Hacking Identify R4i Card?

[digids]

Hi, I recently picked up an R4i card, I have a DS Lite.

I have tried all the software under the 'Everything R4:' at this site http://www.linfoxdomain.com/nintendo/ds/
most don't work and I get a 'loading' or white screen, but some appear to work; the interface loads but once I pick a ROM to load I either see a 'Loading' screen or some random characters '0b0b0b0b' etc.

Below is the circuit board and outer casing. I'm really hoping someone could please help identify this so I might be able to get it working?

Thanks very much for any help

Update: the download titled "r4dspro.com Latest: v1.50" from http://www.linfoxdomain.com/nintendo/ds/ seems to load, but no games load.

So I tried a firmware updater "fwUpdate_V5.06.nds" by Bruno, I didn't run it but it did load and it tried to list my firmware, however it displayed "unknown"

I have a feeling I may have used an EZ Flash in my DS so perhaps I need a new firmware for this R4 card to work?

Also: I think this card is know as NDSi-507 possibly from tvc-tech.com

there also appears to be one for sale here: http://www.worldofelectronics.ie/R4_Gold_R4I_SDHC_for_NDSi_NDSL_NDS_507_p/ndsr4-1.htm but no mention of software.

Does anyone have any advice that could help?
Thanks very much for any replies :-)
