 1 | # `chrome-extension-dmm`
 2 | 
 3 | Chrome extension for bypassing area errors on [DMM](https://www.dmm.com/).
 4 | 
 5 | The following area errors are handled:
 6 | 
 7 | - General DMM cookie-based area restriction is fixed by changing (`webRequest.onBeforeSendHeaders`) relevant cookie value.
 8 | - KanColle gadget server area restriction is fixed by redirecting (`webRequest.onBeforeRequest`) gadget server requests to a third party [cache](https://github.com/kcwiki/cache), so it works like a CDN via GitHub pages (Fastly network).
 9 | 
10 | ## Installation
11 | 
12 | - Open Extensions tab ([chrome://extensions](chrome://extensions))
13 | - Make sure `Developer mode` is enabled
14 | - Load this folder (extracted from [ZIP file](https://github.com/kcwiki/chrome-extension-dmm/archive/master.zip)) by dropping it there or using `Load unpacked` button
15 | - You should see a new extension enabled (DMM 0.0.2)
16 | - Loading, e.g., [KanColle](http://www.dmm.com/netgame/social/-/gadgets/=/app_id=854854/) should work now.
