Getting Papa Sangre and Other Something Else Games to Run

Hi,
I have the IPA files for Papa Sangre 1 and 2, AudioDefence, and The Night Jar. I would like to get them loaded onto my iPhone so that I can play them again. I know they're not available from the app store anymore, but I was wondering if there was maybe a way that this could be done through something different? I'd like to relive old memories, and potentially actually get around to beating the games again.
Thanks,
Rich
