zeromus 892e7cb5f5 change how memory is allocated to clean up a lot of messed up junk (mainly strange alignment adjustments which didnt completely make sense and frees which didnt match the allocation function that was used). 
In case there are problems on other platforms (a few seems probable), here's the idea
1. Get rid of all manual alignment adjustments
2. use FCEU_malloc or malloc, as you see fit
3. use FCEU_free (or FCEU_gfree) if you use FCEU_malloc or FCEU_gmalloc. There's no real reason to need FCEU_gfree; this rule might be eliminated in the future (at which time FCEU_gfree will be removed)
4. If you need more alignment, increase it in FCEU_malloc. It's unlikely more alignment will ever be needed.

On windows, since the FCEU_*malloc functions now use aligned_alloc, we will catch instances where free() is used to free them (which happens frequently). allocates and frees should be matched. fix the free call if you ever observe this happening.

also

5. In general, remove crufty error handling for allocation failures. This just gunks up the code. If allocation fails, the application terminates.

vc make scmrev command work like desmume does (using system32 directory instead of sysnative). this probably fixes #459? or if not then desmume is broken, too. I'm not sure why the 32bit version can't be used every time. I think it can be. 2022-08-08 21:19:45 -04:00

fceux Build status

An open source NES Emulator for Windows and Unix that features solid emulation accuracy and state of the art tools for power users. For some reason casual gamers use it too.

Builds and Releases

Interim builds:

But you might like mesen more: https://github.com/SourMesen/Mesen

You should get releases from here: https://sourceforge.net/projects/fceultra/files/

That's because github forces us to use tags we don't have for releases.

2.6.4 is the most recent release but most people are using the autobuilds.
