Buying one isn't a hard thing, I even have friends owning one, and about a9lh it's not worth it as well, while a stock 3dsxl is 6000 is you order on websites that sells 3ds, most of them are with a9lh and sell a minimum of 7500+(50 USD min), some may add some low quality accessories and cost you 80+ USD more, add a few NDS games you can have a PS Vita , the most tedious part is they mostly don't mention if it's a hardmod or how did they do it, if they have a bad soldering skill you may end up finding that after a few months, I also think they only have a9lh installed but not cfw with it, most of all, no nand backup no top provided when you purchase it, got bricked? Another 60 USD gone
Are there exploits I'd say pretty much since the console is likely abandoned from Nintendo, but there's no point because hardmod is the main method, and if a9lh is meant for piracy then all games they can install are still Japanese or English games, or on China websites there are some Chinese translated cia they can play, if a9lh is meant for game enhancement most people don't even know those enhancement exist, I tried to search for hacking communities in Taiwan but only board I find a new post comes out after a week, and most posts are just copy paste China hacking forums’ posts, recently they discovered safehax exists and the guide their using is still 3ds.guide, I'd say hacking isn't a majority in twn if you want to help those twn stock 3ds users, but I agree it would be nice to have a twn nand, although even it did exist, as I don't read Japanese I'll still not use it, Japanese contains enough Chinese characters and A for yes B for no applies to every game, I struggled a jpn 3ds for 3 years and another for half a year, nothing bad happened though I don't read Japanese, the only language barrier is when searching Japanese titles on eshop, but that wouldn't help when using a twn nand and twn eshop either
