't need to be removed?
2 - Anyone knows about REWIRING on this board? I will probably need to do this, right? On Nesdev I just found how to rewiring "TKROM -> TNROM conversion (mapper 4)". I know that FF3 uses TNROM, it's the right conversion?
I will put the PCB scan here too: http://bootgod.dyndns.org:7777/image.php?ImageID=3830
Thank you very much.

You will only need one EPROM, which will be for PRG (512KB). That TKROM -> TNROM guide should tell you how to rewire the PRG connections for the EPROM (I think it's the same whether you're using a TKROM or a TNROM board - someone can correct me if I'm wrong). Do not do anything with CHR - those modifications are only necessary if you're using a TKROM board.
"Last version was better," says Floyd. "More bugs. Bugs make game fun."
That bootgod site has lots of falsified PCB scans, the most obvious fake is their Super Mario Bros/Duck Hunt PCB. Where's the glop tops? Real version here.

So, I will just need to do this?
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)
About those Nintendo boards with a "black drop" instead ROM chips, it's very strange. Some japanese versions uses this, if you look at Donkey Kong for Famicom (probably the first Famicom game), you can see it uses that "black drop" too.
But I think there's no (huge) variantions of Final Fantasy 3 (J). I don't have the copy of FF3 in hands yet, but probably will be the same (I hope).
Thanks.
If I get this works, will post pictures later.

That is one of the oddest comments I've ever heard You can see an example of the epoxy board here.Dwedit wrote:That bootgod site has lots of falsified PCB scans, the most obvious fake is their Super Mario Bros/Duck Hunt PCB. Where's the glop tops? Real version here.
The epoxy board seems to be the most common, but they actually made a whopping 5 revisions of the "standard" board as well.
I would imagine that the cost tradeoff for epoxy boards differs depending on the production volume. A pack-in like SMB1/Duck Hunt was made in such large volumes that the cost saved by switching away from DIP made up for the added expense of setting up a glop-top production run.drk421 wrote:If epoxy boards are cheaper, why not use them for all games?
I am giving u link to my gallery. When my buddy was making FF3Eng from my Rockman 4 (pirate). Maybe it will help with making FF3
