This Lua script displays when and that objects spawn, as well as some timers related to the spawning timing of candles and enemies. Work for all versions of Castevania Adventure, both GB and GBC.

About 50% of the game done, in collaboration with Exonym.

I didn't submit this because it's overall slower than the current movie: [4299] GBC Devil Island (China) "save glitch" by ThunderAxe31 in 01:56.08

Lua script that displays on screen the position and speed of the player. It does also display the position of enemies and other entities.

Anyone is allowed to use this file as base for making a full tas to submit to the site, without having to add me to the authors list.

In my strategy, I use both Potions and Red Turbo items in order to beat the enemy faster. Instead of having the P2 suicide, I had the P2 attacking the P1, so I used the alternate setup for triggering the glitch. I made only the first two battles, but I'm already ahead of the TAS made by NyXx, by few seconds. Maybe it could be possible to save even more time by hitting the enemy three times in the same instant, but I couldn't manage to do it.

tfw you save a fraction of a frame

Reuploading for fixing a minor issue, the previous file had

  max_states_global = 10

instead than

  max_states_global = 20

so now the script should work as intended.

Script that shows various info about enemies: attack, HP left, item drop. It does display an exclamation mark when the drop can happen.

Also displays current ATT and HP, of which both temporary and permanent values.

Works in 2 players mode, and displays independent lag counts.

Works with both Gambatte and GBHawk cores.

This is a resynced version of movie 3259. The only differences are are the addition of BIOS emulation and the equal length frames set to false.

Feel free to use this movie file for new projects, no need to add me to the author list.

175 frames saved compared to #6299: EZGames69's PCE Pac-Land in 23:09.63, in the first section of the first level. more explainations here

Level 1 cleared 44 frames faster than #6265: juef's NES Nebs 'n Debs in 10:25.39

Feel free to use this movie file as a base for new TASes, no need to include me in the authors list.

Script that calculates and displays the absolute vertical speed.

Also displays X position of helping in adjusting routes.

And energy left, just in case.

Saved 816 frames during the fourth boss, compared to this submission: #6281: McW4v3-X's NES Hello Kitty World "all balloons" in 31:29.9

Saved 180 frames in the first bonus stage, compared to this submission: #6281: McW4v3-X's NES Hello Kitty World "all balloons" in 31:29.9

Script for First Person View areas that draws a minimap showing:

• the map blocks (with relative ID for warp zones and computers),
• the player position,
• the player hitbox,
• the player facing direction.

Now displays the correct position in all maps.

Script that displays on screen the real speed for X, Y, Z, XY, and XYZ.

Now does also show the direction Harry is facing.

Script that displays the following values on screen:

• X and Y player position
• X, Y, XY total speed, of which:
  • X, Y, XY movements speed
  • X, Y, XY pushback speed

It does also display an arrow that indicates in which direction the player is heading.

Just as the name says: it forces the camera to be perfectly stuck on Pac-Man's position.

Note that it causes desync if used before approaching room exits.

First level done, by reproducing manually the inputs from this video: https://www.youtube.com/watch?v=DXB5DTYUei4

Script that displays on screen the terrain tiles. Allows to be able to see the level after triggering glitches that corrupt the graphics.

Now works correctly in worlds 1 and 4.

Displays on screen the position and speed of Pac-Man.

Script that displays X position, internal frame count and hidden lag count.

Warped to level 0, and glitched so hard that BizHawk changed resolution for reasons.

Managed to warp to level 0 without dying. You can't move, but you can still open the menu and quit.

This is just for comparing the RAM situation with the level 8 warp.

I tried to set up what would be an ideal new TAS. Still need to make sure that you can completely beat the game without stumbling into any softlocks...

Feel free to use this movie for your projects. No need to add me in the author list.

Lua script that displays useful addresses on screen, with the addition of real speed and absolute position.

I'm not going to continue this.

Feel free to use this movie file, no need to give me credit.

Also note I've made a lua script: http://tasvideos.org/userfiles/info/47648176198850991

This script displays on screen a grid and the position of the next fuel refill.

This script is a conversion for VBA-rr. For the BizHawk version, go here: http://tasvideos.org/userfiles/info/47351401452712727

It now correctly displays the whole OoB world.

Little script that makes easy and fast to change the vertical position of Harry, for the purpose of exploring the maps. Please stop script execution before entering another room.

Keep "O" key to make Harry rise, and keep "L" to make him descend. To stop the floating, just turn off the script.

You can change key buttons and vertical speed by editing the lua file.

Since the game uses many different addresses for the X and Y position of the player, I've decided to write a quick lua script that automatically tracks the addresses and shows them on screen. With some tweaks, the same code could be used for other games that feature the same problem.

Don't use it during the title screen, otherwise the script will crash.

updating with better code.

Fixed a bug that sometimes made the speed value slightly incorrect.

Also, the script now distinguishes between maximum jumping speed and maximum falling speed.

Script that calculates the average speed amount, starting from the moment it's launched. Every time you want to do a new measurement, you must restart script execution.

Now the script distinguishes between maximum jumping speed and maximum falling speed. Hurray!

Shoutouts to Spikestuff for the video that shows how to clip the floor by taking damage: https://www.youtube.com/watch?v=Wyfo6xXXlns

First, you need to spawn a money drop. Then, without picking it or making it going out screen, you destroy and keep hitting brick blocks. At some point you will get pietrified. Congratulations, you just hardlocked the game!

This script displays on screen:

• Player absolute X position
• Player absolute X lagged frames (counter resets at 9999)
• Player money
• Player experience points
• Experience points left for next attack level
• Current attack level
• Player HP
• Enemy HP
• Drops content
• Hitboxes of everything except D1 boss and final boss body

Also note that the watches will disappear while the pause menu is open!

This is probably going to be the final version. Enjoy!

same progress, but much time saved!

quick movie demonstrating how to make a round spiky enemy to go into a wall.

2 frames saved in Stage 16 thanks to door frame rule... I guess? All I've done was delaying the stair descending by 1 frame, then the boss skip resulted 2 frames faster.

Stage 16 doesn't need Fire ammo at all.

Pasted the latest s14, s15, and s16 by FatRatKnight.

The only differences are the amusing s14 boss door break and the removing of the Ammo Tank usage at beginning of s15.

We're almost there.

Everything has been squeezed out until Stage 13.

We're short on Laser ammo again and we need to improve the last three stages.

Refined test based on the first draft by FatRatKnight... Though it got 14 frames slower than the current main WIP. There is small room for improvement btw...

Edit: After some quick tests, I've noted that the first hit to the miniboss 6 would be dealt 6 frames later in the best case possible, making it unable to save any frame.

Based on FatRatKnight's ExternalRadar script.

It's a light script that enlarges screen in order to show, outside of game screen:

• spawning borders
• enemy spawns
• hitboxes
• enemy HP and invincibility time

Useful for fighting enemies when they are still outside of screen, and thus also managing Minibosses and Bosses skips.

Scripts that displays on screen the allocation of sprite memory allocation. Ultra-light version by ThunderAxe31, based on the basic script by FatRatKnight.

Colors:
Black - Free
Cyan - Player bullet
Green - Item
Yellow - Enemy (w/ 0+ HP reported)
Magenta - Enemy (w/ negative HP reported)
Red - No detected object -- Memory leak likely

1 Lag frame saved, the only one present in the stage.

Stage 1 resynced after the 8 frames improvement by keylie.

Desyncs again in Stage 4.

desyncs during boss fight

I had 7 frames saved until segment 5, but the level ended only 3 frames earlier. I guess I did something wrong in segment 6. Need someone to double check for possible improvements there.

Simple scripts that shows on screen all next item drops.

Quick movie demonstrating that triggering the Shot Counter Glitch is impossible with Wind weapon.

17 frames saved in stage 3, segment 2. the movie desyncs after the miniboss due to animation frame rule. Also note that the rest of the movie remained unchanged.

In order to achieve this, I simply used the bubble barrier again, just before segment 1 ends. This saved 10 frames.

Also, I discovered a new glitch. At 44842, you may notice that Zook does dash on ground right after the Flame Dash is ended, without having to mash the R button, but just keeping it. The game is actually continuing the ground dash started before the Flame Dash. Thanks to a different Y value, Zook managed to stay on ground after the flame dash ended, so he didn't need to jump and the ground dash didn't get broken. This saved 6 more frames.

Lastly, 1 frame was saved, probably for the different Y value, near the save platform.

Script showing on screen speed values

This is my attempt to resync the movie after having killed the first boss 5 frames faster. Due to bad RNG got after using the first Smart Bomb in level 2, it loses time with the locusts in level 3, and ends killing the first mid-boss 3 frames slower. Then the movie desyncs.

getting to talk to the major as fast as possible

Script I made that shows on game screen direction and speed values of last and priors frames. This will make micro optimizations much easier.

Test in which I catch two monkeys in the first level.

About the route: I'm not sure about the first monkey, but the second one I catched should probably be left last.

About optimization: I got the first monkey very fast thanks to the easy set up, and thus getting that earlier may be impossible. About the second one, it is very likely to be possible to catch it earlier with some precise analog inputs, but I need to know the address of the protagonist direction in order to know how to optimize it, otherwise it would be a blind struggle.

Desyncs during the boss battle due to damage and animation frame rules.

level 3 complete

"quick" test showing the luck manipulation strategy. not even a level was grinded before the boss, so this is very likely to be suboptimal.

I've manipulated luck in order to get as fewer random encounters as possible, and making the boss fight as fast as possible without having a single Digimon going ko.

Quick movie showing how to unlock controls after having used MurderBarrier

I managed to save a landing lag frame, just to be foreced to have another right after. Maybe there is something that can be done about it.

Resynced movie after 1 frame improvement by Tompa, but the final stage completion time resulted unchanged due to a frame rule.

Quick and unrefined movie from savestate demonstrating the midboss skip in stage 0.

Note that this movie uses a flying enemy that takes too much time to get near the midboss segment in order to get an actual time save.

Movie featuring the wrong warp glitch discovered by Dooty. Also shows off a game crash by hitting a breakable wall from point blank distance.

Movie file crafted by secret team "The Undecideds" during DTC6 by ThunderAxe31, BoboTheKing, DrD2k9, Dooty & Dacicus.

Floor entry point in level 16.

The idea was to continue moving to the right and then to the down through the walls, but for some reason I'm unable to continue at the end of the slope.

Note: this movie also features neat box tech, which will get useful for the 101% run.

Quick test for comparing to not using the level 1 cutscene skip.

Quick test that demonstrates the level 1 cutscene skip by opening the pause screen twice.

level 1 complete

Level 1 complete, 2 frames saved (again)
