MSX FUSION-C, Talking about bugs, errors, mistakes

@anata : Did I miss to include a file in the example folder ?
Which sample code are you talking about ?

In Fusion-c/examples/ there is SUPERGIR.SC8
You must copy/paste it in the Working Folder/DSK/
if you want the program load it.

.SC8 are image file.
This type of image can be done by converting JPG/PNG file with a Image tool converter.
I'm using the online Jannone tool, available here : http://msx.jannone.org/conv/

Thanks a lot. I was sad... nobody answered .
I'm confused about why not to do a circle function for MSX1 but It's your work and is an awesome work, I swear.
I'll try the solution that you propose. Thanks again.

It looks like the implementation of install_isr and uninstall isr is missing. For me i now use something like this:

install_isr(void(*isr)void))
{
  unsinged int address = (unsigned int)handler;
  byte* mem = (byte *)0x38;

  mem[0] = 0xC3; //JP
  mem[1] = (byte)(address & 0x00ff);
  mem[2] = (byte)((address & 0xff00) >> 8);
}

But that is taking over the complete interrupt handler on adress 0x38 (and i left out here saving the original handler).
Another way is to just hook into 0xFD9A (KEYI) or 0xFD9F (TIMI), for example by using this wrapper library from Emily82.

There is no interupt functions actually implemented in Fusion-c.
"__interrupt.h" is a first attempt, but is not documented.

I'm really not a specialist, if someone would like help me and the community by adding ISR to FUSION-C with (documentation) It would be really great.

Someone ?

it sounds nice
