Dynamic switching of "virtual iQue cards" from NAND images off an SD card works :). The middle part with NAND chip is being reflashed is sped up by ca. 10x.
The first card image has some demo games (yellow square), whereas the second NAND image has only full games (red square).

Sound like itโ€™s doesnโ€™t support custom FW development.
If they only offered the M.2 module that would make sense to me. But they showed a typical ESP devkit pcb too.

We are close to the 10 year anniversary of the original ESP32 and still no real successor with Dual-BT.

Espressif sales told me:

โ€œRegarding the ESP32-E22, Iโ€™d like to clarify that it does include an I2C interface. However, please note that the E22 operates only in slave mode and is designed as a communication passthrough module that does not support secondary development.โ€

Metroid Prime 4 is basically designed like Wind Waker:
ocean -> desert
boat -> motorcycle
and the "island" gameplay is base on Metroid Prime

After 6 years working on BlueRetro, the time has come for me to move on and focus on my family and my real job.

Thank you to everyone who contributed, tested, reported issues, or supported the project over the years.
Your involvement made BlueRetro what it is today.

You need to talk with analogue it's their problem.

It's rebooting in loop, likely it's doesn't have enough power. People on Reddit look to be saying it affect only the first port? Try on to other ports?

PSA: If you pre-ordered the SW2 GC controller in May it looks like Nintendo forgot about it and let you order an extra one on the same account. (at least in the Canadian store) Received my 2nd one this week. Glad I hold off being extorted on eBay .
