That said, this is the first I've heard of this "RMSDK" option. So I asked ChatGPT about it, and it said:

"Practical conclusion

On stock firmware v1.1xxx5240, there is no supported way to add new fonts globally without modifying ePubs. The RMSDK hack route exists but requires low-level modifications and is not trivial."


Then there was some stuff about how you can brick your device, with this hack. I take the "not trivial" advice seriously. In any case, I do not have a T1, so I do not need code for that. I have a PRS-T2, as mentioned.

I really just came to see if someone can point me to where I can download a copy of rupor's AMR (Absolute Minimal Root) files, or open the minimal-root-zeam zip, so's I can root my T2, and install cool reader. Plus all the fonts my heart desires.

Does not look like that's going to happen. So it looks like I bought the T2 for nothing, and I might as well start looking at using my Kobo, once again. That at least is easy to modify with KOReader.
ChatGPT has it all WRONG. The hack is very easy to do. You just use Modify ePub to add the extra CSS code to all of the ePub you want and voila. The code will NOT brick your T2 and it will work. The T2 has the same version RMSDK that the T1 has. The non-trivial bit and the bit about bricking are 100% BS.

When I am at the laptop later today, I'll get the code. You'll have to try to see which code works. But what I need from you is the filenames of the font you want to use that you've put in the fonts directory that you created from the root. The code cannot brick your T2. The worst that can happen is that it won't work. But if it doesn't wors, that means it's the wrong code.
