It is the third game of Contra in NES. System Different from Contra and SuperC,its system is new.We can select 1P or 2P at any time.Specially,we can even play with computer. Four players There are four players we can use in this game——BURNS、SMITH、IRON and BEANS.Each man has his special ability.But it doesn't mean there is much difference in them.After watching memory address,I find the power of all the weapon is same.The only difference is everyone's attribute.BURNS's jumping is the highest,BEANS moves faster than others,SMITH and IRON look not very useful. Bug There is a big bug in this game which we call it "super jumping".We can jump again after pressing "start".It means that we can jump all the time rely on this bug. Lag I think this game is interesting if we only play it.But I don't know whether is is suitable for tool-assisted speedrun because its terrible lag. Now I have finished stage 1.I am glad if someone can watch it and tell me something.

I'm agree with you Xipo, it looks like lag would be a big problem with this game, and I don't think there's much you can do with it. It was interesting, but the slowdowns were major and often, and it did take away from the enjoyability.

I wouldn't mind seeing more, but it's probably not the best choice for a submission. Definitely a very laggy game.

i hope i can see the movie ,all though with the bug about pressing start and high jump buttons can make time lag,but this game itself also can give our happy,so i think u should try it ~ 我希望能看到这部录像，随然有凭按开始加高跳的BUG和很大的延时，但这个游戏还是很有娱乐性的……你应该去尝试一下~

I assume the main reason it lags was simply the (U) label?

Hi! I decided to TAS this game now! I have made a WIP for it! http://dehacked.2y.net/microstorage.php/info/546737027/Contra%20Force%20%28U%29-GlitchMan-WIP.fm2 I picked Beans because he has the fastest running/walking speed but he also has the lowest jump but it wouldn't really matter since the majority of the stages revolve around walking. Now some key lag-reducing rules came into play: -jumping causes lag -killing all enemies on the screen is faster than just ignoring them and walking by -it is better to kill an enemy when there is a part with tons of lag during gameplay This is a game with lots of slowdown and it is not easy! I wasn't 100% sure what exactly was the best strategy to use for some parts of the level. I used a jump glitch in the middle of the level which I think is faster than just waiting for the platforms to come towards you since they move so slowly. Something else that could be a component of lag in the game is the parts of the stage that can be blown up (boxes, parts of a ceiling/wall, etc.). I noticed this during the truck part. There was nothing besides my character on the screen and there was parts of the floor that could be blown up and there were frames of lag there (normally there wouldn't be). And yes there were no other sprites on the screen. Anyway this WIP is what I came up with. Hope you all enjoy watching! :D

Awesome! Thanks! :D Guess what! I'm working on stage 2 right now! I am so excited to see how this stage will turn out (it's an overhead view and that would probably make it easier)!

Wow! That is better than my WIP! I was really shocked with how stage 3 went especially the part where you killed yourself in order to get past all those boxes! I was actually thinking of using that high jump glitch in stage 3 where the box launches you up high in the air and you can just skip a huge part of the level (I just discovered that trick the other night when I was playing it)! I did find an improvement in stage 1 that didn't require use of the jump glitch: http://dehacked.2y.net/microstorage.php/info/448283841/Contra%20Force%20%28U%29-stage1jumpingimprovement.fm2 Thanks for uploading this! This will definitely help me with my run of this game!

I found an improvement that could be made in stage 3: http://dehacked.2y.net/microstorage.php/info/962295849/Contra%20Force%20%28U%29-stage3improvement.fm2 You can still use the character to scroll (which is faster because the screen auto-scrolling part is 0.75 pixels/frame) as long as you don't make the screen scroll to a certain height in which case it would start the auto-scroll. Also, here is my improved WIP for stage 1: http://dehacked.2y.net/microstorage.php/info/220241814/Contra%20Force%20%28U%29-GlitchMan-WIP1.fm2 This time I have improved it by making sure to test which strategy saved the most time. I also kept up with the lag counter in Xipo's runthrough since most of the "saving time" part is based around reducing lag. So far I have saved 3.9 seconds (the duration of 234 frames)! I think I am making good progress so far! :D

I found a new shortcut in stage 3! Check it out: http://dehacked.2y.net/microstorage.php/info/1079496681/Contra%20Force%20%28U%29-stage3shortcut.fm2 I am not really sure if this will save time or not but I wanted to share this with you all! I thought it was really interesting and cool! :D

Oh,it is a surprising glitch. Someone in China(sorry,I forget his name)found another glitch in stage2,I call it Free-Walk,he cost two life to do it,and I improve his discovery,just only cost one life. http://dehacked.2y.net/microstorage.php/info/533202250/ContraForce-FreeWalk.fcm I am still not really sure if this will save time or not but there maybe a better way using this glitch.

I found another stage 3 glitch. It is where you don't have to shoot the controls on the left side of the screen and the down-scrolling will start automatically: http://dehacked.2y.net/microstorage.php/info/952180467/Contra%20Force%20%28U%29-stage3glitch.fm2 Also, here is my WIP for stage 2 (I abused deaths in stage 2 for less lag): http://dehacked.2y.net/microstorage.php/info/1095110703/Contra%20Force%20%28U%29-WIP2.fm2 There was a code where you could get 8 extra lives by holding B and pressing start but I have never gotten it to work. Does anyone know how to make it work?

As far as I know,the rom where you can get 8 extra lives is a hack-rom or (Unl)-rom,it doesn't work in Contra Force(U).You WIP is awesome!I notice you had got level 5 power before BOSS1,I think you can ues it when at level 4,then the hero can shoot three bullets together.Maybe,it can help reduce some frames in BOSS1.

Thanks! :D I wonder if there is any other way to get extra lives. Probably not because you get infinite continues in this game. So far I saved 817 frames (~13.6 seconds) off your run of this game! That is a huge improvement! The death glitch I used in stage 2 helped out a lot!

That is a huge improvement! The death glitch I used in stage 2 helped out a lot! In fact, I was thinking about using this death glitch in stage 1 as well. I wonder if it can save time in that stage since while you have invincibility after dying the screen won't start scrolling and you can go to the right and eliminate enemies as soon as they show up on screen. I just looked at the jumping for the characters and Iron has the lowest jumping, not Beans. In fact, not only does Beans have the fastest running speed, he has the second highest jumping height! I also found the address for the average walking speed for each character (located at 7E6 and 7E8): Burns - 01.38 Smith - 01.30 Iron - 01.20 Beans - 01.3F

I have a idea.We can get level 5 power before BOSS1.Wht not use this power and chang man?I mean we can Pause the game and use 2P(two hero/one control two)to beat BOSS1.Because of two heros,wo can go ahead without adding scroll/screen.By the way,let 2P die spmeplace in stage2.

That is a great idea Xipo! :D This means I won't have to worry about using up all of my lives on some stages where I use the death trick and I might be able to eliminate enemies and obstacles more efficiently.

After you get the roll attack (like the Screw Attack from Metroid), don't forget the triple fire, as those two are the only two power-ups that can overlap with each other. You can level up all four heroes before the final level, but I think Iron moves slower because of holding a Bazooka. You can destroy the final boss by rolling above it and not letting go of the A button and spam the B button, but you risk losing a life. There may be a way to manipulate this.

Here is the death glitch improvement in stage 1: http://dehacked.2y.net/microstorage.php/info/972948414/Contra%20Force%20%28U%29%20with%20death%20glitches-stage%201.fm2 That saves 732 frames (12.2 seconds) off my WIP and a total of 966 frames (16.1 seconds) off Xipo's run and that was just stage 1! This run is definitely going to be under 13 minutes!
