raphnet / dreamcast_usb Goto Github PK

Hi there

I am a happy owner of the Raphnet DC-USB adapter.
However, when using it with my MiSTer FPGA system (https://github.com/MiSTer-devel/Main_MiSTer/wiki) it fails to be detected on some boots, so I have to unplug the DC Arcade from the adaptor and plug it again: then it gets detected by the Linux kernel on the MiSTer.

Maybe its fixable via firmware update? However I got my Raphnet adaptor last year, and latest FW update seems to be from 2013, so I don't think there is a new build I can directly flash, is there?

I'm new to embedded electronics and I am porting this to Arduino IDE using an Arduino Micro. I have the code communicating with the controller but I am having weird issues that result in LRC errors. I am guessing it has to do with some requests having a weird gap in the middle of 6.64us.

Gap

No Gap

Going to keep looking into it! Thought I would document here. Maybe someone else is curious.

By default, when a VMU is inserted into the controller when connected to the adapter, a Raphnet logo is displayed. Is there a way of changing this default image to something else? Could such a feature be implemented into the Adapter Manager? I asked on Reddit and someone said I could build a modified firmware, but I have no idea how to build code at all...

(note: I'm not asking for full fledged VMU support for things like emulators, I just want to change the displayed image to something else like one of the static Sonic Adventure icons)

hello, I decided to replicate your device. Does the device only work with original sega controllers? in my case, a copy of the original and I have a delay of about 20 seconds. I use the board arduino pro mini atmega168pa(smd variant). please help with this question, thank you in advance
