...does anyone know what these EX's do?
Only the developer of No$Zoomer knows for sure and his readme for No$Zoomer is in plain japanese.
All info about the EX options available is mostly guesswork done by several people here in the forum.
From basic information from Avalon code and Nostalgia, EX0 removes the problem with none refreshing text on a screen.
And it enables otherwise hidden gfx like in Nostalgia (eg. Options menu).
Also sorry for my wee outburst I do not take kindly to being rudely talked to without some sort of full explanation of WHY I was wrong.
Not only do you simply push out totally false info which can ruin someones hardly worked on savegame (what I've explained in my post above already), you are also:
- not able to do a propper search in this forum (which would have given you a lot of valuable info about No$Zoomer and the EX options)
- not able to read properly what someone else told you about your wrong info
- starting to whine about someone correcting you
- assuming that someone calls you an "idiot" by just telling you that you are totally wrong (and you are definately totally wrong

)
You tell to enable 5 out of 5 possible options (1 of them not suited for most games and possibly corrupting the savegame) whereas only 1 has an impact at all for this game.
Calm down... read my above post again... do a search for No$Zoomer in this forum... think about what you have told a poor guy asking for
propper advice and assuming what he was told by you was correct.
Sincerely the guy who just told you that your advice was totally wrong.
