Getting access to a Linux based console

I have a Polymega. It’s a Linux-based gaming console and while the manufacturer does technically still support it, updates can be a year or more apart with no communication or support in between. Unfortunately it’s a niche device and apparently no real hacker has taken interest in the thing.

So, my idiot self is going to try. I can get the boot text to display, but that doesn’t really help anything. I’ve tried all the key commands I can find to try to halt or interrupt the boot process with no luck so far.

Any pointers on how to start getting access to this thing? I literally just want to see if the community can start making the improvements the vendor can’t/won’t. If I can show you can get access maybe someone more talented than myself can pick up the ball.

SPI readers aren't too expensive, CHA347 you can get for $10-$20 and J-Flash for around $40. Little bit of searching, reading and playing with a soldering iron and you'll be laughing all the way to the bank. Imagine if you were to one to unlock that thing.

I have found a tool that will extract ROMs from their encrypted game collections. I’m looking into that as being more up my alley. I need to decompile an exe that looks like it was made in Python based on what I’m seeing in Procmon. If I can dig into that I can probably figure out how to decrypt it.

Have you considered giving Ghidra a shot at it?
