Re: BlastEm 0.6.0

Hello,

Thanks a lot for this release! The addition of a proper options menu is great! :)
There's only one little issue for me with it: checkboxes look like they mean the opposite they should, ie. a black checkbox means "enabled", which seems odd.

Re: CVSD Compressed audio example

Hello,
A while ago I made this demo of a Z80 codec I made: http://sfx.gligli.free.fr/mddev/SoundChunks_Demo.7z
It's full sample rate (26390Hz 8bit mono) and uses statistical compression to achieve 8 minutes of music on 4MB.
There are a few bugs especially on sibilance but it worked fine already :)

Re: Algorithm for splitting sprites

I recently wrote an optimiser addition to SGDK rescomp to do something like this. It may be less thorough than this method because it still starts by cutting sprites in 32x32 pixels blocks but then eliminates transparent blocks and truncates others to the smallest possible sprite that holds all non ...

Re: Sega Genesis Dev Kit (SGDK)

Nice :) Thank you for getting the GCC6.3 toolchain integrated so quickly into the official version!

By the way, I was able to use GDB 7.12.1 with BlastEM 0.5.0 from within netbeans, that I use as development environment. It's a bit odd to set up but it works!

Re: GCC version VS performance

Stef: Great :) The integrated benchmark doesn't even benefit much from the new optimisations, benchmarking mainly ASM code. About GDB, I didn't have anything to test it, so it may just be compiled wrong... cero: vtimer is written by an interrupt and red by the main loop, that seems like a pretty sta...

Re: GCC version VS performance

Hmm, actually I think gcc-ar may just be a stub, something like that works as well with regular "ar" it seems:

Code: Select all

$(AR) rs $(LIB)/libmd.a --plugin=liblto_plugin-0.dll @cmd_
... And you get to specify the path for the LTO plugin ("." here)

Re: GCC version VS performance

... Nice! I was wondering if it was possible to have everything in one single folder. Compiling the library with LTO (and using it in a ROM) worked for me, and I think it would be nice to keep it to at least eliminate unused code. I think the errors you get are a matter of m68k-elf-gcc-ar vs. m68k-...

Re: GCC version VS performance

Hello, That new toolchain is available there as a somewhat clean commit: http://github.com/gligli/SGDK After some discussion with Stef and KanedaFr, I also included a recent GDB. Of course, I'm not sure everything works perfectly and I'm nowhere near a pro at building toolchains but I think this cou...
