Very nice sir!

My only comment is you probably want to use translators instead of just inline resistors. There’s a reason most of the flash carts use the 245 translators chips and they’re only a couple dollars each. The concern is on the STM32 side. The VB input should work at 3.3V logic.

And if you haven’t already, you’ll want to sign up for the Discord channel. Most activity is there these days.

Another hardware developer in town. Nice project and progress! Don’t let anything stop you.

Let everyone know how the Red Alarm Repro holds up; I try to make our stuff indestructible. Also, nice get more positive visibly on our repro work.

If need any free/sample connectors to help just let us know.

Interesting project.
How far evolved is it? Do you already sell working flashcarts?

[mellott124]

Beware those TXS0108 translators. They don’t like bus capacitance and won’t work well between a flash cart and the VB. You’ll have no end of problems. They’re meant as bidirectional translators for on board chip to chip applications, not for signals that go off board.
