Pretty good stuff :)
I totally support patching TI's OS in order to make it less buggy, faster and more featureful ^^

If the 84+ C (SE) is to use a Z80, and its OS is to be based on the current OS and to be executed without emulation (which we don't know...), TI should fold in, or get inspiration from, third-party patches into the OS.

I had not realized that the combination of b_call lookup and copying the routine to RAM repeatedly was such a major bottleneck. Have you tried placing a counter in the write and erase routines and timing how long such operations actually take?

I notice you don't try to use the accelerated one-command-per-write mode. I wonder if the autoselect commands could identify whether the chip supports that.

I wrote the Wiki page on raw flash access.

Awesome, really :)

(TI should look at your patch and make it official :P)

They should, but so far, they even failed to make official the unofficial bugfixes... so optimizations are in another league entirely ;)

Alright, I just re-installed it and got the same error (after restoring the OS from a previous attempt). I waited a minute after installing it (it said DONE after executing), and a minute after booting. I still can't get the keys to respond. Could it be an issue with my apps?

Edit: could it be from my custom picture on zstart?

Does this mean archiving gets 3 times as fast?
And Texas, no I don't think this has to do with zstart since that's also written by thepenguin :)

Is grouping and ungrouping faster?

Are you sure that you used the version that goes with your OS ?
It worked fine for me on OS 2.43.

Yup, I'm on 2.55MP and got the 2.55 file. Does anyone have it working on this version?

I have a possible bug report. Since installing this morning my calc has been behaving rather oddly. I've been working on an axe project and using edit-from-archive and ON-ZOOM zstart features a lot, and suddenly (after the program crashed I think) the source axe file was filled with random tokens. This happened multiple times and eventually the dev cycle looped into restore axe backup, compile, archive source, run, executable crashed, go look at axe source, it's corrupted, restore axe backup. I tried restoring the OS, it went through the whole "Receiving...Operating System" dialog and then changed to "Waiting...Please Install Operating System." I then resent the OS (again) and now it's behaving perfectly normally. I have to do some stuff now, but when I have time I'll reapply the patch and see if I can duplicate the behavior.

The program throws an error if you run it on the wrong calc.

Which OS? I had to do this 5 times, so there's a chance I made a mistake in one of them.

Finally, someone with the same problem! So you're saying the patch only works when zstart is not installed?

Is the program dependent on specific hardware revisions by the way?

Also does the speed difference occurs only with very large files? I tried ROL2 with the patch on and could barely notice much difference. ??? However I was using an emulator. (Wabbitemu)

Oh, so I just tested it, and it apparently doesn't work when you combine zStart with MathPrint. The problem is definitely with zStart, but I have zero idea what would cause it. So try again with classic.

It's not dependent on the hardware at all.

It works on files of all sizes, but the bigger the file, the more noticeable the change is.
