ok, i'm test it, thanks for report

Could you add Ikaruga to the analog stick support list?

do you mean the analogue control patch like for Dino Crisis?

I think I found a bug with VMU emulation and Maximum Pool. The game won't boot (black screen) if a flash drive is plugged in. If the flash drive is removed, the game boots up fine. Can anyone else confirm this?

Hey @megavolt85, would it be possible to add one of these usb A female ports to the pi pico? I have seen some people adding usb C ports to the test pads on the back of the pi pico boards. I ordered a 4 pack of dreamcast extension cables to cut up for this project to prevent hacking up a dreamcast controller.

Are their any plans at all to implement a standalone VMU instead of needing to use a controller in tandem to have it work? I use an Xbox One controller wirelessly (which I believe cannot be setup using this adaptor), so it would be beneficial for me to keep the controller I currently have and have a VMU emulated. Thanks.

This version also fixed a problem on Sega Rally 2 when saving.

I already answered in discord, but I’ll duplicate it here in case someone wants to do the same.
Yes, you can solder an external USB-A to the control points, the main thing is to disconnect all devices from USB-A at the time of flashing

no, I don't plan to make this possible, but you can connect a keyboard or mouse to the adapter and then the VMU will work

UPDATE - DO NOT FOLLOW DIAGRAM, SOFTWARE USB IS NOT SUPPORTED:

Hey friends, does this wiring look correct to add a USB A to the Pico Zero?

no, it won't work that way
usb connects to gp0, gp1 only when using software usb and I am using hardware usb so you need usb otg

Hey friends, does this wiring look correct to add a USB A to the Pico Zero?

Also, is it worth adding a Schottky Diode (1N5817) somewhere, perhaps between the Pico and the USB-A VCC line? Thanks for any help

@Megavolt Can you upload the Waveshare Zero version with the new fixes? I got a couple Zeros that don't work with the regular firmware. It seems random because it's out of a pack of them. Maybe 1/8 need the special firmware.

Also, is there any way you can make one firmware that works with both? That way people don't need to guess which one they have?
