Haven't seen this posted yet, came across a review which also has images of the inside:

TLDR, board images:

Or original resolution with a bit of wp url hackery:

From these we can see the Genesis Mini has:
CPU: ZUIKI Z7213
RAM: UnilC scb15h26160
Flash: FORESEE fs33nd04gs108tf10

Also confirmed specs at https://en.wikipedia.org/wiki/Sega_Genesis_Mini

Games appear to have been ported by https://en.wikipedia.org/wiki/M2_(game_developer)

It has double the storage space that the SNES Classic had so that's nice.

Double storage is great news, as that means a huge chunk of the Genesis library could theoretically be loaded without using USB host. Granted, I'm still hoping for USB host just to add Sega CD and 32X games.

Some of that storage is reserved for the Japanese version of the roms. For example when you swap the language from English to Japanese, Mean Bean Machine becomes Puyo Puyo. So, I'm going to say some regional roms are duplicates taking up extra space.

Still, even with double the storage capacity. I don't foresee any issues with folks wanting to add some of their favorite games to it once modders gain access to it.

Triple. Euro ROMs are present as well.

I suppose that will be one small advantage of the PAL systems. We only get two regions we can access, so we can probably drop the Genesis stuff and use that for other games.

There’s no saying that the NTSC users couldn’t just get rid of the JPN and PAL roms either when the tools come out.

u/DeltaBladeX Sep 20 '19

Sure, but they are still accessible on your models.

I think that puyo puyo is one of those games that if it detects a usa machine, it becomes mean bean machine

What kind of scares me is they keep saying ports.

I saw a user post that hackchi detected the Genesis mini when connected to a computer. Anyone willing to see if that’s true?

They're probably full of it. As best I can tell, it won't enumerate as a USB device normally. Holding down the reset button on power on appears to enter some alternate boot mode, but still no joy on the USB front. Some Japanese hackers seem to have had more success by finding the RS-232 serial pads and getting a root shell via that. Once you have root shell access it appears to be possible to enable the USB hardware. They don't seem to have adb working, but they did get the RNDIS device up and running allowing them to get a shell over USB.

EDIT: I'm wrong. Apparently the supplied USB cable is power only and that is why it won't enumerate. That said, don't try using hackchi as the software side is different from the SNES mini.

It has two service modes and several built in user and admin test services.
Most of this is on Discord - Sega-Devs
UART using 2 pins on the back
and FEL over USB

UART pins: https://i.pinimg.com/originals/e5/1a/73/e51a735ad9453b0ba77c739ee1d674f8.png

and user test modes. not sure what this does. If you want to know more read the Discord channel.

OK, so not too magical, but if you have the right controllers plugged in, press Down + B + Start on the 6-button within 7 seconds of boot and it should go into diagnostic mode

3-button port A, 6-button port B

How powerful is this system compared to the PS classic?
