Adapter for MAPLE (Release)

[RazorX]

Hey megavolt, awesome project as always, got the parts and built an adapter and it works wonderfully.

I would like to ask, there is someway that I can use the adapter just as VMU? without any controller plugged? Because i'm out of VMUs (my last one is oficially dead) and here in my country they are very very expensive. Was thinking if it was possible to make a small board and put it inside my dreamcast controllers or even the dreamcast itself, so the VMUs are always ready to be used.

Does the adapter have function show the VMUs without the controllers attached? This is the only thing I would need to make it work

Besides that, great work!!!

look back through the pages, i've made exactly that but for some reason the vmu's aren't showing up for me so i'm holding off on doing anything else right now until it's sorted.

this is my current design:

this is my current design:

Hey! Coincidentally, I was looking at your board just now and trying somethings here! Built exactly your schematic on a breadboard but the VMUs also arent showing up for me

Yet, using the original firmware with a Genesis controller (same breadboard, same STM32, same memory chip) and it works perfectly.

my board is based around the arcade stick firmware as you can see in the actual schematic i show on previous pages.
as i said i'm having issues with mine right now with the vmu's not showing up and i'm not the only one having this issue currently sadly.

if i can get the vmu's working with my board then i will release the files, i have also made a version of the board for the standard firmware with headers for saturn and ps/2.
that one currently looks like this:


i was gonna add megadrive and stuff too but i didn't have the space for the traces without making the board bigger so i may end up doing that and seeing what i end up with.

@soniccd123 if you wired yours up exactly like mine could you test it with the arcade stick firmware and see if the vmu's work if so please let me know which flash chip you used and which ST32 board you got and from where thanks.

Sorry, I forgot to say, I flashed with the Arcade Stick firmware, actually having problems even to make the controller recognized by the Dreamcast using this firmware, everything worked as expected using the normal firmware. The chip is a 25PE16VG from ST Microelectronics and the STM32 is a bluepill board that i have, the chip is a STM32F103C8T6

i know it's a STM32F103C8T6 lol because that's what's required, i was looking for something more specific
also how is your 25PE16 wired up? because you connect it to different pins for the arcade stick firmware, it's not the same as the normal firmware pinout.

I'm sorry, let me send you the full text of the STM32 chip:

STM32
F103C8T6
991HL 9U
MYS 318

But I don't think this change much, I've worked actually in some professional projects that use this MCU (mostly in the project own PCB, but used the bluepill for easy prototyping from time to time) and never saw a variation of this chip specifically, there is the STM32F103C8TB, but it is mostly compatible with the bluepill one.

For the Memory chip, I've wired as your schematics when trying the arcade stick firmware, for the stock firmware, I've wired it as showed in the first page.

then yeah it must be an issue with the arcade stick firmware then if you're saying the vmu's work for you with that board on the normal firmware but not the arcade stick firmware, hopefully megavolt85 can look into this.

Arcade Stick and Twin Stick firmware updated, fix for VMU

P.S. I have an STM32 on which VMU emulation does not work on the main firmware, I tested and with this firmware, saving works even in such a demanding game as 4x4 EVO
