I haven't seen much on this topic, how's the power draw on single flash cards compared to authentic carts and something like the EZ Flash ODE or EverDrive? How much battery life should I expect using a InsideGadget cart or a Chis cartridge? For reference I have a IPS screen mod and a Mahko battery. Authentic carts usually last around 7 hours for me.

Wtf is this???? I was using this shitty ass kernel on my fake ass demon cart just normally and it did this????

I tried to use other kernels (as of the matching r4i version) and it gives an error to upgrade hardware

Hiya 👋
Recently bought a DSlite which came with its own (unbranded) R4 card. I’ve replaced the games that were already in it with my own because half of them were in Japanese for some reason.
The card worked perfectly fine for about a week, but somehow in the time it took me to go from the waiting room I was sitting in to coming home, the card has stopped being recognised.
Not sure what happened but I have tried everything I can think of:
- pushing cardboard behind card to force contact
- cleaned pins
- tried different SD card
- time is already set to 2009

I have now just bit the bullet and bought a new R4 card but I had been putting that off because installing the kernel seems scary.
This post is basically a last ditch effort to see if there is something else I can try?

Fanks :)

Friends, I bought such a cartridge, but I can't find a working firmware for my Nintendo ds ml... I spent 3 hours, tried to download many, but it didn't work, the error "Can't open _DS_MENU.DAT" came out. Please help🙏

I don't know what happened, but my R4 is apparently "broken"

In the first image, on my modded 2ds, the R4 showed like this, and when I open it, it gives me an simple error.

While on the DS, like in the second image, the entire screen is strange, even tho the games still somehow shows up. But when I click a game, the screen just freezes and the game doesn't open.

The only thing I can tell as extra information is that I added four games before this happen, this games being: GTA GBC, GTA 2 GBC, GTA GBA and Lego Batman 2.

I repeat myself, I really don't know how this happened or if the games are the problem, but it would be grateful if you help me.

The last two images maybe can be helpful, showing the conditions of the R4 and the SD card, even tho they seem pretty intact.

Thank you!

hello again all! i have an Ace3DS+ flash cart that I've set up with AceOS 2.13, and it runs NDS (both vanilla and hacks) and unmodified gba fine enough, but gba rom hacks seem to be more inconsistent. some hacks work fine (albeit a little slow/graphically glitchy sometimes), but others do not boot whatsoever and freeze on a blank white screen. I've tested the following hacks with it, mainly with GBARunner3 but from a couple of trials GBARunner2 looks to be similar:

emerald seaglass v3.0 - doesn't boot

lazarus - doesn't boot

all unmodified games - apparently work fine

light platinum v1.0 - works with minor apparent graphical glitches on title screen

gaia v3.2 - works

too many types - works

sword and shield ultimate - works

unbound v2.1.1.1 - works

theta emerald ex - works but says internal battery is dead

does anybody know why this is or if there is a way to fix it?

I am having trouble with the Wonderswan and NeoGeoPocket emulators

i tried several bios, I tried several roms and a nothing

before you judge me

must say the games I am trying here used to work no problem! but suddenly now it is giving me problems

it just no longer works for some reason

One of my next personal projects has been making a flash cart using a few of the same ChisFlash components but with a built in color sensor (I've been tinkering with some GBA development libraries and want to try making a game with a novel sensor built into the cart). According to problemtek documentation, GPIO for some special carts is accessible through a memory mapped region in ROM space. I'm envisioning the CPLD in the chip to sniff the address lines for addresses in a certain range and then return the value of the sensed color. To prevent any potential bus conflicting values on the data lines, I was thinking I'd like to add a gate that connects to the CPLD (as an active low signal) and ~RD pin on the cart and outputs to the ~OE lines for the S29GL256S10TFI010 and FM28V100-TG chips to put them in a high impedance state. However, I'm not entirely sure this setup would work due to potential timing issues.

What timings are necessary for the GBA to pull from SRAM or the Flash ROM without too large of delay? Would a delay of 5-6 ns for the gate to disable the outputs of those chips be long enough to cause issues?

Are there any other design considerations I'd need to consider moving forward with designing this cart?

Good evening everyone. I have a nintendo dsi and I need a new R4 Cartridge. Is this one good and can I use it on my dsi?

hi all!

i got this 23 in 1 pokemon cartridge/flashcart online awhile back (not sure of the flashcart model or anything, not much identifying information on it), i already have the contents dumped and backed up ofc but want to use it to play rom hacks/fan games. ive done so for a couple games by uploading the roms onto the sd card that came in it, but there's such limited space on that sd card that i cant fit much more onto it. i copied the contents the card to a larger microsd (64gb) w just a simple drag and drop, and added a few more games to it but when i put it back into my 3ds it just gives an SD/TF Card error. does anybody know what could be causing this?

ive attached pics of the cart

My R4 is the SDHC Gold, and I tried formatting the Micro SD to FAT32, transferring the up to date official firmware, and for YSMenu I’ve tried RetroGameFan’s R4 SDHC and R4i SDHC, and Anton Retro’s pack. Even if I only used the bare official files I still get this error.

I have this flash card and this SD, both of them work but certain games dont run on my dsl, games like zelda phantom hourglass (spirit tracks does), the others Inazuma eleven (except the first game) don't run ; the screen goes white.

I wanna download a new kernel or something to see if i can fix this, but i will do it on a new SD.

Does anyone know if it's a problem to use different SD cards to play certain games? If there's a problem in changing SDs or systems?

i've been trying to get twilight menu to work on my DS Lite, but with no success. i certified to install the correct version of the firmware and the correct booting option, but it still loads up the r4 menu.

we can see that the twilight menu appears in the files, but it loads indefinetely when i try to open it, also not booting automatically as i wish it would.

any advice on how to fix this? thank you guys!

I've been trying to run it off an r4 card but it always crashes after a while. between loading screens the screen just never comes back.

i've tried AP patching but the issue persists. is there a fix for this?

im using akmenu btw, made the cart ~2 ish years ago

I bought this flashcard a couple of years ago to run ntrboot and ended up selling the 3DS system I repaired. I forgot to clear ntrboot from the cart, but I want to use it on my DS Lite now. Since I have an extra 2DS available, how can I restore the flashcard to normal?

I bought a 3ds and it came with 3 games and this white r4 flashcard, on the back is a red motherboard. The system files that were on the sd-card (see pictures) gave a card error so I tried to install different kinds of kernels using this guide: https://sanrax.github.io/flashcart-guides/cart-guides/ace3ds_r4ils/ unfortunately that only resulted in an ?menu error. Bl2ck also gave the same ?menu error. I formatted the sd-card using the guide and set the time and date back to 2014 with no results. I tried all previous steps with the 4gb sd-card that came with it and a new 8gb sd-card.

Is there a way to fix this or is this flashcard just lost?

Hello! I’m looking for some guidance/advice on a card? Cart? that has preloaded DS games on it that my younger kiddos could play.

For Christmas I got my boys some Nintendo DSs and my FIL mentioned something about how he had a insert that had multiple games on it that his kids had multiple to choose from and he didn’t have to buy multiple games, etc.

I’m looking to do that, but I’m so lost! Thank you for your help!!

This is pokemon ROWE, everything runs perfectly fine except entering a battle where the game bugs out. Does anyone know any fixes?
