萬能五筆2002分析筆記!

萬能五筆2002這個軟體好像已經有人分析了,不過我沒看到!我是昨天下午從作者主頁下載的,拿回來後就開始分析了,如果一定要說我是抄回來的我也沒辦法! (不過下面的東西絕對是我自己在家花了一晚時間整理的,絕對沒有抄襲!!!)

第一次做這麼詳細的分析,可能有很多地方錯誤,請大哥哥\大姐姐指正和支援!

【軟體簡介】:本系統的目的在於提供一種萬能的多元漢字輸入法，透過這種輸入法，可以克服現有技術的缺點，以多重（多元）漢字編碼代替傳統的單一編碼。具體地說，就是要設計並實現一種包含多種互不衝突、相輔相成、相互取長補短的漢字編碼方案的萬能漢字輸入法，即：在一種漢字編碼輸入狀態下，對任一個漢字或片語短語，同時存在多種編碼輸入途徑，從而提供更便利、更高效的編碼輸入。

我曾經追進:
:0040133E E8ADFEFFFF call 004011F0

後發現程式是把機器碼(我的機器碼是527901190)的ASCII的和X與某個數Y運算後得出一個數Z的十進位制就十註冊碼的前面部分!再把Z這個數的十進位制乘以二就十後面部分,中間部分是怎麼來的我就真的搞不懂了!唉........

我的機器碼的ASCII和是1D2再與某個數運算後得出CFC

CFC轉為十進位制是3324

我的註冊碼是3324-594401-6648

整個分析就到此結束了!謝謝您的觀賞!
