    SuperFW: a (very much WIP) supercard firmware

    Oh thanks for the passme advice, I found some information that pointed to that but couldn't test it due to my DS being dead. I will try it once it comes back to life. 1716746188 Ok so about the SRAM and its 128KB capacity. I chatted with Maniac and we reached the conclusion that yeah, only 64KB...

    SuperFW: a (very much WIP) supercard firmware

    Oh right! Totally forgot about this. Checking gbatek it seems that no SRAM game uses more than 64KB, so I'm wondering how the 128KB SRAM is actually mapped. Given that 128KB flash is indeed banked, what you mention about the 64KB hardware restriction seems to make perfect sense. Now the...

    SuperFW: a (very much WIP) supercard firmware

    Oh didn't know that :D BTW my supercards are definitely 128KB (one ships a KM68V1000B and the other a BS62LV1024 chip). Which models ship the 256KB chip?

    SuperFW: a (very much WIP) supercard firmware

    I was just lazy and dumped the entire 128KB SRAM (instead of trying to detect the save size). I might improve this in the future (detecting save size is not complicated).

    SuperFW: a (very much WIP) supercard firmware

    Thanks for the report! I also noticed that the Lite has some quirks (I found some funny comments in SCFW and devkitpro sources) so I was wondering whether my FW was at all compatible with this particular model. It seems it's not easy to find any more (only the regular microsd version is still...

    SuperFW: a (very much WIP) supercard firmware

    Hey there! I'm back :) Answering some questions now, thanks for the feedback! Will the card still support passme to run DS homebrew? > For now I'm focusing on GBA mode (also my NDS died and I don't have a SuperKey with me for testing) Looks great, might this also work for a supercard miniSD...

    SuperFW: a (very much WIP) supercard firmware

    I tested this in a Supercard with microsd and minisd (I do no think it is relevant, it's just the same kind of device). I haven't added support for flashing the internal flash yet, I assume that might be tricky, given all the messages in the SCFW thread, right metroid maniac? Seems that there...

    SuperFW: a (very much WIP) supercard firmware

    Hey there! So yeah, after seeing that this was pretty much possible (thanks to metroidmaniac's effort) and since this was something that I always wanted but nobody came up with, I decided to give it a shot and try it myself. I've been working on this over the past 2-3 weeks and so far it looks...

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Thanks for your reply! Yeah, diffing ROMs might be very helpful to find how they are patched and fix non-working games. I saw that some games have very specific patches (tho only a handful) and the majority are properly patched with the WAITCNT register write finder. But perhaps there's room to...

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Pretty cool project I must say! I stumbled across the original post by coincidence and to my surprise a few weeks later boom! Do you have some more information about the hardware? I know it has a flash and an SDRAM chip (used to hold the ROM), but would be nice to understand how things are...

    GBA wireless adapter emulated on 3DS

    Thanks for the feedback. I was not aware of that project, but it would be super amazing to implement some sort of wireless compatibility layer. I also learned (thanks to your comment) that some similar projects exist for DS/DSi (like GBARunner2 ?). Perhaps we could have some sort of...

    GBA wireless adapter emulated on 3DS

    Ok the title is a partial clickbait, sorry for that! This might belong to the GBA forum perhaps, but 3DS owners might also welcome it. I spent the past month working on reversing the GBA wireless adapter along with some folks who already did in the past or are doing right now. I implemented this...

    Sonic mania 3ds port released!

    Hey there! I recently got a 2DS and I was stoked to play Sonic Mania on it (my switch sorta died and it's not very usable). However load times are teeerrible. So I went ahead and proposed a small fix that makes load times up to 4x faster! Sent a PR to the upstream repo, and in the meantime...

    Homebrew RELEASE reicast [Dreamcast emulator] for Switch/Horizon [Alpha]

    Hey just a heads up, no longer workin on this. However most of the code was upstreamed (by me) to reicast, right before the flycast fork, therefore it will definitely land on Switch as a Retroarch plugin or whatever it is called. Stay tuned, these guys are working really well and it should be...
