Re: Oversize FDS disk images

Well FDS homebrew scene is possible. Probably already had a couple? Not sure what the limitation would be since FDSEmu and FDSStick are out. Who's to say there can't be a 6 disk, 12 side game?

Re: Oversize FDS disk images

Theoretically couldn't Famicom Disk System be added to NES 2.0 under Extended Console Type with a few reused redefinitions of the standard "PRG-ROM" area as "Total Size of Disk(s and Sides)"? Mapper 20 could be used. There could be another reused area for number of disks and size per side. That way ...

Re: Oversize FDS disk images

Correct me if I'm wrong, but it doesn't seem that the Game Doctor images are even being talked about. Have we gone through the process of converting them into a current, working format or are we going to butt heads and masturbate egos? Are they FDS or Famicom games? (At any rate it's pretty interest...

Re: NSF Extensions, NSF2 and NSFe (2018)

That may be the case, but accurate emulation of the expansion sound hardware is why we have such vibrant chip music communities. Might as well shove the YM2413 (K-663A) in NSFPlay and quit whining, bro. :) Also, I think there's some rhythm mode in the Noraebang songs so VRC7 wouldn't work.

Re: NSF Extensions, NSF2 and NSFe (2018)

...though, by the same token the Karaoke cart could be ripped to use VRC7 registers instead of requiring its own expansion bit, too. I guess that'd be not hugely different than the existing VRC6 situation (just now a mandatory chunk to indicate YM2413, which I need anyway for the TNS stuff that doe...

Re: NSF Extensions, NSF2 and NSFe (2018)

All of those Jaleco with the ADPCM use different registers for sample playback. Is there a need to have them use all the different registers or can we just rip them to use one that doesn't interfere with other chips?

Re: NSF Extensions, NSF2 and NSFe (2018)

Sounds great! There is the case of the M50805 and the Jaleco ADPCM sample chip carts for SFX one-hits in the NSF to have expansion bits; and other known expansion audio pirate carts like City Fighter. The sample data will need to be held within the meta-data at the end of the NSF2. It would also be ...

Re: Namcot 163/MMC5/Konami VRC6 Audio Level test program

I guess you can check Sean Riddle's webpage for M50805 levels for Family Aerobics Studio. The Jaleco level test program could just probably swap through all the different mappings for the chip.

You got source for these things? :)

Re: Family Noraebang (패밀리 노래방)

krzysiobal: In regard to the K-663A, I see that it's used in certain bootleg arcade machines. I do not see any datasheets for it or who produces it. If you program it with all known modes of the YM2413 does it react in the same manner? Are there any registers outside of the normal YM2413 that behave...

Re: Reminder: do not post ROM images

Why not just have a publically known onion for all NES/Famicom ROMs and NSFs without distinguishable ownership? A reliable repository of commercial material is always necessary for accurate emulation and historic preservation. The hash for the v2 or v3 onion can be changed time to time and simply ad...

Re: Mesen - NES Emulator

I dunno... It looks like there is a "click" when MMC5 low timer is set to 0x00. That seems like it's stopping generation and doing something with volume?

Ultrasonic pulse behaviors for 2a0x and MMC5.

Re: Mesen - NES Emulator

Not certain how it would have to do with the sweep register since the code is using direct writes to the timer. Mesen is emulating the behavior of the 2a0x pulses by stopping generation at >0x08 timer on both 2a0x and MMC5 pulse. MMC5 pulses do not stop generation >0x08. Dunno how emulation accuracy...
