Hello, I am looking for a good checklist app. It needs to be able to have 750 or more checklists. I am trying to have a checklist for Nes games. I have downloaded most of the free checklist apps in the market, but when I try to use the import feature it tells me there is no file on the SD card. I assume these apps have a size limit. I have about 250 Nes games and I have a hard time remembering which ones I have already. Thanks for your help.
