You can simply download it. (rotmg site/AssembleeGameClient[version].swf) current version is 1344965814. It will join only rotmg testing. ( silly protection, that can be patched with one byte)

but then i cant see connection thing right ??

you can use marine powers to detec connection.

on testing ?

Not actually marinepowers but:
(http://www.mpgh.net/forum/599-realm-...roxy-base.html)
can be compilled int working game proxy.

i belive it's also possible to changing host file to make marinepowers work on testing.

Hah it's seems to be easier than i thought. You can make marinepowers work with testserver in very simple way. All you need is to edit dnsmapping.cfg and add correct server adress. You can get server adress from [rotmgsite]/char/list just look for <server> tag.
