ok so i tried all the above & found it very confusing (mostley because its out of date) so here is what i did ( I got all games working except flo boarding ) 
	first get your emulator eka2l1 or as it is now known eka2l1_qt  here
 
	get windows latest
 
	https://github.com/EKA2L1/EKA2L1/releases/tag/continous 
	get the sys.rom (search Firmware nokia N-Gage) & get all the games 
	check https://eka2l1.miraheze.org/wiki/Important_Links 
	get the n-gage cracked games full romset 
	once you have those run the emulator & it will come up with no system files installed (or something similar) in the emu file/ install device & select your path to the sys.rom. 
	close & reopen the emu. 
	now to install the games 
	first off, unzip them ( i used 7zip, but you can use winrar if you want) 
	now there are 2 ways of installing them in the vids i saw. 
	so i did both ( you may only need to do 1, maybe someone will help with this) but my way worked for me 
	install  file / install N Gage card game 
	select the folder of the game with the system folder inside it, do not select the the system folder but the game folder. 
	then copy & past the system folder to the eka2l1/Data/drives/ e if you don't see it create it 
	do this for all the games over write over the system folder if asked 
	now check if the games work, if not search on internet archive for another version of the game, a couple of times i had to del & reinstall the game (don't worry about this till you need to)
 
	To delete the game look at the system folder of the game and then look at apps in there you will see 6r21 (or whatever it is for your game), then go to eka2l1/ Data drives & search for whatever the number of the game is & delete all of them, then reinstall
 
	now you should be able to use (all but 1 (flo boarding)) of your games 
	now to install them into launchbox
 
	insall the eka2l1 Emulator & put this in Default  Command-Line
 
	--app %romfile%
 
	(you can put --app %romfile%--fullscreen if you want Fullscreen) 
	get my  command line (see link below) unzip it and use these as your roms 
	 
	intall them as roms. platform Nokia N-Gage 
	the Nokia N-Gage platform did not show up for me so i went to tools/ manage/ platforms and look for Nokia N-Gage. edit it and select the parents tab and select Handhelds (category) 
	then you should be able to see it 
	now the games  will work
 
	Thanks to all who contrabuted in earlier posts (without their help i could not have done this)
