R4 Revolution RTS and R4i from the M3DS People
Yet another R4 Revolution clone is set to be released very shortly, but this one is a bit more interesting. This R4 Revolution is designed by the people who brought you the M3DS. Like all the other R4s on the market, it is just another company which is using the seemingly freely available R4 Revolution name. The difference is that this one is actually connected with the production of the original. The M3DS Team are believed to have worked on the original R4 Revolution producing either the hardware or software.
There will in fact be 3 variations; R4i RTS (with a Real Time Save function), R4i SDHC and R4 SDHC, the latter being incompatible with Nintendo DSi.
They have also just released the M3i Zero which you can bet will be virtually identical in terms of features and design, just with different branding. The M3DS team are essentially trying to cash in on the R4 Revolution name and who can blame them? Everyone else is. This release seems a little more high profile than other R4 Revolutions on the market, but only time will tell if will actually do a better job than those already on the market.
What do you think? Worth buying or just a same product with a new/old name?

What is the difference between an R4 Revolution for DS (NDSL/NDS) and the one mentioned above R4-SDHC Upgrade are they the same
I am looking for info that i got R4 on DS lite (white)…and i have heard DSI XL as it really cool and good size of screen but i just wonder do my R4 SDHC will work on new DSI XL ? or buy differnt R4 ?
You’ll need a R4i for a DSi or DSi XL.
