Active ReC98 subscriptions for June 2026: • €125 from [Anonymous] towards anything (including tooling) • €50 from Ember2528 towards better replays for Shuusou Gyoku, followed by a long-term plan to first decompile TH03, adding replays, porting it to modern systems, and then implementing netplay (although we're also going for a more short-term option of having netplay on PC-98) • €35 from [Anonymous] towards TH03 RE • €10 from Root towards porting SDL to Windows 98 to get Shuusou Gyoku running there again
Output of the upcoming Shuusou Gyoku command-line replay simulation tool, showing a desyncing replay that ends 77.1% into the recorded replay data with a Game Over, after just 24.6 ms of simulation time.
Output of the upcoming Shuusou Gyoku command-line replay simulation tool, showing the end result of two Extra Stage and one Lunatic Stage 4 replay, together with the surprisingly short amount of time it took to gather these results – 141.3 ms for a Wide Shot Extra Stage run, 173.3 ms for a Homing Missile Extra Stage run, and 44.8 ms for a Laser run of Stage 4 on Lunatic difficulty, translating to validation frame rates of 191894, 151244 and 242082 FPS, respectively.

First Shuusou Gyoku comparison screenshot of the randomness in Stage 6's fake script code, shown all throughout VIVIT-captured-'s third phase. Taken during that phase's entrance animation.
First Shuusou Gyoku comparison screenshot of the randomness in Stage 6's wavy clock background and falling stars. Taken at the start of VIVIT-captured-'s first phase, on the specific frame before her first pattern.
First Shuusou Gyoku comparison screenshot of the randomness in 1) the falling rocks in Stage 4, and 2) the stars shown when collecting point items during an Evade combo. Taken, obviously, at the start of Stage 4's second wave of enemies, and also demonstrating the random spawn position of some of the enemies in this wave.
First Shuusou Gyoku comparison screenshot of the randomness in 1) the hearts shown when losing a life, and 2) the sparks shown when grazing bullets. Taken at the start of Stage 5.
Zoomed-in screenshot of incorrectly rendered item popups with negative values as they will appear in the ReC98 P0339 build of Shuusou Gyoku.

Screenshot of Shuusou Gyoku's Config → Difficulty menu in a build compiled with the PBG_DEBUG macro, showing pbg's four debug options, with the collision-detection-deactivating `Hit [O F F]` option highlighted. The help window describes it as 「[DebugMode] 当たり判定」.

Screenshot of the barrage of formulas involved in deriving values from TH03's round speed variable, taken from the ReC98 2026-03-16 blog post. It reads: "This variable is then used to derive a whole variety of speeds and limits: • Speed of pellets and fireballs while they transfer to the other playfield: (4.375 + ⌊round_speed/3⌋) • Speed of the single pellet fired when killing an enemy with an explosion whose chain has a hit count of ≥3 and ≤(14 - (⌊round_speed/2.0⌋ × 2)), after it transferred to the other player's field: (1.5 + (⌊3 × round_speed⌋/16)) • Additional fireball speed added on top of the randomized base speed between 1.25 and 3.25: ⌊round_speed/2⌋ • Required charge_exatt within a chain to fire an Extra Attack after destroying a fireball with an explosion: (7 - ⌊round_speed/2.0⌋) • Required charge_exatt within a chain to fire an Extra Attack after destroying a fireball with a regular player shot or Charge Shot, or an enemy with an explosion: (6 - ⌊round_speed/2.0⌋) • Required charge_fireball within a chain to fire a fireball after destroying an enemy, fireball, or pellet with an explosion (12 - ⌊round_speed/1.0⌋) • Two other things in character-specific Extra Attack code I haven't RE'd so far Yup – the difficulty setting in the Option menu merely controls where all of these values start out at. After 6,144 frames of gameplay, or 1:49 minutes, even an Easy round will have accelerated to Lunatic levels."
Screenshot of a video that visualizes TH03's frame data of a fireball-originating explosion against a pellet, demonstrating how these explosions are rendered 8 pixels lower than the position that collision detection uses for their hitbox. Taken from the ReC98 2026-03-16 blog post. The caption reads: "Thanks to the anonymous backer for providing the Anything budget for these multi-row tabs at the end of the 6th push!"
The table of contents of the upcoming 2026-03-16 post on the ReC98 blog. It reads: 1. An important note about durations in TH03 2. TH03's chaining system 3. Difficulty-specific tuning • round_speed • enemy_speed • Angle tuning 4. TH03's combo system • Boss Attacks and Panics 5. TH03's enemy formation scripts • Gameplay details • Function reference 6. TH03's enemies themselves 7. TH03's explosions 8. TH03's fireballs • Destroying fireballs with regular player shots or Charge Shots 9. TH03's score reduction and extend glitches • The fix (← new builds here!) 10. Completing the Fediverse migration • Polls • Bluesky rant, part 2
Work-in-progress screenshot of the TH03 explosion hitbox figure from the upcoming ReC98 blog post, displaying the hitbox of an explosion that originated from a 48×48-pixel enemy against a 64×64-pixel enemy. With 5 different kinds of explosions (from 16×16/32×32/48×48/64×64 enemies or fireballs) that can hit 6 different types of gameplay entities (16×16/32×32/48×48/64×64 enemies, pellets, or fireballs), there are a total of 5 × 6 = 30 hitboxes that the blog post has to visualize, which necessitates two layers of tabs and some coding effort to make it work nicely.

Command-line output showing a metadata comparison between the original lossless WebM file for TH03's enemy formation #3 and the resulting blob of the Bluesky upload, downloaded via `goat blob export`, via ffprobe. Shows how Bluesky not only converted the video to H264 with YUV420P chroma subsampling (the same format Twitter enforces for its videos, which is bad enough), but even chopped the video down to 30 FPS, losing almost half of all frames in the original video.
