I have a gyromite cartridge with converter I opened and replaced the game board with a original Akumajō Densetsu famicom board. Recently I ordered some reproduction chips with english translation of Akumajō Densetsu.

My question is: Will these fit right in? Or does repro chips usually have different outputs for datalines etc so rewiring would be needed? Even though it's not a donor pcb, but the official one? I can just solder them out and swap 'em right?

Not sure. If Nintendo made the board, then probably not. If somebody else did though, maybe. I'm leaning towards it'd need rewired though.

Present a high quality picture from the board which you want to work on it. I am sure it will save time of people who trying to help you.

I think this is the board he's got?

Fixed, heh.

You wont have the extra audio unless you wire a wire on the converter and a resistor in your nes. That being said...are you sure you wanna ruin a perfectly good japanese cart and put the English translation on?

I think Konami VRC series boards need the same rewiring as Nintendo made boards.

While it's a fair question about using a perfectly good japanese cartridge for it, it's less bothersome so long as he doesn't dispose of the original MaskROMs. Although that brings up something I wonder which is what really is the point of having the translation? It's not really a game with much reading and none of it is critical.

Also there are no such thing as "reproduction chips". You ordered either EPROMs or FlashROMs. EPROMs are much more likely.

Hi. Thanks for all the help guys. I have already resistor moded the nes. I will solder a wire on the converter also if I could get some help

I don't really know why I got the english translation either, I just thought I'd make the cart as "perfect" as possible before I played through it, since I haven't played it before.

This is the first cartridge I am "ruining". Im sorry about that, I don't like using donors either, but I wanted the extra sound channels.

Well if you never played through CV3 at all I can understand wanting to be able to read the text. However I recommend the PowerPAK over creating "reproductions". You can still play the games without the work of soldering and the result is the same.

Unless all you can get in your part of the world are PowerPak-incompatible NES clones.

Hilmarf: Do you have an authentic NES or a clone?

I have a original pal nes and a original ntsc nes, so no problem there

Castlevania 3 can't be played on a powerpak.

The japanese version works fine on powerpak.

CV3 for US and Euro version could easily work on the PowerPAK if the MMC5 mapper was partially implemented enough. CV3 doesn't really use too many of its features. But no one has worked on it. The FPGA is supposed to be big enough to support a MMC5 implementation.

So I took on this "big" project for nothing?

I thought the game was mapper MMC5 and the VR6 was a expansion chip, but VR6 is a mapper that's emulated on PowerPak? Or it runs because of the FDS bios or somthing?

If it really runs on PowerPak, I guess I will finish up the project and just sell it o_O

Bummer...or..well...kinda easier and space saving ^^

Both vrc6 and mmc5 are mappers...its just that the powerpak only emulators the previous one. Which is what the japanese version of the game runs on.
