ESP32-WROOM-32 and NeoGeo AES internal connection

[UnrealEditor1]

Hi,

I'm wondering if I can connect the ESP to the NeoGeo AES just without cable... technically straight at the controler output of the mainbiard.

I aslo have a big problem with the "cable building instruction". The pictures of the "BlueRetro LS 1.1" are different from the ESP32-WROOM-32. I don't understand how to connect it to the ESP because pinout description is different. Is there something I'm missing?

Regards

Only look at the DIY Through-hole section:
https://github.com/darthcloud/BlueRetro/wiki/BlueRetro-Cables-Build-Instructions#diy-through-hole

You got the pdf schematic there, for internal install just ignore the DB25 and wire to ESP32 base on net name. You need the level shifter chips. ESP32 is 3.3v and NeoGeo is 5V.

Its all fine

Would you mind helping me on the wiring diagram? Just for the ESP and the level shifter? Really don't want to destroy my NeoGeo AES. I can also pay you for this.

If you don't have the confidence to do this mod, don't do it.

Pay someone to do it. You will have find that someone yourself, I don't have any contacts for this.

And I'm not doing mod myself, I too busy with real family life.

Again I'm very sorry but can't help more than what the repo & wiki contain already.

Hey there,

okay, no problem! Thanks for being honest and all the help so far! :)

Hey DarthCloud,

thanks for taking your time! I'm very new to this and I try to do my best.

Is this correct? https://ibb.co/ZY0zzxK

I'm really not sure about the GND and Vcc part... I probably mess that up :(

WARNING! The connections in your is scheme are 99% OK but the correct IO3 port on WROOM PCB is the RXD
DO NOT CONNECT ON SD3... I had Haomaru always jumping.

hello
I received my level shifter and I start in the Neo geo.
I saw the diagram above and was wondering if the esp32 needed a power supply ?
Nothing is plugged into the 3.3v or 5v of the esp32?

As a said earlier this schematic got all the info you need:
https://github.com/darthcloud/BlueRetroHW/blob/master/DIY/Para1P_OD.pdf

Ignore the DB25 and just connect things to the matching label name.

Here where I am :

I've only plugged in button A so far.
It still does not work.
Should i plug all buttons ?

PS: It works flawlessly on my DC!

Got it !!!
I just need to learn to count correctly... I reversed the row from 8 to 14 on the 74AHCT125N...

[UnrealEditor1]

can you please make a diagram or good picture of the wireing?

Hey there,Don’t use the diagram. I tried to find a question for same answer but nobody replied. All I know is you have to use 3x level switch which you can see in lower right corner but I don’t know how to connect level switch to esp. all I know is that you take power from Controller port to level switch…. Hope that somebody can continue or maybe change my diagram to finish it. Gesendet mit der mobilen Mail AppAm 02.03.22 um 10:51 schrieb pkerga Von: "pkerga" ***@***.***>Datum: 2.

When you order the PCBs they will come like this:

This is what they look like Assembled (The BOM is in Github, basically the same as @darthcloud's Part Lists on the cables page. )

You are see the Main PCB, Gamecube, 3DO and PCEngine.

I am also working on a PCB with a alternative to the DB25 connector, I looking into a keyed cartridge slot, think something similar to the NES or Genesis Cart/Plug.

Cool stuff I'll add to the community links on main page.

Thanks! I need to button up the comments and stuff!
