calc-fighter

A SNES game written in C with PVSnesLib.

Requirements

• GNU make
• PVSnesLib (provides 816-tcc, wla-65816, wlalink, gfx4snes, ...)

PVSNESLIB_HOME must point at the PVSnesLib directory (the one containing devkitsnes/ and pvsneslib/), in Unix-style path form. The tools under devkitsnes/bin and devkitsnes/tools must be executable.

This project was built with the copy bundled in SNES-IDE:

export PVSNESLIB_HOME=$HOME/src/SNES-IDE/SNES-IDE-out/bin/pvsneslib
chmod +x $PVSNESLIB_HOME/devkitsnes/bin/* $PVSNESLIB_HOME/devkitsnes/tools/*

Build

export PVSNESLIB_HOME=/path/to/pvsneslib
make

This converts pvsneslibfont.png to .pic/.pal, compiles main.c, assembles hdr.asm and data.asm, and links calc-fighter.sfc.

Optional switches (environment or make variables):

Variable	Effect
FASTROM=1	FastROM build (default is SlowROM)
HIROM=1	HiROM build (default is LoROM)
PVSNESLIB_DEBUG=1	Keep intermediate debug files

hdr.asm defines LOROM/SLOWROM, so keep it consistent with these switches.

Clean

make clean

Game skeleton

File	Purpose
main.c	Setup, game loop, HUD health bars, round restart
fighter.h / fighter.c	Fighter state machine, move frame data, hit/hurt boxes, pushbox, sprite drawing
fighter.png	Placeholder sprite sheet: 32x32 frames in a vertical strip (frame order is FR_* in fighter.h)
tools/make_sprites.py	Regenerates the placeholder fighter.png (~/.venv/bin/python3 -I tools/make_sprites.py)

Controls: P1 is pad 0, P2 is pad 1. D-pad moves, jumps (up) and crouches (down), Y punches, B kicks, START restarts after a KO.

To add a character: draw a new sheet with the same frame order, and add or change entries in the moves table in fighter.c for its frame data. P2 currently reuses the P1 sheet with red/blue swapped (makeP2Palette in main.c).

Run

Load calc-fighter.sfc in a SNES emulator (e.g. Mesen, bsnes, Snes9x).
