Ah I see now. That could probably explain it, although they could possibly have done like the Nspire series and release a different Casio FX-9860 Slim model for Europe and America.

Also is that Slim OS 2.00 you just listed public or did you find it as secret or something? I thought it stopped at 1.xx

On OS versions 1.xx, was there already a checksum like the OS 2.0x 0x24FFF8 checksum?
At which offset?

From OS 1.00 to OS 1.02
- OS checksum at 0x26FFF8
- Calculated as sum of 0x10000..0x26FFF7

From OS 1.03 to OS 1.11
- OS checksum at 0x26FFF8
- Calculated as sum of 0x10000..0x22FFFF + 0x260000..0x26FFF7

From OS 2.00 to OS 2.04
- OS checksum at 0x24FFF8
- Calculated as sum of 0x10000..0x24FFF7

I could modify the extract_9860g2_201.exe for get all the 11 flash files from the fx-9860GII osupdatedll.dll plus the binary installer, here is the list:
Note: I discarded extract0_9860g2.2o1.exe since it erases 3072 thru 3075 files.
extract_9860g2_201.exe (the orginal modified by cfxm) makes prizm3073 and prizm3074 (typeinfo1 ´95A and 495B)
extract2_9860g2_201.exe makes prizm3080 and prizm3081 (typeinfo1 ´97A and 497B)
extract3_9860g2_201.exe makes prizm3082 and prizm3083 (typeinfo1 ´98A and ´99A)
extract4_9860g2_201.exe makes prizm3084 and prizm3085 (typeinfo1 499B and 499E)
extract5_9860g2_201.exe makes prizm3071 and prizm3072 (typeinfo1 ´93A and 493B)
extract6_9860g2_201.exe makes prizm3075 and prizm3078 (typeinfo1 495E)

3071 to 3075 are for SH3, 3080 to 3085 are for SH4, 3078 the binary installer.

Oh well, my old nick was cfxm... :-)
And I don't want to bother you, but I have just attached the latest archive.

I didn't want to release this because I feared that Casio might start protecting the fx-CP400 setup. Now that I have extracted the OS 2.00 some days ago and Simon confirmed that Upload'n'Run is just working normally, there is no reason for me to keep this private any longer.

No problem, I did that earlier since I needed urgent one of the sh4 files for patch it and make it readable by fxremote

Wait, I thought you were another person, because you used a different account before ???

Also It seems that Casio protected the fx-CP400 setup anyway >.<

I still can get the OSUpdate.dll, so there's no problem after that (I haven't tried, though, but once we have the .dll ...)

I was getting too many PMs and emails on how to hack/upgrade with fxRemote, so I decided it would be best to just kill my old account and register with a new one. And this turned out to be highly effective...

Btw anyone got a fx-9860G Slim that could be messed around (as a guinea pig)? I want to test a .fls that I've patched.

This reminds me when I kept getting PMs non-stop about Omni administrative issues and had to change my nickname. In my case, though, the change to DJ_O didn't work, as it actually became worse afterward. The change to "DJ Omnimaga (Not Admin)" did work, though, and even after removing the Not Admin part it continued working except with a certain group of no longer active members (who I had to block PMs from).


That and when TI community members kept e-mailing me at my Hotmail address even though it was clear since half a decade by then that the gmail address was the one I primarily used.

Isn't fls an FL Studio file? O.O Sadly I don't have a spare 9860G, though.

Actually now that I think about it, it's Microsoft Reader that uses that extension. FL Studio would be .flp

.fls stands for flash (ROM image).
