Hacking Problem with EZ Flash IV playing games over 8mb

[RUFiO006]

Hi everyone. I bought an EZ Flash IV for my SP and it works fine for any rom under 16mb. However, when I try to play any game around 16mb (e.g. Minish Cap or Pokemon Leaf Green), I get a white screen on regular firmwares and a Game Boy screen with no Nintendo logo on the RESET firmwares.

Additionally, my NOR is messed up, even with the NOR fix firmwares I found. I don't mind this too much, as I don't want to play any 32mb games. I just want to play Minish Cap / Pokemon, which should be possible with PSRAM right? At present I'm using 1.74 RESET, however I've tried practically all other firmwares with no results. Note: Games under 16mb (such as 8 and 4 mb games) work fine.

Any advice, or is my card just a dud?

Thanks!

Well, nobody's posted for more than three months, so I'll take a crack at it. If I had to guess, your PSRAM and NOR are both probably duds, if installing firmware didn't change anything.
If it works on other systems, then it might be a connection issue, otherwise... yeah.
