Re: Castlevania III MMC3 hack
I'm pretty sure this site doesn't allow hosting copyrighted ROM files. Maybe post an XDelta or BPS patch instead.
I can see a lot of bugs regarding which mirroring mode is used. Since MMC5 lets you pick mirroring modes easily, and so does the MMC3, this seems like it won't be that much of a problem.

Re: Castlevania III MMC3 hack
Do we even have policies regarding that since moving away from the Parodius Network?
(BTW: The NESDev front page still references the old Parodius policies.)

Don't do anything that could cause Nintendo or a major seller of VC games to get this whole site taken down.
Re: Castlevania III MMC3 hack
Apparently you can't even get in gameplay with this hack.
I think it should be hard to go with MMC5 -> MMC3, especially because of PRG bankswitching which is 8k, 8k, 16k on MMC3, but 16k, 8k, 8k on VRC6 and the MMC5 mode that is used by CV3.
If this would have been possible, Konami would have done it really. It would have saved them much costs.

Re: Castlevania III MMC3 hack
Two things might help:
- Does CV3 normally put anything in $6000-$7FFF? If not, something that'd normally be in one of the switchable banks could be relocated to PRG RAM there.
- Does CV3 use the DMC? If so, the music can be rewritten not to use it, freeing up $C000-$DFFF.

CV3 didn't use $6000-$7FFF,and $C000-$DFFF selected when Dracula is lauging.tepples wrote:Two things might help:

Re: Castlevania III MMC3 hack
So, is this possible?, do we have a CV3 in MMC3 mapper, that would become really nice for a multicart..

Re: Castlevania III MMC3 hack
Yeah i was alway's wondering how Castlevania 3 would run on a mmc3 chip ,as i just don’t think that this game will really take much benefit from the mmc5 chip ,other then using 16K bankswitching and/or possibly in a different way as well,but what if we can reverse engineer this game somewhat to make it fully compatible with the mmc3 chip with possibly some compremises ,that would be really interesting.aarkay_14 wrote:So, is this possible?, do we have a CV3 in MMC3 mapper, that would become really nice for a multicart..
The main reason why we want to see this game running on a mmc3 chip is because to make it compatible with the powerpak,multi rom carts ,famiclones and emulators whose don't support the mmc5 chip:

Re: Castlevania III MMC3 hack
Just registered to post in this topic.
Is there any update on this? I've tried it on emulator, mostly works except for the intro and some minor glitches. I've never played past the first lvl so I don't know if there any other glitches, but I would really love to gave a famiclone compatible version on a cart.
Any news?

I'm sorry to be late,after that,i did more.now it is completely playable.vertical stage is complete success,no buggy tile in state bar.
But some error.the opening screen is wrong,flood IRQ also lag,and it small probability cpu jam.for use dpcm IRQ,some stage no attack se and bgm lost dpcm drum.saya and alucard in speak screen was buggy,last battle is random laser.i will continue to do.
My English is very poor, please forgive me:P
I also had made a CV1 hack that use MMC3+128PRG+128CHR.now I made a Castle 3-in-1 mitulcart by mapper 52,so funny.

Re: Castlevania III MMC3 hack
That's great!
Any patch available?

Re: Castlevania III MMC3 hack
There were some glitches with stairs too, character would simply fall down and die when passing near the the stairs. If you could provide the patch I'd continue further testing.
Keep up the great work!
