# Follow-up roster additions Stock Euro 980123 `mvsc.zip`, cached opcode/data views from `analysis/mvsc_mash_20260913/`. This is a focused addition scan, not proof that every unlisted character lacks mash behavior. Read the named code paths rather than assuming every input read adds hits. ## Venom and Red Venom: Web Throw **Extra slam loop confirmed in code; ordinary Venom also confirmed live.** Venom selector `+$E6=$02` dispatches via `$03AB24` to `$03AD5A`. Red Venom's equivalent selector dispatches via `$067A20` to `$067C3E`. The command is HCB+P. Joe Zaza's original arcade Venom guide describes rotating the stick and pressing punches to obtain four slams: https://gamefaqs.gamespot.com/arcade/562630-marvel-vs-capcom-clash-of-super-heroes/faqs/6248 At `$03AD80`, the word `+$50` is initialized to `$0016`. Thus byte `+$50` starts at zero and byte `+$51` starts at 22. During the captured slam phase, `$03AF04` calls `$03B03A`: a new direction or punch (`+$DA & $007F`) spends one of the 22 required events. When byte `+$51` reaches zero, `$03B04A` writes `$01FF` to the word: one extra animation-loop credit in byte `+$50` and a negative flag/count in byte `+$51`. At an animation boundary `$03AF30` decrements byte `+$50`. Nonnegative loads group `$2C`, sequence `$1A` again; negative advances to release. The repeated animation contains two slams, so this turns two slams into four. Red Venom has equivalent logic at `$067F16..$067F26` and `$067E0C`. Live trials use native ordinary Venom selection and HCB+LP, restoring the same seeded save for none, tapped all buttons, rotating directions, and both. `venom_webthrow/webthrow.csv` and `.log` contain the results. - No mash: damage events at callbacks 38, 65, 95, 120: initial grab, two slams, final throw. Move exits after callback 158. - Button taps: threshold write `$03B04A=$01FF` at 81; damage events at 38, 65, 95, 122, 154, 178: initial grab, four slams, final throw. Move exits after callback 216. - Directions and combined inputs also cross the threshold and produce four slams. One update containing several qualifying inputs still decrements the threshold only once. **The native combo display remains 1 throughout this grab.** It does not count each slam as a separate combo hit, so a peak-counter-only test misses the extension. Also do not promise a damage increase: `$03AED8` switches the victim's damage attribute from `$35` to `$36` after the threshold, and the button/no-button trials both ended at 110 HP from 144 in this fixture. Extra slams were individually weaker. Direction trials ended at 107, but their first damage event already differed, so that is not an isolated measurement of the added slams' damage. ## Red Venom: Venom Rush **Code-confirmed repeating attack; live-tested independently by the War Machine subtask (see `war_machine/red_venom/`).** QCF+K maps to `+$E6=$04`, dispatch `$067A20+4 -> $067F2E`. Human setup clears loop byte `+$50`, the normal input buffer `+$DE`, and local buffer `+$398`. Initial animation is group `$2C`, sequence `$3A+strength`. During the move, `$068024` accumulates newly pressed buttons in `+$398`. At an animation boundary, `$068030..$06803C` merges new presses, `+$DE`, and `+$398`, then checks kick mask `$0700`. A qualifying event increments loop byte `+$50`; `$068062` always decrements it. Consequently, a new kick cancels the decrement and another attack animation is loaded at `$06806C..$068072`. Without a kick it goes negative and exits via sequence `$46+strength`. Punches do not satisfy the test. This is an inline input-extension path, so a census of calls to the common `$01A3CC` helper alone would miss it. ## Strider: Ouroboros **Code-confirmed punch-triggered projectile firing; no live test here.** The super's player routine `$05AA92` creates two orbiting objects through `$05AB5A -> $093850`. The allocator differentiates them with `+$27=0/1`. Each object's timer is initialized to `$F0` (240) at `$09393C` and decremented at `$0939E4`, without a button-based duration refill. When its firing cooldown `+$B9` is zero and the owner passes the state gate at `$093A56`, `$093A5E` reads **the owner's** newly pressed inputs `+$D4` and masks punches `$0070`. An accepted event calls projectile creator `$094A72`, then initializes cooldown `+$B9` to `$16` (22). The cooldown decrements at `$093A76`. Thus punch tapping fires additional shots from the satellites during the existing effect. It does not lengthen Ouroboros. This is another path outside the character's own main code block. The contemporaneous move list also describes QCF+PP followed by repeated P: https://zachd.com/mvc2/movelists/mvc.html ## Spider-Man: Web Throw rotation boost **Adjacent input-sensitive throw mechanic; do not claim extra damaging combo hits without a live test.** Routine `$03DF76` enters the captured rotation phase. `$03E0D8` initializes spin credit `+$38D=1`; `$03E0DE` initializes a two-cycle counter `+$50=2`; `$03E0E4` initializes a separate five-rotation cap `+$51=5`; a window timer starts at 25. At `$03E318`, held facing-relative directions `+$D6 & $000F` accumulate all four cardinals in `+$389`. Completing the set twice grants one `+$38D` spin credit, adds two to `+$38C`, and adjusts `+$38A` by `$FDE0` (-544). The timer clears incomplete sets. Animation events can clear the direction set too. This is not an arbitrary button-popcount helper. `$03E154` consumes spin credit at an animation event. A separate cap stops continued spinning. `$03E12E..$03E13A` uses `+$38C` to advance the animation more quickly. At the final throw, `$03E1E6` derives a value from `+$38A` and calls defender helper `$01B57A`. The opponent's escape helper at `$03E2F2 -> $014436` can reduce `+$38C` and move `+$38A` back toward zero. This is a rotation/throw-strength interaction, not proven extra hit-counter hits. ## Other quick-scan observations Captain America reads mainly lead to normal repeat/cancel handling. Gambit's punch check `$038D2E` sets a one-use latch (`+$4E`) and starts a follow-up animation; repeated presses are then ignored by the nonzero latch. Spider-Man's `$03D9C4` punch check similarly latches one follow-up under hit/animation conditions. Strider's `$05C008/$05C026` recognizes a forward/back input sequence with a 15-update timeout; it is not a hit-extension counter. Captain Commando had no obvious direct new-input read in this bounded scan. These observations do not establish exhaustive negative results for those characters or their children.
