I managed to get VMU support working great! I plan on adding a screen tomorrow when it comes in from Amazon.


I've got the RP2040zero plugged into an Adafruit (5999) CH334F 2-Port USB Hub Breakout. Then I have my PS5 controller plugged into USB 1, and my USB drive plugged into USB 2.

I have noticed several quirks with this though. If I reverse the controller and the USB drive ports, from 1 and 2, to 2 and 1 respectively... the controller will eventually start lagging after a few minutes. As long as the controller is plugged into port 1, this never happens.

The other quirk, is that even though I have a 16GB flash drive plugged in, you still only have 200 blocks of memory on the VMU.

And then of course, the Hori RAP4 Kai not working is something that will hopefully get fixed in the future.

Are you using openmenu with a GDEMU?

With this setup a separate VMU will be loaded for every game you play.

I'm using a stock Dreamcast.

there is no point, without GDEMU or DreamShell the images will not switch, only vmu.bin will always be used

OK. Even if you create a vmu bin with the correct gameid? I guess you could backup & delete the current vmu.bin and start a new one.

who will give the command to usb4maple to do this?

Nobody. I was thinking of manually managing the flash drive with a pc. Of course, this can already be done without the new utility, but it's nice to have a management utility.

Would an SSD1309 work with this? Or is the SSD1306 the largest screen?

I found information that SSD1306 and SSD1309 have the same set of commands, if you have this display, you can try to connect it
