For simply, your question is which eroge can be played without changing system locale right?
Is that so, the answer is you have to test yourself. As my experience, there are eroges that can be played without changing ( including fan translated, not translated....etc ) and do not use any application to temporary change system locale ( HF applocale ). There are eroges that can work with applocale. I don't know how many, but if you want to play without facing any problem, changing your system locale to japanese is recommended. Some eroges even need you to change your whole computer including keyboard, time zone...etc.
Because my pc is always in japanese location so i don't know. Just change only system locale in tab administrative, i can play most eroges while my PC still display in english. When having error, i will change the whole to japanese and after done, i change back.
Hope that help you find a convenient way to play eroge. :)
