CXII 模拟器用启动文件(BOOTROM)提取及补丁教程

mwzen0

计算器真机安装ndless并传入polydumper 5和eMMUlate


运行polydumper


稍等片刻，待程序提取完毕后按任意键退出
此时计算器内应已生成btldr.img.tns，btrom.img.tns，diags.img.tns，instl.img.tns，manuf.img.tns，osldr.img.tns


将这些文件发送至电脑。

————————————————

运行eMMUlate


按任意键开始


不必记这些十六进制数据，再按任意键生成二维码


扫码，两个二维码是同一个，扫码后应得到一串网址，该网址中已包含上上图中的十六进制数据。

————————————————————————————————————

接下来是给btrom.img.tns打补丁，可直接前往扫码得到的网址


上传btrom.img.tns文件后即可下载打完补丁的injected_btrom.img.tns文件


——————————————————————

为防止有人上不去github，故本人自制了一个本地补丁器，


在输入框中粘贴扫码得到到网址，然后点击[SELECT BTROM]选择btrom.img，再点击[PATCH!]并保存文件即可

I'm just curious, but why would you not want to just use the patcher on github.io? maybe it's some translation error?

Just translation error, the correct one is “to prevent someone who can’t reach github.io” (sorry for my poor English). P.S. In China github.io is reachable most of the time, but github.com isn’t

Ah I see, thank you!

sorry for my poor English

That's fine, I think it's great you can speak english... not like I can speak chinese haha

but github.com isn’t

Is this because of the great firewall? why would they block github?

it is pretty unstable in china to visit foreign website. sometime it work,but sometime not,for me,it depend on luck........

其实外国友人这么做是为了规避版权问题，没法直接把 dump 共享出来不然可能吃 TI 的律师函警告（但是 TI 大概率管不着这个中文论坛……）以及由于楼主已经把二维码发出来了，所以其实不用这么麻烦，直接用楼主的二维码就行 XD

It can be extremely slow to access GitHub within China.The deliberate degradation is likely due to the fact that GitHub can be used to distribute software (and other contents, e.g. using GitHub Pages) freely.
