    Misc Project Did the DSi Capture Card End with Katsukity?

    That's quite neat. I've been moving forward very slowly with my "custom DSi devkit" project idea (with JTAG access and everything), which would also necessitate making a capturecard (I was thinking of using the CH32H417 instead). But then hopefully I can reuse your design maybe?

    Hardware nintendo DSi CPUs

    Cool, looks like they have much better illumination of the die (and thus, better contrast) than me. I might have some time in a few weeks to play with the IC scan setup again, to see if I can get better illumination.

    Misc Project Did the DSi Capture Card End with Katsukity?

    Cool, looks like I won't have to scrap this project from my TODO list then.

    Misc Project Did the DSi Capture Card End with Katsukity?

    Are these install-service-only or would I be able to just order one & do so myself?

    Hardware nintendo DSi CPUs

    For the CPU xxx <-> LRxxx mapping: a few years ago, some PDFs from Sharp were discovered just being accessible online without login. These two documents: a, b both list LR359Ax chip numbers, but the final digit is missing. However, with the SCFG_JTAG and SCFG_OP docs, a pattern becomes clear...

    Does this work? EDIT: original size (26 MB) here: https://pcy.be/tmp/img/49548423821_c618b33e2d_o.jpg

    Hardware nintendo DSi CPUs

    Had to dig a bit for this, but, a long time ago, others tried decapsulating the CPU-TWL, but they also only imaged the top layer (aka the kind of useless layer). It looks like this: . The IO pads (and die shot in general) look the same as your LR359A12 die shot, and different from your...

    Hardware nintendo DSi CPUs

    Hi, someone pinged me with a link to this post (I don't look at GBATemp otherwise), so I guess I'll write what I know by now. The current hypothesis is that the only functional difference is that the dies are bonded out differently, which is reflected in the SCFG_OP IO register. This register...

    Nintendo DS IPS/AMOLED Screen Mod

    DS capture cards' hardware/FPGAs are kind of Old and obsolete, so making new stuff with it is hard, because finding these chips is difficult, getting the toolchains for them to work is difficult, and so on. You'd probably be better off making a new design with a more modern FPGA or...

    Misc Project Did the DSi Capture Card End with Katsukity?

    Plus, it's embedded (baremetal, OS-less) programming, while also trying to make something do something it's not quite supposed to do. Mightn't got all that well as your very first venture into programming (also because C (the programming language) kinda sucks, and Rust has a steep learning...

    Misc Project Did the DSi Capture Card End with Katsukity?

    Yes and that's literally what my first post in this thread is about. I guess I have some claim to be included in those "smart people", and I can tell you that such a project is a bit more involved than "just" doing a few things. Insisting that "someone" does it feels rather dismissive...

    Misc Project Did the DSi Capture Card End with Katsukity?

    The OP says: So there doesn't seem a good way to do this. Furthermore, the post also states that the archived download includes Verilog sources. Problem is this was written for a piece of hardware (both the FPGA chip and the development board) that's super old and not made anymore...

    Misc Project Did the DSi Capture Card End with Katsukity?

    Fwiw, I've thought about this a fair bit as I also wanted a DSi capture card (because it's the only thing that can properly record the hacky stuff I do on a DSi, which a 3DS can't). (Also, FYI, I'm the one who made the DSiXL testpoint table. I'll see if I can fix the duplicates sometime soon.)...

    DSi bootrom dumped andnew exploit disclosed @37th CCC

    Apparently the conference where it was accepted is being really slow with their proceedings, sigh... Anyway, I've attached a PDF of the proceedings version, enjoy.
