Oh, I now get it. Okay. So then bad news is that some visual novels don't just need supporting exe files, they are programs in and of themselves. So, there are two ways to run them on android.
Buy them from the market or amazon (I had a few a while ago but I do not remember what they were.
Take yours and port them.
The latter is going to be difficult and beyond my expertise.
However, after some research, I found this thread.
The app is still in the market and it is only 1.99 in the US.
In order to run an app on the nst, a few conditions need to be met...
You need to root.
The app needs to be made for SDK 7 which is pretty old, but there are sometimes ways around that involving tricking the app to think it needs a lower SDK.
You the app needs to be compatible with the nst hardware.
After you root, I suggest you try. good luck. The Net that I ordered does not have working touch so I am awaiting my replacement.
Go forth and work toward your salvation with diligence.
