question...

How come sometimes my ds lite cannot detect the R4-III, sometimes can one?

Because some times the R4 or your DSL the spring inside there cant work or jump on properlly....so might be like this loo....if cant detect....try to inject in and out again...might working.......

hmm yeah that is what i usually do...

quite effective and works..

but if cannot i usually try to turn on and off a lot of times

my sis NDS also the same...once i copy games for her....aik...cant detect d.....bastard 1....darn mah use this trick loo....

by the way, do i need to blow blow the R4 card?

or just keep reinserting the card will do?

hmm....knock softly also can....like GBA catridge last time....blow also can....softly loo.....

ok, one more question:

if i keep reinserting the R4 will it damage the card? or the ds?

you put it that time slowly lo...or softlly.....scare it will damage your nds the slot inside's spring......
