2023 repro MVS carts

[Bigblue709]

I have a few of these and one of them crashes out fairly early into gameplay. Opened it up and the circuitry looks fairly simple. It’s beyond my skill level, but does anyone know if it would be possible to reflash / reprogram these carts?

What were you hopping to flash onto it? Based on the chips I see, this probably has 1 or a dozen games on it at the most. It doesn't have the capacity to hold anything beyond that. So it's pretty much good only for what it's doing now.

The other thing I find interesting is the date codes on the 2 PCBs. Has China ran out of parts?? There's 4 year difference between the 2 circuit boards!

It’s a single-game cart (Shock Troopers), I’d be okay with any playable game on it really. The seller sent me a replacement, so this one is available for tinkering — but I’m not sure where to start

Are you able to share the back of the PRG board? It's the back of the first image that has a PCM2 chip on it. Would like to see what they used for P and V flash ... Take a full image of the entire cart, including edge connector.
