Should I get a new flashcard or is there a way to update it?

I have a microsd usb 2.0

I don't exactly know how to tell what version the R4 is but on the card it says

R4
Upgrade
Revolution for Ds
(NDSL/NDS)

 

Your firmware may be able to be updated, if you can find out what firmware you are currently on (look for a number somewhere on your main menu of the card).

There are a couple R4 Upgrade cards. Check the cards on http://www.linfoxdomain.com/nintendo/ds/ and see if any of them are the one you have.

 

I'm on V 1.24...can I update it?

 

If there is an updated one then you can.

 

I don't understand very well your post but...

R4 is always the worst flash card of all (lots of incompatibilities, bad firmware, needs lots of patches,etc, etc, etc)
I recommend you to buy an Acekard 2i, but if you want to save money... well yes there are ways to "update" your firmware.

Where can I find an updated one?

 

i doubt you can find a r4 "super updated" most of times you need to update it by yourself

 

I've decided I'm just going to buy new software...is acekard 2i the best of the market? I can make the investment of $30

 

is the best and is compatible to dsi... but there are always other oferts (cyclo ds is good too) there is a topic in this forum where they explain more details, let me see if i find it and i will give you the link

You find the update version of the r4 by going to its website or gbatemp.net.

 

...Maybe i get confused of what he said... sorry.
There's always ways to update your firmware, in that way you will be able to play "more" games with your r4
