Thank you very much Goplat. Now I can run 2.1 CAS

By the way Goplat, if you find the time, would you mind adding those access permission bits to the MMU before you get too busy adding support for OS 3.0 and Nspire CX?

Here you go. Version 0.51:

• Implement MMU access permission bits

It's just you. A program such as firefox, with all it's features takes up about 15mb of disk space.

Could you attach imgdump here too?

Thanks

Just wondering, but how many Hz does the nspire emulator get. My current version of the Prizm emulator achieves about 8MHz now on the average computer (I released the first test version yesterday), but I still have many more optimizations to do including multi threading.

On my computer, it typically runs around 100-200 million instructions per second. It depends heavily on the code being executed - plain arithmetic is fast, branches and memory accesses are slower, accesses to memory-mapped I/O ports are very slow. The main reason it's so fast otherwise is that I translate sequences of ARM instructions into the x86 code needed to emulate them, and execute that directly, so the overhead of figuring out what an instruction does is only incurred the first time it's executed. Without this feature, it's about 10x slower.

I have to ask: what hardware does the Prizm have whose emulation can be sped up with multi-threading?

Here is a version compatible with OS 3.0.1, made possible by returning the correct values from addresses 900A0000, 90110xxx, and CC000008. (Boot2 3.01 still doesn't work)
