Finally!

Black Magic is an editor for The Legend of Zelda: A Link to the Past, on the Super Nintendo Entertainment System. Its philosophy is to provide data expansion whenever realistically possible, circumventing the limits of the original game through expansion of the size of the ROM image. It seeks to provide ways to avoid arbitrary, hard to spot ROM corruption by making most data changes visible as text files. It seeks to provide intuitive ways to import and export different types of data between different ROM images.

This is the first major release of Black Magic, and while it is still missing quite a few features, it represents a large step forward from previous builds.

v0.09a changes:

1. Fixed sprite loading and item loading.
2. Changed overworld editing mode buttons to bitmapped checkboxes that stay down to indicate which mode is active.
3. Right click menus for the select objects and handling thereof (hflip, vflip, palette changes).
4. Sprites and Items numbers can now be changed. (Enter two consecutive hex digits to see a change)
5. Graphics exporting has been corrected.
6. Overworld Map navigation by holding Ctrl and clicking near the edge of the map to go to other areas.
7. Everything I've ever coded for Black Magic b/c this is the first readme file I've done for it.

v0.09a stuff that is known to not work

1. Don't bother messing with the overworld exits (the white markers), changes to those won't save in the ROM or the assembler files (hooks.asm and owData.asm).
2. The tile drawing mode only supports tiles that are already found on the map. Be patient, I'll have support for arbitrary tiles in the next release.

v0.10a planned changes:

1. 8x8 tile palette and hflip / vflip / palette controls for draw tile mode.
2. Investigate switching Text and Dungeon editing changes to use assembler rather than raw binary writing.
3. Graphics Importing
4. Minimap Navigation for Overworld
5. Custom Object editor
6. Additional stock objects - whatever's feasible, but entrances primarily

If it all sounds good, give it a look and download.

Looks very promising! I look forward to seeing the development of this tool!

I just downloaded this and a rom to test it on. I feel... curious.

In the overworld edit mode, I find it humorous to see that hovering over the map shows a screenshot in the overworld toolbar window (which isn't really a "toolbar" at all, is it?), which includes the menu bar and parts of my desktop. Oops?

It's supposed to show the current 32x32 tile, but yeah, if the tool window is nearby it will pick up some of that. Never seen parts of the desktop get into it though... In any case, I never really understood why this happens, but I haven't bothered to try to fix it yet. I wouldn't think that the device context for the map window would contain graphical data from windows that hover above it.

Here's the code in the WM_MOUSEMOVE handler that updates that little window.



        HWND zoomWnd = GetDlgItem(game->toolDlg, IDC_MAPTILES);
        HDC srcDC    = GetDC(game->pictWin); // the main map window
        HDC destDC   = GetDC(zoomWnd);

        // ---------------------------------------

        // magnifies the current map32 tile by 4x and sends it to a view window
        StretchBlt(destDC,
                   0,       0,
                   128,     128,
                   srcDC,
                   x32 ,    y32,
                   32,      32,
                   SRCCOPY);

        ReleaseDC(game->pictWin, srcDC);
        ReleaseDC(zoomWnd, destDC);

Yeah, point is, that's how screenshots are made.

The toolwindow is in this case not overlapping the main window. I point at a tile near any edge of the client area, and it'll blit that entire rectangle, even though it covers out-of-map areas.

It's really more of an on-screen magnifier as it is now.

What I'd do, personally, is check which tile you're pointing at, then use that info to draw it in the toolwindow. As a tile, not a screenshot.

Doing it as a screenshot also looks weird in that animated tiles aren't animated in the toolwindow -- you take a snapshot of the current frame, after all.
