Hello everyone.
This is my first post here. Like all of you, I am a virtual boy enthusiast, and as you all know nowadays it is difficult to get a flashcart, especially for me living in Europe (The VB never arrived in Europe). That’s why I have decided to design my own flashcart thinking to make it as cost effective as possible and also, to share with you the plans and instructions so that everyone can build it, because customs increase the costs and shipping is expensive between countries.

STATUS: (28/03/2024 updated)
Working in a new version with problems solved and more features

SPECIFICATIONS
I hope:
32Mbit Flash
Games stored in the uSD
Save games in the uSD

PC SOFTWARE
For the tests I am using the freeware RealTerm

DESIGN:
uC: STM32F103VET6
Flash: 29LV320

Why STM32F103VET6, it is a cost effective uC ARM based at 72Mhz with a very cheap development board, it has enough pins to be used as “Paralell 16bits Flash memory Programmer” using a common Serial port at full speed as input.

The STM32 and Flash work with 3.3v, so i need some level adapters like TSX0108 for 3.3s <-> 5v with VB

Hello!
I’m also going to assemble my own flash cartridge. I am desperately looking for information on schematics and open information on creating such virtual boy cartridges. Can you share such information? Where to begin?
