I'm not sure who created the google project mirror and if it's still active.

The up-to-date source code can be found here: https://www.unsads.com/scm/svn/nsptools/Ndless/trunk/Ndless-SDK/nspire_emu/ (guest/guest).

Is there any chance of moving nspire_emu to a new location for itself? It is quite dificult to mirror it this way :(. I believe it is a project on its own.

I've mirrored the project in Github https://github.com/antoniovazquezblanco/nspire_emu.

I've been trying to work on the sorce code for fixing warnings and for beeing able to compile it under both windows and linux.

After some work I realised that it no longer runs correctly under Windows and I don't know where I screwed up things so it would be very nice if any of you helped me find the mistake.

Here's a sample output:
Code: [Select]
./nspire_emu -1=Boot1cx.img -F=Flash.bin
Error at PC=00003B74: Invalid new processor mode

        Backtrace:

Any hint on this.

nspire_emu's source moved to https://github.com/OlivierA/Ndless/tree/master/Ndless-SDK/nspire_emu, so consider forking the whole ndless repo for now.

Ouch! This is very frustrating... Although it wasn't a great job I spent quite some hours working on this... I find ndless repo very messy and I see different projets inside the same repo which in my opinion difficult to maintain...

If you accept sugestions git submodules and different repos will be easier to work with...

I don't know what I will be doing. I just feel I wasted a lot of time in this project for nothing. I will probably abandon it in its poor state because I see I'm too out of the development discussion...

Thanks

Just do a quick diff of the two source folders, there are no huge changes, really.
I totally agree with you, the ndless repo is indeed a big mess. I tried to clean up some parts on my fork, but can't do anything as I can't really get nspire_emu to build under linux.. You might be able to fix this with your patches!

For being able to compile under linux you need to separate os dependent source files (gui and os) (done in my repo) and implement every function there for linux (not done). After that you should force 32bits compilation because of assembler (done) and you should add references for every symbol used both in c and asm to not include an underscore before them (done) so you will be able to compile in both platforms.

It is not very difficult to get done but it is sometimes tedious and ugly...

If I decide to continue on this I will probably try to clean up ndless repo first.

My patches are not difficult but they break the emulator in windows. If we are able to fix this issue it would be reasonable to merge my patches but not until then.
Do you feel in the mood for trying?

Thanks

I agree that it's very messy. IMO the Ndless installer/resources, Ndless SDK, Ndless editor, Luna, and nspire_emu should all be in different repos. Vogtinator has done some things to clean it up though, you should check out his repo at https://github.com/Vogtinator/Ndless.

Getting the nspire_emu kernel to run on anything else than win32 is a PITA. Just so overly many calls to windows-specific functions for which there isn't a simple equivalent in linux. I tried it once to remove the GUI stuff and get it to compile, but it stopped at an undefined reference in assembler to a win32 call. That was too much for me at that time and now I think it's easier to just use mingw and wine on linux..

Congrats Vogtinator for your work. Your repo looks quite good.

I've implemented some of the missing functions although there's a lot of missing work there but I meant to fix the emulator in win32 with mingw. It compiles but I'm stuck because it doesn't emulate as it is expected. If that worked I could be able to send the patches either to the main repo or to your fork.

It looks good, but apart from the SDK part nothing works :)
Just try to execute the generated ndless installer or resources, instant crash..

I just created a nspire_emu repo and made an initial commit.
Also, with the latest mingw32-w64 version it seems to compile on linux, and boot1 executes successfully!

Bad news: With newer MinGW versions it compiles and runs sucessfully, but the 3.6 ndless_installer.tns segfaults the emulator.
Any ideas?

My version of the emulator works now on Windows. I fixed that anoying mistake I made. It compiles under linux with gcc but it is far from being usable as there are a lot of uninplemented functions.

I will have a look to your repo Vogtinator to see your changes but I want to make sure we will be all working toguether so I think we should talk about how things are going to be organised to avoid wasted hours.

Thanks for your time.

Can you install ndless 3.6 successfully on your build of nspire_emu?
