Paprium cartridge PCB and hardware

Post by olddb »

As you may know, the Mega Drive game Paprium was finally released.

Here's a look at the PCB. I'm curious what nesdev has to say about it.

Edit: Can a mod fix the title?

Hard to say anything useful without a better picture of what all those 13 parts are under the "heatspreader" (narcissism)

But ... if I was gonna make a guess, I'd suppose that the 9 identical-looking small parts are voltage translation, and the long part is a 128mebibit (16MiB) flash. Programmable logic and RAM, maybe. I'm confused by the headphone jack.

I talked with people that worked on the project and the headphone jack is some kind of device for very crude network communication. This was designed around 2013~2015 when thinking to put wifi in a cart was not common. There is good chance it will be used to update some stuff in the game but since the game has just been released, this as not been announced yet.

Just for comparison. I think it is the solution of flash cart

As for the headphone jack, I think it's an USB port.

The manual has pics of the modem part, it's just an ESP connecting via an audio cable to the jack. There's mention of 1.2kbps bw for the audio jack.

Due to long delivery delay and compatibility problems (unable to run on most models after genesis model 1 va4???Uncertain, just my guess), original developers have started to sell assets. It's a sad ending.

I think the real key is not the negative emotions of some fans on the Internet, but the hardware design. Although it is a good game, but the physical carrier is too bloated, which leads to high cost, while the compatibility of core functions is on the contrary

Aw, that's particularly tragic.

Old news? They announced selling assets months ago.
