ONScripteris an opensource cross-platform clone of the NScripter Visual Novel engine. The original ONScripter was written by Opagee the fork that supports the English language is maintained by Haeleth
After extracting ONScripter to your SD Card you will need to install your game files into a directory under /apps/onscripter/games/.These usually consist of a 0.txt or nscript.dat file and a arc.nsa or arc.sar files.
I experimented with each of the above options before tentatively settling on Ponscripter-fork, to my knowledge the most up-to-date version of the Ponscripter engine (with the added benefit of Steam support built-in). Nothing was able to handle the MYTH script as-is, but Ponscripter-fork looked like the most promising option in terms of providing a pleasant user experience.
