Some basic search engine terms to use when searching for Japanese hacks:
"ハックロム"
"改造"
"自作ゲーム" is for homebrew games.
This should cover defunct & active GeoCities-type sites:
https://ja.wikipedia.org/wiki/Wikipedia:ISP%E7%AA%93%E5%8F%A3
Some defunct ones not listed include:
atpages.jp - closed February 28 2018
freett.com - closed March 31 2016
Subdomains are page.freett.com & big.freett.com.
If using Google, change the regional settings in Google.com's options or just use Google.co.jp.
It affects search results.
I'm looking for anyone to reupload any ROM hacks or NSF/Famitracker files found on pan.baidu.com.
The hack threads are usually here: https://tieba.baidu.com/f?ie=utf-8&kw=hack游戏
If you want anything else included in the patch archive, drop a link in the /hbg/ rom hack general of 4chan's /vr/.
I should get around to it eventually.
