i made a 144 mhz version of ljnes emualtor, it really better than the original 0.4 version from yoyofr. i compared it with a REAL american nes console with mario bros 3. its 100% exactly the same speed like a real nes. i tried the nes megaman series and same result 100% speed. the original yoyofr version always run between 90 to 95% real nes speed, if you notice it ;) and need autoframeskip. mine work perfect at frameskip 0. only exception i found, castlevania 3 need frameskip auto.

USE THESE OPTIONS WITH IT: vsync off, frameskip 0, 240 lines off, Sound quality and filter Medium and Low. and try mario bros 3 and megaman series

NOTE: But if you enter the menu during playing and you come back to your game , the fps will go down a lot, i dont know why. But anyway just choose the menu option you prefer , after that, choose EXIT to rom selector and choose your game. this way the fps wont go down. EACH time you reload a rom the fps are back to full speed. so reload the rom if you need to go to main menu, its important.

Have a great fun. ( i think yoyo must have done the 0.4 version of littlejohn at 144 mhz, its really faster, real nes speed, and a lot more fps, its look 60fps all the time. i tried mario bros 3, megaman 1 megaman 4 for my tests.

WE REALLY NEED TO ADD THE 144 mhz VERSION TO THE DOWNLOAD SECTION. thanks for uploader. i dont know how to upload. who can do it ?

180 and 200 mhz versions: if you really want to try these version with vsync ON go ahead, if you put vsync off, the game will be 400% speed.lol ( but it dont work well on gp32 blu+ with vsync ON, i dont know about the normal blu. BUT work perfect on flu and nlu): http://www.megafileupload.com/en/file/135309/ljnes180-200mhz-rar.html

note: if you tried my emulators, i would be appreciate your feedback about my modded emulators. just post it in this thread thanks
