I'm in the same boat. Ive been desperately looking for some kind of iMode emulator so I can play Triggerheart Exelica on my phone.
I found this: http://octoba.net/archives/20100923-andoromeda-android-988.html It appears to be a full blown iMode emulator but the catch is getting it outside of Japan. I struggled with various proxies and play store modifications and I cant get access to it through the play store. If you do manage to get ahold of it somehow please let me know!
