Dreamcast Adapter for MAPLE (Release)

[sonik]

Wait! Dual analog in dreamcast games? I'm dreaming?

 

[darcagn]

@darcagn your console with overclock?

No, neither console I tested has been overclocked. The va0 JP Dreamcast is 100% stock, no mods.
The va1 US Dreamcast has DCHDMI/GDEMU/Noctua/DreamPi mods -- no overclock

 

[megavolt85]

No

hm, check your cable from DC to STM
analog mode stay on, it's normal
one tester have same problem, after replace DC connector all work fine

 

[darcagn]

Still no luck
Tested continuity
- from STM B8 to leftmost resistor on motherboard -- OK (see image)
- from STM B9 to second resistor on motherboard -- OK
- from STM G to ground on motherboard -- OK
- from STM 5V to 5V on motherboard -- OK
I also made sure there are no shorts to any other pins
I also tried swapping the two data pins in case I had the wrong orientation -- didn't work at all like that



I wonder if maybe my STM32 is bad?
25PE memory is not required, correct? I have not received in the mail yet, so I am making it without memory right now.

 

[megavolt85]

yep, 25PE need only for VMU emulation

you have USB-UART? i can upload software with debug

yes, few games support dual analog mode
need test more games

Yes That would be helpful

 

[megavolt85]

Yes That would be helpful

connect ground and RX to PB_6
use firmware with speed 2000000 if you have FTDI USB-UART, for another use 115200

This is output when it starts, then no more

program started
SPI ID FF FF FF
SS/MD ID = F
PSX ID = 41

 

[megavolt85]

hm, if no CRC errors that problem in PSx module
i'm write new test for you
what is controller you test? original? clone?

Official DualShock (beige SCPH-1200) and DualShock 2 (black SCPH-10010) controllers

 

[megavolt85]

SCPH-10010 A or H?

 

[sonik]

Impressive how Quake uses the second analog and even let me map all the extra buttons.
Just tested it and it`s way better to play with dual analog. Just had to adjust the "mouse" sensivity in game.

@megavolt85 I`m using another adapter. The Retropad32.
Toy Racer works fine with it. But Fighting Vipers 2 and MDK 2 wont recognize the controller.

 

[darcagn]

SCPH-10010 A or H?

Tested:

SCPH-1200 A (PS Dual Shock)
SCPH-10010 A (PS2 Dual Shock)
Gaming Edge GE1001 (3rd party analog PS2 controller)

all of them same result

Looking forward seeing your project reach completion, especially the ability of being able to use a second analoge stick as a mouse for selected games is awesome.

Any chance you will support XBOX 360 controllers as well (in cooperation with the USB wireless receiver)?

Seems doubtful as he replied earlier in the thread "STM32F103 don't have USB host, it's can work only as USB device" for USB-based controllers. The Retropad32 supports it through a separate USB module though. It would be cool, as I am much more of a fan of the Xbox controllers than PS2 controllers. They are closer to real Dreamcast controllers.

Tested:

SCPH-1200 A (PS Dual Shock)
SCPH-10010 A (PS2 Dual Shock)

ok, then need attach ACK and fix firmware

no, answer in post @darcagn

 

[spinksy]

This is awesome, watching this project closely!

@megavolt85 Is that a saturn controller socket? or the PS2 ? and a regular DB9 for Mega drive.

Great work, already bought the materials to make one for testing.

Another question @megavolt85 : I want to make a PS2/MD/ST adaptor in the same, so i was thinking in having a selector switch for the common VCC (3.3V) for each mode, what do you think of that?

for Mega drive regular DB9
saturn and playstation sockets from aliexpress

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