Read, change and rebuild the six AKI wrestling ROMs

World Tour, VPW64, Revenge, WrestleMania 2000, VPW2 and No Mercy as .z64, .v64 or .n64. Everything runs in the browser; nothing leaves your device. Three things you can make here: a move of your own in the studio, a wrestler in the workbench, a texture in the paint view. Each one goes into a marked clone of your ROM that you download for the flash cart. The workshop above the ROMs needs no cartridge at all: what you make there stays in this browser and travels as a file. Explore holds the readers, Advanced the evidence and the raw bytes.

Several files at once are fine; every ROM gets its own node in the explorer. Opened ROMs go into the browser cache and are ready again the next time you start.

Checks

Two ratings, and the upper one needs no setting: the engine rating uses the decoded damage formula to work out what each fighter deals and takes against the same average opponent — health points and moves. Below it the weighted one: every column scaled linearly to 0..1, multiplied by its weight and summed; negative weights reward small values. Change the weights and both the ranking and the score column in the roster follow immediately.

Rules

Round robin

Field names with status "confirmed" are verified against the roster, "likely" fits the distribution, "auto" are bit runs with no known meaning. The checks run again on every load; each row says what is evidenced and what it rests on.

Field statistics across the roster

Fields with a single value across the roster have already been sorted out as constants. Wide spread means relevance to balance.

Solve the field mapping from the in-game editor

Clone a wrestler in the game into an edit slot, read off the parameter page and enter the values in editor order, one line per wrestler: Rock | 2 1 0 3 …. For every position the solver looks for all bit windows in the parameter file that fit every wrestler entered. Two or three wrestlers are usually enough.
