Nice, that means we can make it even faster now! ;)

SNES emulation might be hard for games like Star Ocean, Star Fox, Mario RPG or other games using all sort of special chips, but otherwise it should be easy. I guess even chipped games should be doable, but they would run slower. I think with Star Fox, you have to emulate an additional 30 MHz, right?

what about Super Castlevania 4?

I did just run nover with ndless 2.1
without having changed anything the nspire displays:

Base / CPU = 2
CPU / AHB = 2
Base / AHB = 4
Base = 240 Mhz
CPU = 120 Mhz
AHB = 60 Mhz

So Ti has made OS2.1 run the CPU at 4/3 of 2.0's speed and AHB  4 times faster

Very interesting, thanks.
Unfortunately, as allready noticed setting this on a previous OS is causing problems with screen refreshing.

Maybe TI has fixed the idle loop bug on OS 2.1 ?
Or maybe there is another parameter that has to be set...

changed base to 300 Mhz...





...esc





...screen still normal :) :)



Edit: Tested it Nspire is really another 4/3 faster

Wonderfull!!!

It would be great if we could overclock previous OSes to 300MHz base (instead of 180MHz) without having that screen problem.

Upgrading from 2.0 to 2.1 makes you lose 1.4Mb of free space.
It's useless to fasten the cpu, if we don't have enough free space anymore to store BMP/WAD files...

Check the free space available after a full reset with each OS in english language (can change but very slightly with another language):

Aren't all the languages stored in the OS, no matter what language is used?

Read about the patch.
The difference doesn't come from the translated system strings, but from the samples which are included in all languages in the TNO/TNC file. (around 15 languages if I remember well - that's a huge size!)
When you select the working language, the matching samples are extracted from the TNC file which is kept in "/phoenix/install/" and copied to the file system, which is making the little difference.

Code: [Select]
raw config: 2
Base = 300 MHz
CPU = 150 MHz
AHB = 150 MHzThese settings seem to work on OS 2.1 without any problems, and are apparently the fastest we can achieve through programs.
I'll keep these settings on my calc, and see if I run into any long-term problems...

EDIT: I also tried with raw config=0, but the calc froze...

Could we use an ndless program to delete those?

The samples are stored in something like 15 different languages in the TNO/TNC archive, which is stored in /phoenix/install/ . That file is vital for the OS as it is used at every boot.

You've got a PC program to delete those before installing the OS: TNOC.
A Ndless program won't be easy to develop, as you'll have to port zlib.
Moreover, if anything goes wrong with the Ndless program, your OS won't boot again (with TNOC, the patched file just won't install -> nothing dangerous).

Pretty huge difference indeed. I am still a bit scared of how large OSes will be in two years or so. X.x
