USB4MAPLE adapter

Thanks megavolt. I think I have the Chinese extension cord then . Can you tell me where the other cables need to be if they’re not correct?

Hi!

I’m curious if it’s possible to integrate an internal VMU into this project and share it with BlueRetro. BlueRetro’s VMU management is currently quite buggy, and it lacks support for the VMU screen.

Key Questions:

Is there a way for both projects (this one and BlueRetro) to work together on the same Dreamcast port?

Could the usb4maple project potentially include a port passthrough feature? For example, the input would be a Dreamcast port, and the output would also be a Dreamcast port. This would allow the pad to be managed while keeping the VMU functionality on the maple side.

Testing Observations:

I tested an internal BlueRetro setup with a Bluetooth pad on "Port 1." When I connected a real Dreamcast pad with a VMU, the VMU was disabled.

I also tried removing the VMU from BlueRetro and disconnecting the alternative pad, but the real VMU remained disabled.

I suspect this issue occurs because BlueRetro and real gamepad are trying to use the same port simultaneously.

Proposed Solution:
If usb4maple could support a passthrough feature, it might allow the pad to be managed while the VMU functionality is handled separately. This could potentially resolve the conflict and improve VMU management.

Looking forward to your thoughts!

I assumed it was a lack of GDEmu that was making things weird, but you have one from the look of it and are facing a similar problem.

This is true. I am using a GDEmu. ¯\_(ツ)_/¯ It normally doesn't cause issues and I tend to just be able to delete the extra saves with botched extensions later on. plus it only happens sometimes.

no, don't possible.

try this update

added:
HoriPad 3 turbo (VID = 0F0D PID = 0009)
Thrustmaster eSwap Pro (VID = 044F PID = D00E)

fixed:
restore VMU from last.cfg

rumble underconstruction, few effects can don't work, few work better as in original rumblepack

I'm using this build. I can get my PS5 controller working fine, but my Hori HRAP-4-Kai does not function at all, in any mode, PC/PS4/PS3.
