Missing info we need

• Flash kit you use
• Flash kit software and version

Never heard of this issue before but if your kit can set save types up this may be the problem of incorrect save types detected if it detects at all

Huh, so your GAMES are recognized, just not the saves? Weird. Sometimes my flashcart isn't recognized but that's because the MicroSD card isn't properly in place...
Can you find the save files if you insert the MicroSD into your computer?

[Strider]

yes i can find THE SAVEDATA on my computer, and weirdly, there are like 4 or 5 maybe more of the save.
i'm using a R4 for my DS, don't quite understand 'bout that,
R4 version 1.4.2, in the past, i used 1.4.1, and i foolishly updated my DS, so i have to buy 1.4.2, and the save data gone on BOTH of this r4, DS XL, blue.
any help?

R4 firmware is not what I was asking about, firmware only effects the version of console not rom compat

but seen as you are using a R4 clone though the exact version you have not giving me that info, then I recomend looking at the R4Wood software for it if you have not already

as for firmware you can update that yourself with a DSlite or DS original if you can find someone with one
