My Rpi3B is a little unstable, thinking of buying a cheap ST-Link V2, can anyone recommend one?
No, they are rubbish! Doesn't work because they don't have a hardware reset as it is needed. There is a stlink_v2_clone_hardware_reset_patch_v4 around but i didn't got this piece of sh... to work. Better buy the real Nucleo-64. I bought the cheapest version for 17 € in Germany.

I can't believe that my problem's solution is so stupid!

now everythings works fine.

Now my only problem is that I thought the G&W roms was smaller. It's impossible to play with all roms without increase the memory.
Did you manage to install a bigger memory chip?

Hello all. I have finally decided to buckle down and mod my Mario G&W. I had previously ordered a STM32 (STM32F103 Nucleo-64 to be exact) for doing the flash mod and an upgraded 128Mbit flash chip (MX25U12835FM2I-10G) . I notice a bunch has changed since then (no patch needed for larger storage chips) and for some reason can no longer find a guide on how to do everything that isn't specifically for a raspberry pi.

Can anyone link me to a current guide for doing the mod with a STM32 please?

EDIT: Got as far as running the backup and restore scripts so my G&W is unlocked but stock right now. Looking for steps to both install retro-go and games as well as when during the process I should replace the flash chip with my new one.

Thanks in advance.

Guys, modding these seems to be really tedious.

I just want to run the factory OS and just add super mario bros 2 and super mario bros 3 to make it the ultimate edition.

Has this not been done yet? Surely someone can compile it :D

Can this not be done with the 1mb of storage?

Looking through some of the recent script updates, it appears that the Zelda GW has a 4mb chip where as the Mario one has a 1mb chip.

Not a huge difference, but will allow users who don't upgrade the chip to get a little more space.


Been out of the loop with the g&w modding scene.

However your internal stlink install is something I would prefer, was there any guides you followed for this?

I've included pics of the pinouts. It's just an stlink V2 clone. You pull it out of the housing and wire it to the pins and the other end to the USB.
You only need to connect SWCLK, SWDIO, and GND. The biggest pain is that you have to solder directly to the data pins, since the data lines aren't connected to anything (yet). But some enameled wire and a little flux, it shouldn't be too hard.
