bmp2dhr

bitmap to double hi-res (bmp2dhr)

“Hi all,

Looks like Bill's link to grab bmp2dhr for macos is a 404 these days. Anyone have a link to a current site for the static binary?

Thanks!” — Presley Acuna macgui.com usenet: comp.sys.apple2.programmer

The makefile was tested using Linux. It should also work with macos using Xcode developer.apple.com

Notes

• The ulong type needs to be 32-bits, but using the C compiler on Linux, the ulong type is usually 64-bits which won't work. Search and replace is done to turn all ulong into u_int32_t.
• The b2d program will build for PowerPC Mac but doesn’t work because there are some endian issues with the bitmap file format. Here is a new build of an old PowerPC static binary that works:

  MD5 (b2d-powerpc-apple-darwin9.zip) = 4d4de2d5e423b887a542fff368aed299	31009 bytes
  MD5 (b2d) = 3c3ead03d8a6bcd47b697e9852979400	123992 bytes
