WinUAE Debugger - showing bitmaps/gfx
Hello,
is it possible to display bitplanes with the debugger? I know address and dimensions of bitplanes or bitmap structure or rastport, is it possibe to display these graphics? (To see what certain drawing/blitting functions are doing? regards selco |

To answer my own question:
I found GfxRip V1.08 (https://github.com/rofl0r/GfxRip) that can be used to display/save pictures from WinUAE Statefiles. I used Misc/Save State (Ram Dump) . Not very handy but did the job. Maybe Toni could add a "Show mem as Pic/Sprite" feature to the debugger ;-) This could be helpful to understand code that creates/prepares graphics off screen) (1200 lines of C-Source are included in the GfxRip Archive) regards selco |

It would have nothing to do with custom chipset emulation. More close with RTG (=boring framebuffer) but still too different. It can't share any existing code.
It is someone else's problem, as usual. Sorry. |

@Toni
I was afraid you would say something like this ;-) @Codetapper Thank you very much for pointing me to your Maptapper! It looks very good and much more comfortable than GfxRip. I tried it quickly and found the gfx (Amiga Bootscreen) very fast. Really nice! I already read your interesting sprite tricks page in the past but missed Maptapper. As I wrote I wanted to use it to analyse gfx code in WinUAE debugger. Is it possible to save the Statefile from WinUAE-Debugger? (to have a state file exactly at a certain breakpoint or after a certain call) As an idea: would it be possible to connect Maptapper somehow to WinUAE debugger to have an automatically updated display? One last question for the moment: Can the display be set to match Amiga aspect ratio? (Pixel twice as high as wide?) selco |

WinUAE cannot save a state file from the debugger, it's only safe to save it at the top of a frame, hence why that won't work. I don't know how you'd connect the 2 programs together, if it's even possible sorry. In WinUAE you can save a memory dump at any point but you won't have all the internal state, just the memory itself.
As for your last question, I assume you're talking about a high-res Amiga display where you really want the width doubled not the height? There's no way in the current build anyway. |

I meant normal display like this.
But that's not a problem of course. regards Alexander |

Sorry, I thought you meant interlace (320x512) but you clearly mean hi-res (640x256). I'll see if the graphics component can handle scaling like that next time I'm making changes.
