Super Mario Bros NES With N64 Samples 7-BIT PCM Mode

- Ever wonder what Super Mario Bros was like if the samples from Super Mario 64 were inserted (using the NES 7-BIT PCM mode)? Actually, the samples are quite clear though you can tell there is a very small amount of loss of quality due to the interrupt timer having to cut down on samples being pushed tot he NES in order for the game logic to run. slowdown was removed as much as possible and looking at the modified code, it is very impressive. (NO, I DIDN'T MAKE THIS MODIFICATION, MUCH TO YOUR SURPRISE: HERE www.romhacking.... - Although I could have to be honest.) - I don't usually show other people's work, but I was very surprised and impressed when I saw it earlier.

Super Mario Advance 5 looking great
YES I DID MAKE THIS MODIFICATION, MUCH TO YOUR SURPRISE:
when Mario speaks, the game has a small slow down
*NES limitations*
0/10 Mario doesn't say 'just what i needed' when he gets a 1up
Nintendo,
HIRE THIS PERSON
"that's just what i needed"

How big is the final patched ROM?
264 KB (270.352 bytes)
The original Super Mario Bros. ROM is 40KB (40.976 bytes)
@@52298datoyo Wow, that's tiny.
Oh, I expected the music to be made of samples too.
That would not be possible unless you want the game to run at 2-4 frames per second.
Wow, compare this to the attempted Pikachu voice in Pokemon Yellow and it's just night and day. Karmic did a great job with this.
No
the gameboy didn't have a pcm channel though
the gameboy didn't have a pcm channel. the pikachu voice was wavetable abuse.
I must be dreaming...
Nope.
Damn, Didn't Even Know You Could Play 7-Bit PCM And Make The Gameplay Nearly The Same Speed Too.
Quality is noticeably reduced in this implementation, it is still possible to get perfect quality, or as much as possible if more of the IRQ timer was dedicated to the samples with reduced gameplay speed.
@@nensondubois Yepe!
There's still some 60 Hz crackling. It seems like the IRQ timing isn't quite smooth.
Glad someone noticed. The timing had to be balanced with the game logic without slowing the game down to a crawl.
@@nensonduboisBut with a proper IRQ timer in the cartridge that should be a non issue, as the cartridge does the timing and the CPU just responds to the interrupt.
It definitely wasn't possible.
@@nensondubois Why so?
Super Mario Advance 5??? 2021????????
What have you done? You gave Mario a Gexually Transmitted Disease!
What's PCM
Pulse Code Modulation, basically, a way of storing sound wich involves taking the height of the sound wave at many different points in time. The nes was cappable of outputting 7 bit PCM sound, but it uses lots of memory and cpu, so it was seldom used.
@@mazionach if samples came from a digital music or a PCM sound chip, do they take a lot of storage space
Pulse code modulation, storing sound samples e.g the bang bong drum sound in SMB3 in the 1-1 theme.
1-Bit DPCM my beloved. ❤
( Yes i know it isnt DPCM because of the few slowdowns, specially with the "boing" sample )
1-BIT DPCM was the most common method for sample playback from the NES. 7-BIT was rarely used because it requires a lot of resources in both limited ROM space and processing memory, and it wasn't feasible without interrupting or slowing down the game logic for both to play simultaneously.
@@nensondubois yes thats what i said in the parenthesis, but still thank you
cool mario
Heheheheheh AMAZING

Do we really f@ckin care about that? (joke jk xd I care a lot)
What a stupid comment.
