Playing Akumajo Denetsu(JP Castlevania 3) PROPERLY on us nes?

[Kamino]

So, I went insane and bought JP CVIII at the MGC.
At that time, I seemed to recall seeing schematics somewhere for a switch that could kill the pins that block the custom graphics and sound chips inside this cart - however, upon arriving home, a google search came up dry.
(I suck at google.)
Anywho, I'm NOT talking about the lockout chip disablement - i already did that to my toaster, and primarily rely on a toploader anyway, which has no lockout.

Is there any way to play this game right proper on a us nes, or do I have to bite the bullet and throw away $100 on an a/v famicom???

to my knowledge you need a famicom...i've never heard of one running on an NES

[walrusmonger]

From what I remember, the game has some fancy thing inside that makes the music kick ass. The US NES doesn't have the proper hardware inside to play this, so it wont work.

This is from what I remember, so I could be wrong. I also bought the JP CV3, but have yet to play it on real hardware since I'm not spending the $$$ to get a Japanese Famicom for 1 game

Akumajo Densetsu uses the VRC6 chip, which is completely incompatible with the NES. Even if you were to build a switch to block the chip, and it worked, it would be pointless as any advantages of playing it over the US CV3 would be lost.

I bought an old RF Famicom years ago to play it, no regrets here.

THe Famicom is like the SNES. Where the cart itself could be an entirely diffrent system for you to run whatever you want. CV3(J) has special chips that gives it an extra boost of graphics and sound.

Think of the cart being a Super Gameboy but with a rom trapped inside.

The NES ( and Euro NES ) had various things removed from there model. I think it might have been dew to lockout chips or the VHS like shape of the system itself.

it was cost cutting.

Does the VRC6 chip generate and output audio in such a way that you could tap the audio as it exits the cartridge, and then mix it with the NES' audio output? Or does the output from the chip need to be further processed in the famicom itself before sound is generated?

I thought you just had to connect one pin on the cart slot to something on the bottom port...maybe I'm thinking of something totally different. You're better off posting this at the forums on nesdev.parodius.com.

This guy is on the right track.

The reason CV3 won't work on a toaster is because NoA, in their infinite wisdom, moved the required pins to the expansion slot, located on the bottom of the toaster.

Basically... buy an AV FamiCom.

It SHOULD work using a converter- you won't get the extra sound channels, but the game should be entirely playable. If not, something's wrong with the converter.

Anyway, once the game's up and running, you'll need to make a hardware modification to both the converter and the NES to get proper sound. The modification is described in the NESDev forum somewhere- you'll have to do a search because I can't remember where it is off the top of my head.

Can you just solder the chip from the expanion port to the pins on the NES

Yeah, I assumed that it was assumed we were discussing getting the VRC6 to work properly on a NES, not so much the actual game, which will run perfectly fine on a NES with the proper adapter.
