FYI, RetroArch/Libretro devs are working on similar game adapter as open source hardware

[Hedda]

RetroArch/Libretro developers have announced that they are working on a similar adapter which will become open-source hardware:

"ProjectFuture" goals sound to be high-speed so could potentially be used for playing games directly from a game cartridge(?).

From the picture posted, it looks to be based on an STMicroelectronics "STM32 F7" which is a 32-bit ARM Cortex-M7 microcontroller(?)

If so then I am guessing it is the STM32F767ZI (STM32F7 MCU) and developers prototype using NUCLEO-F767ZI dev board

STMicro STM32 Nucleo Boards with STM32 MCUs can ex. be used with ST STM32 ( STSTM32) development platform for PlatformIO:

PS: Cost per STM32F767ZI as SMC looks to cost between $12 to $17 when bought in small quantities to only build your own DYI board.

This looks very promising, m4xw is a great developer. Thanks for posting.
