Possible TX clone chips, Apple vs. Epic trial, and more! - Tempcast #38

tempcast 169 logo.png

This week, we're running a skeleton crew with only Ericzander and Stephen on hand to discuss this week's topics such as the appearance of possible SX OS clone chips, Sony's partnership with Discord, and the possibility of a lawsuit targeting Sony's control of its digital marketplace. We also discuss several big revelations that have come out of the ongoing Epic vs. Apple trial.

Funny enough the Gameboy could have up to 8 mb and there is s game that's supposed to be even bigger than that.

Technically speaking there's no limit



They were basically floppy disks, the disk system that could have played big music files is the doomed to fail Nintendo 64DD.

With a bit of compression, you could probably stream digitized audio with a fds, I'd use an fdsstick anyway, fds was more successful than 64dd

Not on a Nes, the hardware is not powerful enough to handle any sound decompression at all, so the only option is degraded audio quality and even then is gonna take more that two MB to store a full tempcast episode.

Again all You need is a memory mapper, you want a 1 terabyte Gameboy cartridge, all you need is a memory mapper (memory management unit), the Gameboy without a memory mapper only allows 32k of rom (the memory mapper swaps portion of the 32k rom to allow more memory, bank switching)I simply use flash memory instead of a read only mask rom, the cartridge is functionally identical to any Gameboy cartridge

The hardware was built with expandability and the usage of memory mappers/co-processors in mind, that's why the nes has an unused expansion port, that's where the fds would be connected, though I think piracy is why it didn't get released outside of Japan, you could hook up a fds floppy drive to a commodore 64 or Atari computer, copy disks pretty easy

They are literally a cheap 1980s home computer

And I'd say some basic compression is possible, it's 7 bit pcm audio you could fit the temp cast at that quality in under 10megs, add some on board ram on the cartridge

--------------------- MERGED ---------------------------



This is dpcm uses less memory than pcm, but you can hear the difference

The quality is crap.

I have listened to audio from AM radio programs that are like eighty years old that sounds better than that.



Anyway, you keep saying "streaming", why the hell would you stream audio from a computer to the Nes?

Learn some programming and you'll understand what "streaming" data means,

Too much YouTube it seems, same concept different implementation

And it's digital audio playback from 1983 computer hardware, you can use pulse code modulation for higher quality, but uses more storage, delta pulse code modulation use less storage but quality is degraded

I didn't say it was going to be 96khz sample rate quality audio

--------------------- MERGED ---------------------------

Wrong, it's 2021, memory is cheap nowadays, that's the only real limitation, but we have flash cartridges

And the famicom disk system has an extra sound coprocessor (fm/wavetable synth, similar to the Gameboy wave channel, but more features)




7bit Pcm, better quality, I believe Pcm on nes can reach near 31khz sample rate iirc

Nes is technically similar to the Atari 8bit line

That's not exactly a secret, that's why the Nes had so many ports from the Atari early on. And why fans have ported simple Nes games to the Atari, like the Mappy port.

Coding however is not exactly the same.

It isn't exactly the same, but the architecture is heavily based on the Atari 5200/8bit computer, just a bit simplified

The ppu is an analog of the antic and gtia, effectively combined in one chip, the 2a03 combines the 6502 and pokey ( controller and audio)

The ppu can dma memory, and draws using tiles and not scanlines

The "display list" is stored in rom or ram, instead of using the CPU to generate it like in the atari

They also have their own dedicated ram 2KB each 4K total, also unlike the Atari, the nes design allows easy expansion of the hardware, the entire ppu and CPU busses are accessible via the cartridge port, you need more ram, you just put it on the cartridge with a mapper, same with a SD or CF card, add a microcontroller to use as a co processor or use an fpga and create your own nes "super fx" chip


It's different enough so Nintendo can have their own patents on it

You do know patent law in the USA is insane right?

So that really doesn't say much.

Yeah, on November 22, 2025

You will be able to clone the xbox 360 hardware, same as they do with nes clones, on November 11, 2026 you can do that with the PS3

Hardware patents are good for 20 years

Not saying you'll have xbox360 and PS3 on a chip, but you can build a computer that will run the software, and sell it (blank, end user configurable)


Software/code is 75 years

I was pointing there is a reason the USA has the most patent trolls of any country.

Copyright trolls

Patents are for physical hardware

Copyright is for software and code

Both are covered under intellectual property law and dmca

In the end the patent and copyright owner can do what they want with it, it's their legal right

Copyright trolls can get into trouble too,
