Several applets on a page, but only one works

[mobluse]

I have three applets (same applet, but loaded with different Java ME apps) on http://df.lth.se.orbin.se/~mikaelb/microemu/all.html , but only one (the rightmost) is running correctly using https://cjrtnc.leaningtech.com/3.0/cj3loader.js. Here you can see all files in the folder: http://df.lth.se.orbin.se/~mikaelb/microemu/. The applets should not communicate with each other. The applets work individually using their own pages: http://df.lth.se.orbin.se/~mikaelb/microemu/blockis.html http://df.lth.se.orbin.se/~mikaelb/microemu/aritm.html http://df.lth.se.orbin.se/~mikaelb/microemu/weekno.html

If I use CheerpJ 2.3, using the orange button (shield with bean), it loads the wrong apps into the applets and if I click buttons in one applet it changes things in another.

Here is how it should look (IE mode in Edge using Java 8): I prefer to be able to use CheerpJ since not all users have Edge and Java 8 installed and know how to configure Java security.
