Dreamcast Adapter for MAPLE (Release)

[toze3]

for Mega drive regular DB9
saturn and playstation sockets from aliexpress

I just asked because I saw this socket without cable for PS2, and also others, but not for Saturn

bad idea, for example, saturn controller fine work without VCC (he get power over internal pull up resistors)

So there is no problem in having the 3 option there, just not connected at same time. OK

By the way nice printed case.

Thanks and great job

I wonder if maybe my STM32 is bad?

it turned out that my chip is cs32f103c8t6 with rewritten marking
oddly enough, but my clone works faster than the original
now i have original stm32f103c8t6 and i can fix errors

Awesome, good to know that's probably why I didn't have luck with mine.
Funny, I looked hard for a genuine one because I wanted to make sure I didn't run into a compatibility issue.
Looking forward to an update! Thanks megavolt!

I just see this mod for keyboard :
it uses your system ? @megavolt85 :

A custom Dreamcast keyboard

I bought a custom mechanical keyboard from WASD Keyboards to use with my Dreamcast.

no, this mod use "total control 5" and special keyboard

total control cannot light CAPS, NUM and SCROLL LOCK bulbs, so the author of the mod bought a special keyboard that lights these bulbs by itself
as far as I remember, people complained that the tilde button does not work when using total control

Thanks man, it's working perfectly with the mega drive controller

@FamilyGuy
right stick work as mouse in both games
may be developers don't test this functional, wrote relying on the SDK

Hey, I just signed up, been a while since I logged on at assembler...

Mad Catz Panther DC is the controller on Dreamcast that had dual analog. Trackball for left hand and joystick for right. Had a mode switch that disabled the trackball for compatibility with regular games. I have one so this is how I know.

Could your project here be used to enable analog in any game given some sniffing?

Use a debugger / cheat engine to find address of camera variables (if stable / static location) then inject adjustments to the camera angle based on mouse or 2nd analog stick from a controller.

Not sure if you have access to RAM through the MAPLE Bus?

all devices on the MAPLE bus are slaves, they do not have access to RAM

Someone with the adapter could test if a ps1 guncon would work?
It might just work as an analog controller as said in this post:

My Guncon 1 works in Windows without any custom drivers...

Hi @megavolt85

i have made from a generic oem Wii-PS2 adaptor a mapple DC->PS2/ST adaptor and works great. Now I was checking to add also de MD and saw the difference is the PIN 6 of both controllers (TL) that in ST version is not connnected and the MD is connected to PB_14. So my question is, can i connected the pin 6 of the saturn to PB_14 and still get the things working? My idea is to make from the other ST male plug an adaptor ST->MD (bought an extension ST cable, and used only the female plug).

Or should i dismantle the old one and make a PS2/MD output, and from here an adaptor MD->ST?

 

[megavolt85]

@toze3 pin 6 (TL) in the Saturn controller is connected to VCC, I do not recommend connect supplying power directly to the digital port of the microcontroller

Thanks. I will then try to change my adaptor

how do i transfer how to copy firmware to stm32 ?

you can use ST-LINK V2




or USB-UART

Hey @megavolt85 I was testing an 8bitdo M30 wireless on an arduino and to my surprise the 2 extra buttons are reported on the DB9 dongle!
The bits are on the last read when handling it as a 6 button controller.
The bits are: [ Start, A, 1, Star, 1, Home ]
On a normal pad is: [ Start, A, 1, 1, 1, 1]

You can add two new buttons to your adapter
Or atleast one. The Home button.
As the Star button is used to enable turbo mode.

nice work man, are you eventually going to release the source code? I would love to modify it for the portabelizing community.
