Jokes on them, haven't given a single one!

Very nice shitpost OP, very nice.

Ah ça, c'est drôlement intéressant !

Je pourrais attendre qqs mois pour changer, si c'est pour un beau projet, y'a pas de raison.

EDIT: par contre, je comprends qu'ils ne feront que les .fr dans un premier temps, j'ai essentiellement pas ça (.be et .social).

Aucune idée ! Là pour l’instant on me dit entre 7 et 8€ par transfert de toutes manières.

Sont pas Suisse ? Oui, j’ai oublié de précisé, mais je préfèrerai un registrar 🇫🇷

(après en vrai, faut que je regarde)

:pikachusurpris:

Not far right, just right. But yeah unfortunately not a surprise.

I managed to do that (not an easy fit but I think I’ve achieved the measurement properly) and you’re right: the cable itself it probably of very poor quality. Given that Blueretro is mostly a DIY project I think I’ll make the cable adapter myself instead of trying to fix what is obviously not fixable.

Thanks for the help!

Only Blueretro is affected. Maybe the Blueretro NES adapter cable has just poor quality components. The other cable adapters I have for other consoles work fine, including the SNES which also operates in 5V.

It should be possible to power the BlueRetro using the controller port only. IIRC, the controller pins providing power are directly connected to the internal NES regulator, so with enough headroom to spare, you should be good to go. Eventually, this will depend on the firmware of the ESP-WROOM module used by the BlueRetro (max. current draw for the ESP32 should be around 250mA with all peripherals enabled and transmitting, I’d expect the BlueRetro to use quite a bit less in normal operation). That’s also what the 8BitDo is doing, running at around 100mA.

That’s what I thought too. I originally ordered 4 cables (NES, SNES, N64 & GC). I only had troubles with the NES so I decided to just get a replacement. But the replacement has the exact same behaviour, so this is either an issue with my NES or the cable is not designed properly for PAL NES.

Where did you get the level shifter cable from?

What do you mean by that? The cable itself? It’s from Aliexpress.

I’d also like to know the results of your voltage measurement in operation

As stated below:

• 4.8V on the controller port itself
• 4.6V inside the cable adapter without Blueretro Core attached
• 3.9V inside the cable adapter with Blueretro Core attached
• 3.53V on input, 2.61V on the output of the AMS1117 when powered by the console only (and the Core itself is not functional that way)

If push comes to shove and you decide to replace the LDO, the TLV1117LV made by TI would be a potential candidate, should be a drop-in replacement with better specs (price is about $0.30)

Will it change something when the input power is so low? I feel like I might as well connect the 5V rail directly to the 3.3V input on the Blueretro…

The 74AHCT125N appears to be a 3v to 5v level shifter

I don’t think the cable adapter is using this particular chip. I see two much smaller ones. Maybe that’s the issue.

To be abundantly clear, is the Blueretro meant to work when only powered by the console? It certainly wouldn’t be as convenient – an extra cable and power block to deal with – but everything is functional when externally powered by USB, yes?

That’s right Blueretro is supposed to be powered by the console alone. When powerd by USB, it is perfectly functional.

Do I understand that your original post is debugging why the console isn’t sufficient to power the Blueretro?

That’s correct.

I can respond to at least your second question right now: I can power the Blueretro from USB while on the console that's how I know it is functioning properly when powered properly (my original post wasn't clear enough I guess).

I'll test the voltage while powered on as soon as I can.
