@mr_sis yes there is, you can find it in category extentions

"It looks like this game (US and JP versions) will be available this summer in the Contra Anniversary Collection. Switch, PS4, XBox One, and Steam will all be valid emulators."

from emulator specific rules, so that should give you an answer

If you use netplay through fusion i would suggest using some kind of vpn (like hamachi, for example), cause otherwise you'll have a pretty rough time. If vpn doesn't help, then there is probably something wrong with your connection.

if you talking about getting sonic to move faster and jump higher - that is actually not a glitch - you get these properties when you enter the gun and lose them when you leave the screen. this has already been used in both any% and glitchless for quite a while

yes, because it supplies the same voltage and amperage

i would suggest you to ask such questions in sonic discord, but basically - you spindash not optimally and your spindashes are not that great

General tips for 2p runs:

1. The best pair is quite obviously Fang and Browny since they have the most powerful weapon sets.

2. Weapons have their damage about 20% reduced and damage registration happens every other frame for each of the players and it's kinda wonky (it doesn't always hit).

3. All of the upgraded As have the same DPS, but instead of every 4 frames, Browny's A deals damage every frame, making it completely useless in two-player mode

4. On jungle stage, the (snowman thingy??) can only take damage every 4 frames in both 1p and 2p mode, so it doesn't matter if one or two players shoot at it (making Fang's glitched charged shot the best thing to kill it)

5. It is difficult to manipulate jungle's final boss last phase position, so if your pair has Fang, let him solo kill it with GCSs, for every other pair it's better to just use As on different sides of the screen to keep it in center (can't say anything about using Browny's C on it though)

Elevator boss as Sheena: With the first phase of the elevator boss, he can either stick to the top, right or left.

It is always preferable for him to go to the top, because you can easily deal enough damage with just C to him to start the second phase, where you use one of two bombs you have at that point.

But in a PB attempt or a marathon run, if he goes to the left (the worst scenario) or to the right (acceptable, since it is the fastest), it is worth to use a bomb there just to deal enough damage for him not to start the first phase again.

Optimal (?) Big Magnum fight as Sheena on JP: I missed a shot on phase 2, but the first phase here is done before he went shooting from the ceiling for the second time. An ok fight would look something like this: Missing one cycle in the first phase loses probably 2 to 3 seconds. Dodging that projectile in phase 2 is simple enough with a bit of practice For the third phase you need to shoot him with C about 10 times and use the bomb while those beams fully form and start moving, the game gets laggy and this will give you enough damage to quick kill him.

One-cycle chase boss as Ray. Simple enough. It is actually possible to one-cycle him without using the bomb but its not easy at all I used JP, but you dont actually need to take a hit, it just makes the quick kill a little easier. I got it 3 times in an hour long session of doing it, so i dont think its worth going for yet(unless you really need that extra bomb)

An easy, safe and consistant strat. Your safe space is when your foot barely touches that piece of junk ( it's not super presice and there's plenty of time to adjust). His hitbox is kinda weird, but extremely generous. It is actually possible to kill that boss faster in JP by damage boosting (saves maybe like .2-.3 at best, so not worth it) or using bomb (not viable in chase/surrender, dont know about other categories)

Viable on US version as well, but is kinda tricky. Not taking a hit does not seem to save time for JP version.

You have to shoot him 3 times with C, after the first phase is done you need to go either to the left or right corner as soon as possible, take a hit and this will give you just enough I-frames to one-cycle him in the second phase. One C shot is enough for the first phase, but the one-cycle will not be as consistent.
