Adapter for MAPLE (Release)

[ferreira3500]

Do you know the snes controller adapter for phillips cd-i?Can i adapt the atmega to use your project?and merge the code in one?and instead of a saturn adapter put a snes one?what is the best way to adapt to use the dreamcast controller on pc?sorry to bother you with a lot of questions,i feel that your project have a huge potencial for more things,cheers

Do you know the snes controller adapter for phillips cd-i?

no, I never had these consoles or controllers

Can i adapt the atmega to use your project?

I had to write MAPLE BUS processing in assembler, so that the ARM processor with a frequency of 72 MHz could receive data from the console
none of the cheap ATMEL processors is capable of this

and instead of a saturn adapter put a snes one?

the SNES controller has very few buttons for standard games and it is not convenient for fighting games, I see no reason to connect it to the Dreamcast
the most convenient controller for standard games is the controller from the Game Cube

what is the best way to adapt to use the dreamcast controller on pc?

the easiest way is to use a driver from a PC vibration controller
and of course, it is best to use a processor with a hardware USB, STM32F103 is perfect and it is very cheap

Man,you are great,thanks for the answers,i will see if i buy some cheap STM32F103C8T6 , and the ps2 female sockets and the sega megadrive/genesis too,cheers

[megavolt85]

and the ps2 female sockets

actually the PlayStation controller is not that good, it has a terrible DAC
I compared the original PS and PS2 controllers with the Chinese copy of the Nintendo Game Cube controller and it turned out to be better
a little later I will update the circuit and firmware, the latest version supports the NGC controller

Megavolt85, I think it is a good idea to open a donation so that we can support your projects.

On the other hand, is it possible to connect a Joystick module like this to your project ?:

Hi Megavolt85, I'm trying to make an arcade stick too with this layout, have you got a firmware version with only direct switches to ground mapping?

Thank you!

Hi Megavolt85, I'm trying to make an arcade stick too with this layout, have you got a firmware version with only direct switches to ground mapping?

at the moment there is only firmware for connecting controllers from other consoles

I will easily make a firmware for an arcade controller, but I need more information on what kind of functionality you are interested in

1) do you need VMU emulation?
2) Do you need a standard controller mode or is one arcade mode enough?
3) what is the principle of the stick? shorting four wires to ground depending on the position?

Great work this gives the Dreamcast an endless supply of controllers!

Hi megavolt85,

I love what you did with the savegames on the SPI memory, so this functionality is a big yes.
The only change will be a mapping for each pin to a switch for, UP DOWN LEFT RIGHT A B X Y Z C L R and START, no other controller conversion required, just like the old arcade machines, they use switches to ground (I think L and R buttons are converted to Z and C in the joystick photos I've seen on Internet, sorry I only have a real controller, not a DC joystick to compare).

Thank you!

Sorry for the double post, I've just confirmed from the manual:

The Dreamcast arcade stick only exposes butons: Ra (right), Da (down), Ua (up), La (left), S (start), A, B, C, X, Y, Z

Btw, have you got a Patreon? I would love to see the open Dreamcast stick for everyone.
