Test the Sizif 512K with a Retro Reciever for SEGA MegaDrive crashes and locks up the system. I need to turn the machine on and off to get it back.

Is 3.3V power line stable?

I think this RF dongle maybe drawing too much power. I would buy one for tests probably.

where in the world are you located? I can order 1 and have it shipped to you. It can literally work with any BT controller. https://download.8bitdo.com/Manual/Receiver/md/MD_RR_ENG_Manual.pdf

This isn't required.

After googling a bit, I found complaints about the compatibility of 8bitdo controllers with zx-uno: https://www.zxuno.com/forum/viewtopic.php?t=3972

This may be caused by the same reason - zx uno like sizif provides only 3.3V power for gamepad.

I tried powering it through USB, it didn’t crash the system when you plug it in but crashes intermittently. It will be nice if it works, i will order the 2.4Ghz ver to try out. Thanks

Anyway, I would love to send 1 to you if you want to work on it, at least to thank you for the hard work and wonderful design.

I bought 8BitDo M30 gamepad with Megadrive Bluetooth receiver and it's works just flawlessly with Sizif-512 (rev.D). So I assume there is some issue with your hardware.

Ah, ok.. thanks for getting back.. I will test it again..

PCB rev.E released with +5 power for gamepad. This should eliminate any theoretical incompatibilities.
