6502 反汇编器和（重新）汇编器
允许将任何字节序列反汇编为唯一的反汇编文本，并且 将汇编文本重新组装成相同的字节（完全可往返）。 包括 支持具有多个助记别名和截断操作数的非法操作码 由 xx 表示。
用于反汇编 ROM（或 ROM 的一部分），将程序集编辑为 修补它，并根据更改重新组装。 另见：nes-game-genie 和 nes-file.
示例：
const {disasm, formatDisasm, reasm} = require('6502-reasm');
// returns an array, one element per instruction
const lines = disasm([0x78, 0xd8, 0xa9, 0x10, 0x8d, 0x00, 0x20, 0xa2, 0xff, 0x9a, 0xad, 0x02, 0x20, 0x10, 0xfb, 0xad]);
// returns a verbosely formatted text string, same as passed below
const formattedDisassembly = formatDisasm(lines);
// returns an array of bytes, identical as passed to disasm() above

6502-reasm
6502 disassembler and (re)assembler
Allows disassembling any sequence of bytes to a unique disassembly text, and reassembling the assembly text to the same bytes (fully roundtrippable). Includes support for illegal opcodes with multiple mneumonic aliases, and truncated operands represented by xx.
Intended for disassembling a ROM (or a part of a ROM), editing the assembly to patch it, and reassembling with the changes. See also: nes-game-genie and nes-file.
Example:
const {disasm, formatDisasm, reasm} = require('6502-reasm');
// returns an array, one element per instruction
const lines = disasm([0x78, 0xd8, 0xa9, 0x10, 0x8d, 0x00, 0x20, 0xa2, 0xff, 0x9a, 0xad, 0x02, 0x20, 0x10, 0xfb, 0xad]);
// returns a verbosely formatted text string, same as passed below
const formattedDisassembly = formatDisasm(lines);
// returns an array of bytes, identical as passed to disasm() above
