Hacking Firmware issues

[ooLIAMoo]

I have a R4i gold card from the website www.r4ids.com - but that place is long gone.

The front cover says:

R4i Ver2.0
Revolution for DS
(DSI/LL/XL/DSL)
www.r4ids.com

I don't know any firmware that 100% work on this card and wont run into errors/games not being able to play.


If I can, can this card (if you have one) do the following:

Run old DS Homebrew?
Play GBA/emulators that work on DS?
Be used on a 3DS running 11.5.0-38E firmware with Luma3DS + Boot9strap?

Thanks.
