LOL, since when did I make an Android app before? I only did some conversions to apk for some Ren'py visual novels before, nothing fancy.
Anyways, I'd like to make a comparison between the portable devices that you can run ENGLISH visual novels on:
NDS / 3DS:
- Needs a flashcart to run VNDS and Fatal Relations (homebrew)
- Has 999, Love Plus, Tokimeki Memorial Girls' Side (Otome)
- Really good battery life, good use of double-screen
- Cheap price
PSP / Vita:
- Has homebrew conversions for Yume Miru Kusuri and Divi-Dead
- Translations for Hakuouki (Otome), Milky Holmes, Corpse Party series, Ore no Imouto (upcoming)
- Reasonable battery life, but screen sometimes makes it hard to read VNs
- Cheap price
Android:
- Emulators to run a lot of older visual novels (DosBox, PSX)
- Google Play market has plenty of visual novels
- Has VNDS, Onscripter, Ren'py and xClannad apps
- Reasonable battery life, best read with a 7.0" tablet minimum
- Price varies, but a cheap Chinese-brand tablet would suffice for playing VNs
iPhone/iPod Touch/iPad:
- Emulators to run a lot of older visual novels (DosBox, PSX)
- Translations for Steins;Gate and Chaos;Head Noah (upcoming)
- Has xClannad, and upcoming VNDS support
- Plenty of English VNs on Apple Store, including MangaGamer's Kira-Kira
- Good battery life, recommended to use iPad for reading
- Expensive
Windows-based tablet/UMPC:
- Can run just about any Windows VN, or emulators
- Weight may be an issue for portability
- Battery life moderate
- Expensive
This is the basic gist of it. I know I'm missing a lot of points (just woke up and typing this atm, lol).
