    R4i-SDHC.com v1.87b kernel released (timebombs removed)

    Have you tested this yourself? I was wondering if 4.3 was also removed? The r4isdhc.com and r4i-sdhc.com cards are firmware compatible with each other, so they can be easily replaced using ntrboot_flasher. https://gbatemp.net/threads/differences-between-r4isdhc-and-r4i-sdhc.657284/ 1732419040 I...

    Stargate 3DS - PCB and firmware

    Converting ROM to card2 will make it work. 1732294770 Failed to read the save. It turns out that UP flash is the save itself, so card2 should not be affected. I think the cause might be a poorly soldered UP flash.

    Best flashcart for 3DS?

    PCB itself looks original to me. Quality is quite good.

    Stargate 3DS - PCB and firmware

    I bought another one and it arrived today, but it has a save issue. To check this out, you can make a save with 2 Zelda games and run them alternately and you should be able to figure it out. My guess is that someone plugged it in and returned. I'll take it apart and dump it just to be sure...

    Stargate 3DS - PCB and firmware

    Since there is no direct connection from the ATMEL chip to the FLASH, I assume the FPGA programs it instead. After testing a bit more, it seems that simply connecting it doesn't change data. Most likely, it was the input with PuTTY that changed data.

    Ace3ds X PCB and firmware

    That's good. It seems like some people have gotten blank flash from Ace3ds X. Since it's the same firmware as the Ace3ds plus, there's no card specific data either, which is nice.

    Ace3ds X PCB and firmware

    Yellow arrow GD25LH80BM (1MB) SPI FLASH. Firmware for ntrboot. Blue arrow W25Q16DV (2MB) SPI FLASH. Original firmware. ---Update--- In ntrboot_flasher you can't dump it. It has the same firmware as the Ace3ds+. The only difference is that you can choose the firmware for ntrboot. Fixed an...

    If R4's recognition fails frequently, it may be a sign of EEPROM death.

    Long-term results After a long time, neither of them worked. So I dumped them and found several broken data and concluded that it was a broken W25Q16BV SPI FLASH. I expect there are many variants, but I can't recommend the cartridge labeled BL2CK OS with W25Q16BV SPI FLASH.

    Stargate 3DS - PCB and firmware

    I haven't seen how this changes since it's not possible to do an in-circuit dump. This is not possible due to my lack of knowledge.

    Stargate 3DS - PCB and firmware

    I haven't tried card2, so I don't know. I thought it would have a widespread effect since so many points in the firmware were changed, but all I saw was a corrupted save.

    Stargate 3DS is pretty good.

    Dumped with the CH341A programmer. Seems almost impossible to change if it has nothing to do with Alex rider.

    Stargate 3DS is pretty good.

    The best solution is to change the firmware of the cartridge itself, but I can't find an easy way to update it. I looked at the firmware and there is a slight code change starting at 0x7C00. Probably the code that runs _ds_menu.dat. The rest is pretty much same as Alex Rider game. 1730398610...

    Stargate 3DS - PCB and firmware

    UPDATE 2 (final) UP(SPI FLASH) has been corrupted by the act of connecting to the USB. This corrupted the game's save and only worked after restoring the original data. It is never recommended to connect the STARGATE 3DS to a USB. UP(SPI FLASH) is associated with the game's save (SD card) and USB.

    Hardware GBA FLASHMP SuperCard micro SD?

    If you are comfortable with soldering, you can try it, but the cost of replacing it for 1 is not better than buying a new one.

    Stargate 3DS is pretty good.

    https://archive.flashcarts.net/stargate-3ds.com/SG_Launcher_CFW There's a launcher that makes it easy to use DS mode. If you run the launcher while in DS mode, it will launch successfully.

    SRAM is represented by 04(512KB) or 08(1MB). They are now more than twice as expensive as when I bought them. aliexpress.com/item/1005006071577708.html aliexpress.com/item/1005006011870208.html This is the same one I bought. (S71PL032J08BFW0B)

    In the photo, it appears to be an S71GL032A40. This is 512KB PSRAM. That's less than I had before. :unsure:

    It might be possible to add DSONE to ntrboot_flasher.

    I recommend using Ace3ds X. 1730268484 It looks like it was dumped normally. The point at which a restore may fail is when a write command is not possible after erase. If it's a flash with a different command, it's not a problem because it doesn't proceed from erase. However, I haven't tested...

    It might be possible to add DSONE to ntrboot_flasher.

    I resized it for dsonei. I excluded chip id recognition because there are many variations. So this can be very risky. Just make sure the firmware dump works. Unless you have a specialized programmer like xgecu t48, t56, etc, I don't recommend trying to restore. If you are willing to take the...
