Btw did anybody get anything to test from SuperBenoit?

Even just modifying the Menu button to just L or Select&Start on the existing SMSAdvance/Goomba would be a massive help.

Something interesting on JZ4725B:

What is this for and what does it do exactly?  Any idea?

Using jzboot you can dump and flash NAND of devices with jz4725b.
Vogue player (https://geektimes.ru/post/256610/) has the same processor but different NAND chip.
I managed to dump some data but jzboot throws error like

Ingenic: ECC failure while reading NAND. See UART output for details

Is there any way to make it work with the different nand?  or someone with technical/programming expertise will have to help?

The first link is for documentation and code for the JZ4725B SoC in the Retro Mini. The second link is for a hack that someone did using similar hardware to the Retro Mini. Looks like a custom formware to be honest.

Indeed. While I got the PMPIV now which for some systems provides much better emulation and screen resolution, the build quality and the feel is nowhere near the retro mini.

 ;D lots of hints being dropped here! Unfortunately no takers so far! Personally I'd merely like to delete all the roms that came with it.

Difference between JZ4760 and JZ4760B: LINK

Additional infos:

The Jz4760B is mostly an hardware improvement on the Jz4760 with smaller die, better power supply, controllable I/O drive strength, OTP unit and internal buses improvements. The IngenicJz4760B is pin to pin compatible with the Jz4760 except for a slight tweak needed for OTP (if used).
