Hola, TASvideos. I found this game and thought it might be entertaining, so I did a test run of the first stage up to the first boss. I didn't beat the boss yet, because I need some help finding RAM addresses (HP mainly). Anyways, there are a couple tiny tricks I've discovered already, but I feel like there should be some kind of glitch in this game that can be abused. I haven't found one yet. Here is what I found out so far: - Pressing duck for one frame before jumping, allows you to jump slightly lower than the minimum jump height. This is used to jump off of the switches to open the doors so I can enter the door quicker. - Turning around and suctioning to the ceiling at just the right spot allows you to jump up. This is used in one place near the beginning. - Suctioning to the ceiling but letting go before you actually stick to it is a good way to reach ledges without having to stop completely to climb the walls. - in one place, there is a block that is kind of in the way of a button, and I found that if you press suction briefly during the right frame while jumping, the block just falls through the floor. - in the section where you have to slide under a low ceiling and suction yourself to the other side, I found it faster to just let yourself slide a bit longer and dont use the suction at all. George can actually start walking while still in the wall. - Pressing duck on the right frame before room transitions causes it to transition faster. - You can pull enemies and objects through the ceiling if it's small enough. I haven't found any use for this yet though. Also, you can put enemies into the floor by ducking and repeated suctioning. Now, I have found the x speed and y speed, but for some reason I cannot find the x and y positions. Usually it's easy, I must be doing something wrong. Also, if there is a subspeed I haven't found it either. X and Y positions would be particularly useful I think, if I, or someone, can find them. Emulator used: Bizhawk 1.4.0 I used Bizhawk but unfortunately when playing back the movie I only get about 45 fps, so I can't get an accurate opinion on how fast the game looks, without a proper encode... All in all I think this is a good candidate for a TAS, even with the long boring tube rides. I believe the game has 7 levels based on stuff I watched on youtube, but I'm not entirely sure. Any thoughts on this? http://dehacked.2y.net/microstorage.php/info/389753327/Exxonym_JetsonsTEST1.bkm

Just do yourself a quick and dirty FFMPEG/Xvid BizHawk dump and watch it, shouldn't be much slower then just playing the input, and sure beats waiting for an encode. Edit: Watched your bkm, seems interesting and fast enough, although it desynch for me towards the end, cause I'm using 1.41 and didn't feel like downloading 1.40 Edit3 or 4: X screen scrolling position/camera is 2 bytes Little Endian 00134E Your position from left side of screen is 1 byte 001B85 Add both and you get global X position, resets when you change area. Y seems to follow the same format, but the memory position seems to change if X screen scroll position change, too hard for me to figure out atm.

I'm using 1.4.0 instead of 1.4.1 only because every other frame seems to be a lag frame in 1.4.1 for some reason, and I get even worse fps.

If Bizhawk's giving you problems I'd recommend you try out lsnes.

Good idea, I redid the first level (still no boss yet) in lsnes, and improved it a bit (~29 frames). http://www.2shared.com/file/hWowsage/Exxonym_Jetsons_noboss1_.html

Here are the first 2 levels. The second level boss is a revision, as I tested up to about level 6, and then realized bosses can be damaged with suction to a ceiling or wall. I then thought, well the second boss(es) have a ceiling, perhaps it could be used there. I was right, and in dramatic fashion the bosses died even quicker than I thought. Still using lsnes. http://www.2shared.com/file/3shKTx56/Exxonym_Jetsons_level2bossfix_.html [B]NOTE[/b]: The SECOND download button is the correct one, the first gigantic one is to something else and I hate that they try to sucker you into it. Go for the smaller one. There's also something I noticed in this game; After the third, fourth, and sixth levels there are bonus stages. I'm not sure what triggers them or if anything even does, but it would be nice to skip them. However after watching a LP on youtube, I have come to believe they are there no matter what you do. Sad because the one after the 6th level goes on for quite a long time (there's no way to end it early like the other ones).

Why not just use tasvideos userfiles to get around uploading hassles? http://tasvideos.org/userfiles/my#uploadfile

I've found a useful place to use a recently discovered glitch involving blocks and the vacuum. I haven't optimized it perfectly just yet, but it clips through to the boss, saving about 400-500 frames (estimate). Setting up the glitch to go through to the right is a little more difficult than the left, probably because of the way it's coded. It's still possible, it just takes more setup. Not including this glitch I've saved ~19 frames over my previous run so far. http://tasvideos.org/userfiles/info/16516528748322063

I went back and tested the first world pretty thoroughly. I found 2 instances where the clipping glitch can be used. Skips the whole tube riding section for the first clip, and I'm happy about that. That saves... around 611 frames of useless tube riding. I used the same drop down method into the little hole to position the block in the next room. It's way faster than setting it up the other way, in which I'd have to wait for the guy carrying the block so that I could get high enough. Second improvement comes from the boss in Stage 2. I found that there is one frame at the beginning where you can jump, and I use this to jump up into the boss on the right. I also found that if I position myself just right, I can land on the conveyor belt and when the damage animation bounces up, it immediately changes back to normal animation on the block, effectively cancelling a few frames of damaged animation. Damaging myself is necessary as I have to suction to the ceiling to do the instakill trick. Also I position the blocks so that I perform the stage complete dance in the air. This actually wastes 2 frames, but I think it's worth it for entertainment value. That's it so far, here are the first 2 worlds, in final form. http://tasvideos.org/userfiles/info/16681206809144819
