Prototype K5L dumper and G5 Handheld

A project log for Dissecting a hand-held NOAC console (Sup 400-in-1)

This is an attempt to understand how these little things work, and what we can do on it.

This is two topics, but I rather squeeze it into one here today.

I also recently got myself those "G5" Handhelds - they were sold for $3 at a certain time of the day and month, so I got myself these too.

Instead of the casual "400-in-1", I got a "500-in-1" too. The games are mostly identical to the "400-in-1" and they are still mostly filled with mediocre games inside.

So I ripped it out and yes, it's that usual BGA Flash Breakout again:

As usual, took this flash out using "ChipQuik" and did the dumping using my K5L dumping tool there in my github.

Unfortunately, this dumping isn't any smooth or easy. I kept getting broken tiles and sprites inside, or corrupted binary. There are really loose wires and such all on that breadboard (and it's caked with some dust!) Didn't even use it for a few more months, and there goes all the connections! Breadboarding is only good if I'm testing the prototype, but as it's now working, I should be putting this onto a board instead.

Fortunately, I know there's this service called PCBWay to help people to build more effective tools in a low cost and reliable way. Then I immediately drew this, and sending this one to the PCBWay over the weekend!

After messing around with the connections again, I got that bin file dumped in a more consistent manner. Examined it and this belongs to the next log! :D
