Hacking EZ-Flash IV Cartidge not working

[CharlieW13]

I just got the EZ-Flash IV a few days ago, just getting around to using it today and it isn't working. On my DS Lite it says " There is a DS option pak inserted", and on my Gameboy Player the nintendo logo either isnt there or is messed up. First, it wouldn't save my progress in any games loaded to NOR mem. and now the cartridge isn't even being recognized on my console. I don't know what I have to do to make this work but any help is appreciated.

If it worked at first and now has garbles logo/option pak then it is usually dodgy contacts or dirty contacts. Clean them (cotton bud/qtip and some solvent/cleaning fluid that is not going to leave anything behind) and possibly fold a bit of paper a few times and stick it between the shell and the PCB to try to force better contact.
