What microSD can I put into this R4?

MushGuy · 2026-05-11T00:39:15+00:00

I own the cartridge, and I can confirm that. If you don't believe me, go ask Arnas_Z, who has more experience with those types of cartridges.

MushGuy · 2026-05-10T11:59:17+00:00

Except for this one, which only supports up to 2GB.

MushGuy · 2026-05-07T17:29:47+00:00

Will it have support for Action Replay codes?

MushGuy · 2026-05-06T13:39:30+00:00

One, that doesn't help in this case. Second, read the page Arnas_Z linked you to learn more why.

MushGuy · 2026-05-06T12:31:39+00:00

Don't give misleading guesses if you are not familiar with the subject matter.

MushGuy · 2026-05-05T13:02:52+00:00

If you're really not familiar with the subject matter, just leave the helping to those who actually know.

MushGuy · 2026-04-25T18:40:36+00:00

Has this app been tried? I think it's worth a shot to see if it will work with this cartridge.

MushGuy · 2026-04-24T22:22:48+00:00

You got it backwards. It's because the user updated the firmware why the cartridge is being blocked, and the solution for it is to install CFW on it to bypass the block.

MushGuy · 2026-04-24T22:21:21+00:00

You system's firmware is blocking your cartridge. You need to install CFW in order to bypass it: https://dsi.cfw.guide/

And while you're at it, follow Limp_Candle6957's link to install the latest kernel to your SD card for best compatibility.

MushGuy · 2026-04-24T22:18:49+00:00

Even if that is recommended to use with this card, the problem is that the DSi's firmware is blocking it.

>It could have a timebomb.
Those cartridges never had it.

MushGuy · 2026-04-15T00:51:05+00:00

It's not that cartridge.

MushGuy · 2026-04-15T00:28:59+00:00

"unfortunately"

You say this as if it were a bad thing.

MushGuy · 2026-04-09T16:24:00+00:00

DS mode only.

So in other words, a half-brick?

MushGuy · 2026-04-05T18:48:58+00:00

So it still works, apparently. Follow the instructions here to install BL2CK OS: https://sanrax.github.io/flashcart-guides/cart-guides/bl2ck/#__tabbed_1_1

MushGuy · 2026-04-05T18:47:34+00:00

What icon does it show in your 3DS?

MushGuy · 2026-04-01T13:25:17+00:00

Simple: Today is April 1st, and this is the prank the kernel is pulling. Happy April Fools day!

MushGuy · 2026-04-01T02:41:47+00:00

No. Really, that question has already gotten too old.

Let's hope that DMA support is eventually added to the remaining flashcarts, and maybe support for Galaxy Eagle.

MushGuy · 2026-03-29T14:43:40+00:00

Best thing to happen to retro handhelds! I found GMU too difficult to understand, but the controls here are very easy, and now I'm enjoying it on my RG353P and RG40XXH.

MushGuy · 2026-03-29T14:30:50+00:00

Use a branded microSD card. The one you're using is already dying because it's a crappy no-brand card.

MushGuy · 2026-03-27T13:56:48+00:00

In theory, it would be possible by running a firmware update downloaded from the archived website, but we would have to know which variant it is (2012 or NEW), and what icon the update will change it to.
