Is it possible to port .8xk apps to work for the TI 84 Plus CE?

Question

I'd like to be try this calculus app (or the "fixed version") on my new TI 84 Plus CE. However, the PrettyPt and Symbolic apps, which must be installed prior to use, are given in .8xk format, which means they are not usable in the TI 84 Plus CE (as it uses .8ek). A separate Symbolic download can be found that includes Assembly source code, but the PrettyPt download does not have such. Is there some other possible solution or work-around in order to get the Ultimate Calculus Collection to run? Or, for that matter, is there any general way to port .8xk's to the TI 84 Plus CE?

Answer 1

针对微积分应用程序的TI-BASIC源代码适用于与TI-84 + CE兼容的大多数用途。即便如此，移植此工具仍存在许多障碍。

• BasicBuilder是用于将程序集转换为应用程序的工具，不适用于TI-84 + CE。部分原因是：
• 目前无法为TI-84 + CE创建应用程序，因为TI尚未发布应用程序签名密钥。计算器社区不会很快期待这个密钥。
• 对于装配部分，包括PrettyPt和Symbolic，TI-84 + CE使用ez80 CPU，它与z80兼容。完全重写代码是不必要的;但是，所有系统调用现在都不同，这需要装配技能和大量修复工作。

总之，不可能将该工具作为应用程序移植，即使它是，它也可能比端口更容易重写。
