[GB] Flashing a cart with 39SF010A

[p0ojisan]

Hi, I'm now building a DIY kit from orange fm gb.
https://orangegb.com/orangefm/diy.html

This DIY cart uses SST 39SF010A flash memory chip on it. I tried all of flash menu in cartreader, but failed to write with an error message:

Flash ID: FFFF
Unknown flashrom

Someone can tell which flash menu I should choose? Or doesn't cartreader support this kind flash memory?

This Flash are not supported

I got it. Will try other flasher.

Thanks!

All you need is programmer like « T56 » and adapter for TSOP-32

T56 programmer looks pretty expensive. I will try other flash tool recommended in the kit guidance.

Thank you, anyway.

Could you check if the 7th pin on the flashchip connects to the third pin on the edge connector?

[p0ojisan]

Yes, they are connected. I've confirmed all the pins. Result is like this:

And also here, luckily I have some picutres before soldering.

Let me note that I bought a clone of GBxCart RW after this and it successfully flashed to this cart.

If OSCR also supports this type of flash memory, would be helpful for others.

Added the Orange FM 39SF cart to the GB repro menu:

Hi Sanni,
Is it possible to add 39SFxxx to the SNES repro code and the flashrom (but I think they share the same code, right?) please? I have snes cartridges with 39SF040.

Added the Orange FM 39SF cart to the GB repro menu:

Thank you so much, Sanni.
I confirmed it worked successfully in HW3 as well.
