CGBitmapContextCreate error

[LiuSky]

I want to render with img_buffer, but the result is not correct. I would like to ask you which of my above screenshot code is wrong. Thanks for your advice @ToddLa

That is old code, current M4i does not render like that, it uses Metal...

[ToddLa]

You can get a image via MAME snapshot key....

[LiuSky]

It's finally the big boy. I know that currently m4i uses metal render. But I want to try using img_buffer. But it never turned out right. I'd like you to take a look at it. Thank you @ToddLa

I don't want a screenshot, I want a bitmap of the entire render. @ToddLa

Why? Rendering via CoreImage is old skool.

You can grab a snapshot after the Metal render?

Do you just need a frame snap, Or are you making a whole new method to draw, ie a new MAME iOS app?

Or maybe you can do what you want with a Metal Shader?

[ToddLa]

You should roll back (via git) MAME4iOS to a version that supported CoreImage and you will see how it used the software renderer

I just want you to look at how to render a bitmap using renderer_sdl1

And this is a MAME4iOS issue how?
