The 8.412 will work fine as an SE version.
Same for most Navcores designed/modified to work on 32mb devices.
Only problem is the slow CPU, so you should avoid the full featured maps or at least LoquendoTTS.
With normal voices or VocalizerTTS it should work fine using the 8.412 or if you prefer a V9 NC the 9.205 modified for small screen 32mb devices - simply download and check what's working for you.
Some people report good success with most V8 Navcores modified with the DSA tool to work on memory boost.
