Reverse engineering 161 in 1 cartridge to change Rom games

You're right I forgot to mention that 😅
Was more focussed on the soft that the hardware it seems 🙈
Yeah in my opinion it's absolutely mandatory. Writing to this Chips is at ease afterwards. I only had one Chip that had totally corrupted blocks and could not surpass this.

Before it were like 8-10 Chips that seemed "dead"

Unfortunately, the voltage mod is not a magic bullet. I've now purchased over 50 "brand new" F0095H0 chips that have never been soldered before. They are all pulls (you can see the residue of the sticker on the face of the chip). Failure rate is about 15%. Every time I asked for refund for the dead chips, I get it in under 15 mins! The seller dumps these on AliExpress without testing them. I'm guessing surplus from making multicarts?

Failure range from data lines open to internal shorts per new firmware.

I'm still trying to understand why they no longer make/sell these multicarts. The only component that I can't buy on its own is the CPLD. Have they run out of this 20 year chip?

Very nice. I'm waiting for the code update (currently, QoL and menu is not in the github).

Also, you didn't mention the voltage mod. It looks like a "must have", easily done with the diode on the adapter.

Whats the Voltage mod?

Legendary ikari you're talking about just prepared his GitHub repo to commit his latest changes ^^

https://github.com/mrehkopf/VTXCart/blob/enhancement/CHANGES-ikari.md

It's a more or less complete rebuild of the original programmer with a lot QoL features (like open line detection, short detection, flash resume, pre check if data needs to be written etc) features a simple file manager (cycle through all files of root directory) and is even slightly faster than the original programmer.

This is a preview as he will review the code once again after he pushes it to the repo 👌

In case anyone wants to try it out, I pushed a binary release along with all the code a few days ago:
https://github.com/mrehkopf/VTXCart
Firmware binary download: https://github.com/mrehkopf/VTXCart/raw/refs/heads/main/Dumpers/Firmware/bin/cart.bin

NOTE: Only P, C, and V ROMs are supported at the moment; I don't have adapters for S/M :D

Thanks again. I've been using it for some days now and it works really great.
Testing is cool, retry is cool, restart on error is cool, skip when already programmed is cool... did I say I find it cool ?

Thanks for sharing it.
Don't be ashamed for S/M, they can be programmed with "classics" like T56.

Hi Ikari, so many thanks, I use your binary and the voltage mod. With the old firmware I have so many problems to program the chips but with your firmware some chip become to life, and one of Best feature is the short detection, but sometimes for me Is so Hard to find the shorts, is possible a image reference for the pin number on F0095H0. I don't have any problem with my pogo programmer, but when I put the chip on the adapter, sometimes I have problems to find the shorts.

Anyway soo many thanks.

That picture is flipped vertically, basically the circle should be at the bottom left and then it's a bottom view of the chip. I got confused a lot because of that :whistling:

This is the correct image I created for my stuff with the correct pinout. It also matches the pinout as written on some PCB revisions. Moving the "dot" is not sufficient. Note the pin numbers.

I wasn't sure how to do this digitally, so I just wrote all the correct ones next to scratched out ones on a printout. Thanks for making things easier for folks!

The voltage mod saved 42/46 chips I'd thought were dead, so very appreciative for that. Like you, most of my failed chips came from abroad. The ones I bought domestically haven't been nearly so temperamental (not that they didn't at some point come from overseas, but it was years ago now rather than in the past year).

Never tested, but with the right adapter this should be ok too.

Has anyone used the xgecu t48 to program the S/M chips?
Do you know if the adapter EX-C is the correct one? I bought this one as per the AliExpress description, but now checking on the programmer itself, it's asking for the EX-A ...
