USE_DEBUG_SHOW_PACKET perfect

`\src\constants\ServerConstants.java Add: public static boolean USE_DEBUG_SHOW_PACKET = true;

\src\tools\HexTool.java

Add: public static final String toStringFromAscii(final byte[] bytes) { byte[] ret = new byte[bytes.length]; for (int x = 0; x < bytes.length; x++) { if (bytes[x] < 32 && bytes[x] >= 0) { ret[x] = '.'; } else { int chr = ((short) bytes[x]) & 0xFF; ret[x] = (byte) chr; } } String encode = "GBK"; try { String str = new String(ret, encode); return str; } catch (Exception e) { } return ""; }

\src\net\mina\MaplePacketDecoder.java search: out.write(decryptedPacket);

Modified to:
