Questions: (Titan One) USB to Dreamcast Maple bus , or other console protocols.

Is this idea possible , or does anyone know a out of the box working solution ?

My intention is to use 7th and 8th console generation bluetooth / wireless controllers.
On (1st , 2nd) , 3rd , 4th , 5th , 6th generation consoles / Jamma , which had wired controllers.
https://en.wikipedia.org/wiki/Video_game_console
https://en.wikipedia.org/wiki/Japan_Amusement_Machinery_Manufacturers_Association

How could this be done ?
More than in one way , I think......
Cable spaghetti , converter through converter , Raspberry Pi (Zero) or similar , FPGA , ASIC.
Something like a man in the middle attack , some kind of translated , but same commands.
https://en.wikipedia.org/wiki/Konami_Code

Why should this be done?
Wireless , more ergonomic , easier to get joysticks , USB HID standardised , more joystick model choices , usable on your "old" consoles / Jamma machines.

Let's make it a team effort.
One solution for all our consoles / Jamma machines.
Can we document all console specific controller port protocols and such needed info in one thread?
Can we discuss how to find a / the solution?
Would it be possible for the skilled people , to discuss , how or what to do (chipset , hardware , source code).

I know there is a costly wireless solution for the Dreamcast

Microsoft
Microsoft Xbox 360 and Xbox One joysticks do not use a bluetooth connection.
For those joysticks there is a OEM wireless receiver.
So it would be possible to connect the joystick through the original USB wireless receiver on a USB IO.

Jamma

OK , now what ?
Into or through is >

Bluetooth / wireless or wired controller > Bluetooth USB Receiver / Xbox Wireless receiver > USB > "Titan One" ("emulated" on a Raspberry Pi (Zero) or other cheap hardware) > USB input /output bit stream >
CODE (probably the hardest part , where all the magic happens) / translation layer > Console specific joystick input / output bit stream on GPIO > Console specific joystick port cable >
Console joystick input connector.

Hopefully we have all the voltages we need for the joysticks , 5 Volt and or 3.3 Volt or lower on the GPIO's.

A Raspberry Pi (Zero) is cheap , (hard) to get and overkill , so a little bit less powerful and less features.
(HDMI , why?)



Wait a minute , full config of all joystick settings (button config) in a Raspberry Pi Zero through
HDMI on the TV , NICE.
A "full" O.S. (linux) , multiple USB Ports , enough(?) GPIO's , SDHC , HDMI , standardised.
Powerful enough to real time / low lag convert USB HID / joystick inputs to proprietary joystick protocols.
A MAME machine , AND a USB HID / joystick controller bit stream to proprietary joystick bit stream
output converter , when needed .
So we can play with our modern wireless joysticks MAME or other emulators on our HDTV's.
AND use the GPIO's to send USB HID / joystick inputs / outputs , converted to proprietary
joystick bit streams , to our "old" consoles.
Some people like me , prefer our games on original hardware , but (original) joysticks wear out so quick ,
and are harder and harder to get for a reasonable price.

A VMU / Xbox Memory card emulator on the Raspberry Pi (Zero) in linux , so enough game save space.
A TV with Picture in Picture function , fullscreen Dreamcast game , PIP VMU from Raspberry Pi HDMI output

Another nice "feature" would be to merge another project into this one for Dreamcast users.

Are there any other consoles with online features going through a modem / phone line connection ?

Raspberry Pi Zero hub
http://hackaday.com/2015/12/19/yet-another-pi-zero-usb-hub/
Why ?
4 joystick consoles , mulitap emulation , are there enough GPIO's for 4 joystick emulation at once ?
https://en.wikipedia.org/wiki/Multitap
Wow , even 2 multitaps on a PS2 ?
8 players and 8 memory cards at once ?


So it would look / work a bit like this , instead of the DB9 connector , a (few ,(4,8)) USB connector(s).
For connecting USB bluetooth receiver(s) for DualShock 3 or 4 , or the Xbox 360 / One wireless receiver(s).
Power supply connector , HDMI output.
(A phone line connector , a UTP connector optional for phone / modem > UTP option)
And all those joystick cables from / to the GPIO's.
It would be nice if we could use the original PS2 connector cables of the X-Arcade 5in1 set.

http://shop.xgaming.com/collections/adapters/products/x-arcade-playstation-3-xbox-1-adapter-2in1
These X-Arcade adapters probably translate from a
proprietary serial protocol / signal (X-Arcade) to a proprietary console joystick protocol / signal.

Bluetooth Receiver and / or USB Port for wireless and / or wired modern controllers.
"custom designed" hardware / software
Which translates USB HID / joystick inputs to console specific joystick port out / input on the GPIO's.
A power supply which is powerful enough to run a Raspberry Pi , and charge joysticks as needed.
A bit of "glue logic" , and all the other things I never thought of.

Just curious to see if anyone else is interested , in a "1 , 4 ALL solution".
