Hi everyone,

Does anyone know of a way to change the WonderTang firmware and use it as a TNCART V9990 instead of FRANKYSMS? There's a bit of uncertainty.

I've found the programming mode OK at the link above. Where's the info on how to use it as a tncart? Any steps on how to try out a few games or proof of concept?

We found the FW tncart adapted for Wondertang here: https://github.com/herraa1/tnCartWonder

now reading the readme explains that the wondertang cartridge needs to be modified, if it is board v1 or v2, I don't know ours is board of

Ivan needs to be modified or simply flashed with GoWin and off you go.

Luke says that "theI have the "normal" Wondertang, not Ivan's, and the version is indicated on the PCB (they're all 2.0b now, it's hard to find a 1.0). Take the related, already compiled .fs file and flash it together with the Nextor file and the FM file on the Tang. Follow the info you find online, but in practice, you just need to flash it sequentially, changing the addressing value (it's indicated in the info)."

Do we know anything more?

TO.
